On December 19, MCC's complete set of seamless steel pipe continuous rolling mill 89 was put into operation in Henan Linzhou Fengbao Pipe Industry Co., Ltd. The project adopted the world's first set of the smallest diameter (89mm) Roller six rack hot rolling mill, the main technical indicators have reached the world advanced level.
The world's first 89mm three-roller tandem pipe production line was put into operation at MCC CCID
Fengbao project is the world's first three-roller hot strip production line specialized in the production of small-diameter seamless steel tubes. The product specifications range from 32mm to 89mm with wall thickness of 3mm to 12mm and designed annual output of 200,000 tons to produce axle, steering shaft , Bearing tubes and other high-quality lightweight materials mainly for nuclear power, petroleum industry supporting the supply of high-end seamless steel tubes.
MCC CCID takes full advantage of the multi-specialty system integration and core equipment manufacturing capabilities in the field of steel engineering, independently develops the rolling technology and core equipment, and successfully applies the three-roll and six-stand hot rolling mill to small caliber Seamless steel pipe production, using the world's most advanced lateral roll-change three-roll six-rack tube mill and 28-frame tension reducer, equipped with a complete process control model, through the high response hydraulic servo roll gap control System and highly automated control system to realize the "sharpening rolling" of continuous rolling mill, the wall thickness control of tension reducer and CEC control function. The high-speed data acquisition system and monitoring system independently developed by MCC, The production process of visual monitoring and digital analysis, production line technology, control technology has reached the world's leading level.

The project also innovated the production process and realized the 'heat substitution cooling' for the production of small-diameter seamless steel pipes, which reduced the energy consumption, metal consumption and environmental pollution of the traditional cold-rolled / cold-drawn processes and laid the foundation for the comprehensive application in China Based and provide technical assurance for the steel industry to green manufacturing, intelligent manufacturing transformation and upgrading set a benchmark.
Since October 1, 2017, when the heat load test has been successfully carried out, the project has been continuously optimized and optimized during the trial production period and has achieved continuous, steady and high-paced flexible production in two months and gradually brought into play the high quality , High efficiency, high yield and other advantages, to fill the domestic high-end small-diameter hot-rolled seamless steel pipe industry blank.
