In Daye, Hubei Province, the mining industry has a long history and the bronze is thick and flowing. From the digging well in the Shang Dynasty era to the Castle Peak Field Institute in Tang Dynasty, it has been smelting for more than 3,000 years. Discovered in Daye Tonglu Mountain in 1973 The ancient mine sites fully verify the origin of the Daye smelting culture.
Thousands of years have passed by. The Daye Nonferrous Metals Group Holding Co., Ltd. (herein referred to as 'Daye Nonferrous') was founded in 1953. It has passed the era of pioneering business and has ushered in the splendid development of Jiazi and become China. The main force of non-ferrous mining group's innovation and innovation. In recent years, Daye Nonferrous, through a series of technological transformations and equipment upgrades, has rejuvenated the vitality of the old state-owned enterprises and has successfully ranked among the top echelons in the Chinese copper smelting industry.
Outotec is a world leader in Finnish beneficiation and metal smelting technologies headquartered in Finland and has a history of more than 100 years. Outotec is unique in the world for its innovation, environmental protection, energy saving, safe and sustainable technologies and processes. Since Outokita entered China in the 1960s, it has been committed to introducing the most advanced technologies and concepts into China. Since 2002, Daye Nonferrous and Outotec have continued to develop technology, equipment, and business cooperation. Joining hands to create winners has added a chapter to the cooperation between China and Finland in the field of non-ferrous metals.
The roots of two big trees are connected
Entering the melting shop of Daye Nonferrous Metal Smelting Plant, the 79-meter-high smelting furnace main building stands in a dense tube gallery. The reporter took the elevator to reach the main control room of the 29-meter platform, and various operators operated in front of the monitoring screen. The data is vividly visible. Push down the partition door and look down. The height is 16.4 meters. The Ausmelt top-blowing furnace with an inner diameter of 5 meters runs smoothly. The sound rumbling and the heat wave burst.
Wang Chengguo, the chief of Daye Nonferrous Metal Smelting Technology Department, pointed to Ausmelt furnace and told reporters: 'The Daye's non-ferrous Ausmelt furnace uses pulverized coal as fuel, with a processing capacity of 230 tons per hour, which is by far the largest in the world. The O.R.O., oxygen rich concentration is also relatively high, can reach about 63%, with PS converter and rotary anode furnace, anode copper casting using two Outotec disc casting machine, stable operation, reliable performance.
Since the beginning of the 21st century, with the depletion of copper resources in China, the proportion of imported ore has become higher and higher, and the composition of raw materials has become complex. At the same time, the national environmental protection policy has tightened and tightened, and the upgrading of copper smelting technology has become a must for copper companies. The challenge of reality is that Daye Nonferrous is in urgent need of a new energy-saving, environmental-friendly, green smelting process to replace the existing process equipment. Wang Chengguo recalls: 'Before and around 2008, Daye Nonferrous was inspecting various smelting furnaces commonly used in the world. There are three prerequisites that must be met: First, the raw material adaptability must be strong; second, the production process should be short; third, the output must be high. After many choices, careful measurement, the ultimate use of Outotec's Ausmelt top-blowing smelting furnace . '
The reporter interviewed smelters
It was a period of intense effort to work together to catch up. After the contract was signed, the two parties immediately launched intense work, training, installation, commissioning... Outotec sent a group of engineers to eat in Daye Nonferrous, with Chinese technicians. Through coordination and installation, it has been installed and commissioned around the clock. On December 31, 2010, the Australian furnace system was successfully tested and the first batch of anode copper was produced on the same day. When the orange-red copper water flows into the disc casting machine, all the Chinese and foreign The staff cheered spontaneously. Daye Nonferrous and Outotec Du Ming remembered this historic moment.
Luo Wei, currently the deputy director of the smelter, recalled: “Ottotec's technical staff has rich theoretical data, but Daye Nonferrous has decades of smelting practice, and theory and practice have been perfectly integrated here. When confronted with technical problems such as computer data collection, temperature control, gun pressure, etc., both Chinese and foreign parties have also fought at the same time. They eventually explored together and resolved the roadblocks together. Outotec engineers are very dedicated, and during installation and commissioning, We fought together for two or three months. Especially foreign engineers spent Christmas on site.
Outotec disc casting machine working scene
Daye Nonferrous's Ausmelt roof top-blowing furnace is Outotec's fifth Australian furnace copper smelting project in China, setting the country's five “most” at the time: the fastest construction, the largest scale, and the largest production index Well, with the lowest energy consumption, the shortest flow, and a global perspective, it also belongs to the world's leading copper smelting project, becoming a nonferrous metal company, Daye Nonferrous Metals, Outotec's three-party model project, classic project, built and put into operation, the same kind at home and abroad Companies have come to visit and study.
Daye Nonferrous and Outotec, seemingly two independent growing trees, have long been connected. As early as 2002, the two sides had their first cooperation. Currently serving as deputy chief engineer of Daye Nonferrous Metals Co., Ltd. Hu Guangsheng, deputy section chief, still remembers clearly the time node of sixteen years ago: 'The two parties began substantive cooperation in 2002. Outotec provided a two-mode 16-die disc casting machine to Daye for smelting. Used by the old system. I was the Chinese general representative of the mechanical part at that time, responsible for the technology docking with Outotec. The process went smoothly. In 2012, the new system was put into production by 300,000 tons and the new Outotec double 18-die disc cast. Before the machine was put into use, this dual 16-die casting machine had been working on a single piece of equipment. Daye's colored anode casting was based on its service. The quality was very reliable. A seemingly simple casting machine, actually a computer controlled, hydraulic system. , Servo, mechanically integrated systems, there are some domestic development, but Outotec's casting model is doing very well.
Synchronize efficiency and quality
In the electrolytic copper plant of Daye Nonferrous Metal Smelting Plant, two Outotec multi-function crane units are under intense operation; in the film stripping machine control room, the operator Xu Wei’s eyes are fixed on the touch screen, and the cathode stripping robot is just as flexible as human hands. Fast, stripping copper cathode from the stainless steel plate at a rate of 500 pieces per hour. Each side of the robotic arm picks up a piece of copper plate, places it, ties it, and forks it out of the building by a forklift. The action is smooth and accurate. 1. The copper cathodes lay neatly, reflecting the golden light in the sun.

With the good foundation of previous cooperation and win-win cooperation, in 2010, Daye Nonferrous Metal's 300,000-tonne electrolysis plant has introduced Outotec's electrolysis-only driving, anode preparation unit, robot cathode stripping unit and electrolysis workshop information management system, and in 2012 In April of this year, it successfully put into normal production.
Secretary of the Party Branch of Electrolysis Second Plant Party Committee and Director of Equipment Ming Jiangyong visited the site with reporters. He explained that multifunctional vehicles can lift both cathodes and anodes at the same time. The work efficiency is high. The accuracy of the spreader positioning can reach 2 mm. Reliable, Robot stripping work is extremely efficient, Daye colored cathode copper quality can reach the standard of high-purity copper, the support and protection of these 'weapons' are indispensable.

Different from the traditional copper electrolysis process, Daye Nonferrous uses a stainless steel cathode plate for cathodic deposition. Mingjiang Yong explained that the stainless steel cathode electrolysis technology and Outotec's equipment cooperate with each other. The biggest feature is that it saves labor costs and has high operating efficiency. The energy consumption is low. He gave the reporter a rough calculation. Compared with the traditional process, Daye Nonferrous Metal's 300,000 tons electrolysis system can save half of the labor, and the electricity consumption is reduced by 30 kilowatts per ton. The product quality is also greatly improved. , The residual rate was reduced by 3%. The reporter saw in the electrolysis workshop that there were only a few workers in the electrolysis workshop at Connaught and only a few inspection staff were working.
When a new process system was first run, some problems would inevitably arise. Outotec's technical staff had been tracking and solving, and Daye Nonferrous’s technical operation team continued to strengthen the maintenance of the equipment. Through the joint efforts of Chinese and foreign technical personnel, Smelting non-ferrous production efficiency continues to increase, 'Daijiang brand' cathode copper with its good quality in the international and domestic markets are selling well.
A win-win situation is the cornerstone of the cooperation between both parties. Daye Nonferrous succeeded in becoming the first echelon and Outotec won praise from the Chinese market. This is based on the strength of equal strength and cooperation between both parties. It is also the mutual exchange of complementary business exchanges, and it is also the cooperation of green development. In the cooperation between the two sides, Daye Nonferrous and Outotec have become winners.
Praise for Chinese and foreign employees
Relying on the top five of China's copper smelting industry, relying on the sixty years of technical experience, Daye's non-ferrous copper smelting technology firmly occupies the top position in China. In the close cooperation of more than ten years, Daye Nonferrous and Outotec's technical team is constantly running in, culture is connected, fate is linked, together to pay, seek common ground while reserving differences.
Copper plate casting operation
After 65 years of baptism, the employees of Daye Nonferrous Metals have demonstrated their responsibility, loyalty, learning, and enterprising core values from time to time. Outotec’s foreign employees have also learned from the Chinese to take the factory as their home, selfless devotion. Valuable quality.
There is a poem in the Book of Songs: No clothes? With Tong Ze, just like the Western proverb No road is long with good company (whether it is partner with Liangyou, Lu Yaojueyuan). Whether it is an installation of an Australian furnace or a potroom Equipment debugging, Daye Nonferrous and Outotec's technical team inseparable from each other, consult each other, to learn together. In order to grab the progress, rush time, Chinese and foreign technical staff in the meeting room to eat a working meal, often at night to wear a star to work overtime.
Before the equipment came into the plant, Daye Nonferrous and Outotec did a good job of training the employees in advance. According to the employees who participated in the training at that time, based on the process model provided by the foreign party, the Chinese operators first learned and simulated on paper. After the keyboard was put into operation, the Chinese and foreign technical teams first carried out the empty car operation, and then carried on the belt material load test. During the few days when the Australian furnace was opened, the Chinese and foreign technical teams gathered at the site, ordered and busy. Without chaos, the organizational nature of state-owned enterprises and the rigor of foreign-funded enterprises were perfectly merged at that moment. In exchange for the success of the one-time commissioning of the furnace, one-time acceptance was accepted and it became a good memory for both parties.
During the cooperation between the two parties, many touching bridges still vividly remembered. In 2012, Daye Nonferrous Metals employees Huang Feng was working with Outotec to operate the electroplating tank. When the electrolysis tank was positioned in three-dimensional coordinates, the fever was very serious. In order to complete the work plan, After he got home, he took some medicine, rested for one night, and worked on the site the next day.
During the installation of the Australian furnace, from the commander to the operator, everyone had been on the spot for three months in a row. The clothes changed were all brought by the family to the factory; the technicians of Outotec's foreigners were also trained like the Chinese employees. Working in the ground, tired to find a corner to rest for a few minutes and then work, Outotec Chinese field engineers are staying at the scene for a few months. The smelter workshop Party branch secretary Yuan Shuangxi recalled: “Otuntai School Engineers are very dedicated, they have rich experience, they are rigorous and they have a good eye. '
After a reporter email contact, far away in the exotic Outotec field service manager Jacob Wood recalled his feelings at the time of the Daye non-ferrous project work, praised and said: 'I was very impressed with the start of the Daye Australia furnace factory Afterwards, according to the pre-established rigorous and scientific trial production plan, Daye's employees achieved the design capacity step by step. Even more rare, the production situation at that time was gradually switched from the Noren colored Nonlander furnace to Aus Maite Furnace, faced with complex production organization and capacity switching, Daye Nonferrous Metals Co., Ltd. divided into multiple steps, carefully debugged, and fully run-in, so the entire plant did not experience major accidental shutdowns and production shutdowns from production to production.
'Yes, at the time it was both the operation of the old system and the opening of the new system, mixed together,' Luo Wei recalled: 'At that time the furnace was installed and commissioned, and the Nolanda furnace was not stopped. Two sets of systems in the whole plant are in operation. Staff deployment is a big problem. Several people are assigned to each class. When the rest of the staff rests, they come to the new system to operate the traineeship. They are tired, but everyone is very motivated. '
Two national cultural homologs
As a global company from Finland, Outotec upholds the corporate mission of 'sustainable use of the natural resources of the planet', upholds the core values of 'committed to sustainable development', and works with its peers in the pursuit of excellence in leading technologies to achieve cooperation. A win-win situation. For Daye Nonferrous Metals, it has a copper axe culture that is 'hardened and developed for development'. Although the two sides have different nationalities and different skin colors, the green concept of sustainable development and harmonious and win-win culture are the same. Melt together to form the largest value of the common divisor.
Liao Chongan, chief engineer of Daye Nonferrous Metals Smelting, said in an interview: 'In the process of installing the cathode stripping unit, some of our viewpoints were also absorbed by Outotec, constantly optimizing. Outotec's core is advanced equipment, which is the basis; It is conditional that the two are interdependent and indispensable.'
State-problem identification; Creativity-cause analysis; Bank-organization practice; Standard-setting standards. This four-character working method is a guide for Daye Nonferrous Metals Smelter employees to create innovative results. Melting workshop is both a non-ferrous company's innovative work for employees. Room, is also Huangshi Technician Innovation Demonstration Studio, Hubei Skills Talents Workstation, Rows of Trophy Cups, medals are placed in a prominent position in the window, revealing the core values of responsibility, loyalty, learning, and enterprising.
During the interview, Liu Wanglin, deputy director of the Daye Nonferrous Enterprise Cultural Center, handed over two volumes to the reporter. One is a cultural story, and the other is a palm-sized cultural handbook. Turning over the 71-page booklet, it explains in detail the Daye colored 'Oe Culture' : The Navajo Stream condenses into a powerful arteries; the essence of Poly-Qianshan is hammered into a cluster of golden brands... Innovative products, innovative technologies, innovative management, innovative mechanisms, and innovation are never ending.
Bringing glory with quality, adding glory to the society. Daye Nonferrous’s spirit of pioneering and innovation, pursuing excellence in cultural heritage, and building first-class beliefs are not formed overnight, but have been accumulated and precipitated after several years. The current in-service technology engineer of Outotec Shanghai, Kong Lingqi, said: “Yasteel's non-ferrous technical strength and corporate culture are first-rate. Outotec has also learned a lot in the process of cooperation with such customers, such as Outotec. The field service personnel saw Daye Nonferrous Clerk employees working so hard. They also adjusted the on-site working hours from 8 hours a day to 12 hours a day. In addition, Outotec has always advocated green, energy-saving and environmentally friendly, with the best Products and technologies serve the world. Cooperation with Daye Nonferrous Metals is a perfect example of the cooperation between the two parties. It is also an important window of cooperation between China and Finland in the non-ferrous metal industry.

Commitment to a common belief and mutual observance of a responsibility. Daye Nonferrous Metals and Outotec are jointly responsible for green development, social responsibility for saving energy and reducing consumption, and working together to continuously explore new products and new processes. The largest Ausmelt top-blowing furnace project in operation, the copper smelting system jointly constructed by Daye Nonferrous Metals and Outotec demonstrated many features such as strong raw material adaptability, short process flow, and high working efficiency. Water to bear fruit.
In recent years, in addition to Daye Nonferrous Metals, Outotec has also cooperated closely with the China Nonferrous Metal Mining Group-funded enterprises such as Fushun Hongtoushan Copper Mine and Zhongshen (Ningxia) Dongfang Group in China, and has captured the attention of China Nonferrous Metals Mining Group. Under the leadership of resources, internationalization, and high-end technology, Outotec has developed technologies and equipments in cooperation with China Nonferrous Metal Mining Group in countries including Kazakhstan, Zambia, Congo (DRC), India and other countries and regions along the Belt and Road. deep cooperation.

She said: 'Outotec's products start from the procurement of raw materials and end with the delivery of customers. The entire process always focuses on environmental protection, safety, and occupational health. Selecting Outotec's products represents a responsible attitude towards the environment, safety, and occupational health. In recent years, with China's environmental protection and increasingly stringent safety requirements, the scope of cooperation between Outotec and Chinese companies will continue to increase. Expand. '
On the morning of April 5, 2017, Chinese President Xi Jinping visited Finland and met with Finland’s President Nini Stowe to meet with reporters. Xi Jinping said that the Finnish proverb says that “no one will have no way to open up,” and Chinese people often talk about artificial things. We must continue to uphold the spirit of pioneering and innovating and dare to be ahead of others, and open up a new type of partnership for the future of the two countries to create a better tomorrow.
As large as a country and a nation, and as small as a company, it is only through continuous reform and innovation that it actively expands its opening up, constantly conquering itself, and surpassing itself, to turn once-unfamiliar dream blueprints into accessible construction drawings. In cooperation with Outotec, we are committed to openness, mutual learning, mutual benefit and mutual benefit. We both focus on high-quality development and work together to advance into world-class companies. We must try our best to achieve the same goals.
