introduction
The steel rolling site is often accompanied by various harsh conditions such as high temperature, water fog, dust, etc. The outer diameter of the steel is an important indicator. Rolling steel is not only poor in environment but also very fast in production. It is tested after production is completed after cooling. This method is accompanied by the production of a large number of unsatisfactory rolling stocks. Therefore, on-line inspection is one of the urgent problems to be solved in rolling steel. To solve this problem, it is necessary to solve various basic problems such as high speed, harsh environment, and high temperature detection. And the diameter measuring instrument, which can perform statistical analysis on the measurement data, will be more suitable for the production site, so that the staff can understand the overall production status and make adjustments.
1, round steel diameter measuring instrument
The principle of photoelectric measurement principle is the basic principle of the hot-rolled round steel diameter measuring instrument. The size measurement of the hot-rolled round steel is performed with eight sets of photoelectric measuring heads. Each set of probes can measure the diameter of the wire in one direction. Through the calculation and processing of the measurement data, the instrument can obtain ellipticity dimensions, wire diameters in the same cross section in eight directions, maximum diameter, minimum diameter, average diameter, and other information.
The round gauge measuring instrument system is a complete set of equipment integrating optics, machinery, electronic circuits, communication and computer software technology. The set of equipment mainly consists of diameter measuring instrument, main control cabinet, alarm unit, optical cable communication unit, on-site LED display screen. , High-pressure centrifugal fan, spare car and other components.
2, the diameter gauge software system
The round steel diameter measuring instrument is a high-precision wire diameter size testing equipment. In order to realize a variety of information display, a software system was developed for the round steel diameter measuring instrument.
The above figure is the main interface of the software system. It can display the basic data of the measured hot-rolled round steel. The diameter, maximum diameter, minimum diameter, average diameter, and ovality of the eight groups of probes can be displayed. The basic data of the round bar, product type, nominal diameter value, allow positive tolerances, allow negative tolerances, thermal expansion coefficient. Also self-test, display basic information such as circuit board temperature.
In the right part of the software system, you can see two images, which show the cross-section and the trend graph respectively. The image shows the cross-section of the tested round steel more intuitively.
On the menu bar of the software display system, you can see two buttons, which are the wave diagram and the defect map. The following two diagrams are the wave diagram display interface and the defect diagram display interface respectively.
The fluctuating graph is mainly used to view the dimensional fluctuations of the tested round steel. The horizontal axis of the oscillogram is represented by time, and the vertical axis indicates the contour size (outside diameter) measured by the probe. From the figure, the entire root can be seen. Direction of change in outside diameter dimensions. When the mouse is pointed at the corresponding time position (left-click), a vertical cursor appears, allowing observation of the corresponding diameter condition.
The defect map is mainly for observing the type of out-of-tolerance. In the measurement state, the over-difference type of the eight-way measurement value can be observed, such as overshoot, undershoot, ellipticity, etc. The horizontal axis of the defect map is represented by time, vertical axis It means that the type of wire diameter measured by the probe can be very image in the rolling field, and the wire can be obtained in a timely manner. The distribution of rolling defects of the wire rod, especially the head and tail defects of the rolling material, and its continuation length, To moderately adjust the rolling process configuration.
The round gauge has a data storage function. Historical data can be saved for more than one year. Historical data query interface can see past measurement data. Viewing data can be accurate to second. The query interface displays the main interface diagram, which can be easily observed. In addition, historical data can be exported in the form of an Excel spreadsheet, as shown in the following figure.
The exported table can facilitate the data sorting, observation, can see the eight-direction diameter, the largest diameter, the smallest diameter, the ellipticity of the size, can display the diameter of the excess and ellipticity of the excess.
Conclusion
The round steel diameter measuring instrument is equipped with a professionally developed software system, which can effectively achieve high-precision wire diameter size detection, and can perform statistical analysis of data, so as to have an overall grasp of the rolled round steel, which is likely to cause product overshoot. Position, improve production process, ensure its production within the specified range, improve quality and increase efficiency.
