introduction
Rolling steel is often accompanied by various harsh conditions such as high temperature, water mist, dust, etc. The outer diameter of steel is an important indicator. The rolling steel is not only poor in environment, but also has a very fast production speed. It is tested after cooling according to the previous production. The method is accompanied by the production of a large number of unqualified rolled materials. Therefore, on-line testing is one of the urgent problems that need to be solved in rolling steel. Therefore, it is necessary to solve various basic problems such as high speed, harsh environment and high temperature detection. . And the caliper that can perform statistical analysis on the measured data during rolling inspection will be more suitable for the production site, so that the staff can understand the overall production status and make adjustments.
1, round steel caliper
The hot-rolled round steel caliper is based on the principle of photoelectric measurement. Eight sets of photoelectric probes are used to measure the size of hot-rolled round steel. Each set of probes can measure the diameter of the wire in one direction. By calculating the measurement data, the instrument can obtain various information such as the ellipticity dimension, the wire diameter size value, the maximum diameter, the minimum diameter, and the average diameter in the eight directions of the same section.
The round steel caliper system is a complete set of equipment integrating optical, mechanical, electronic circuits, communication and computer software technology. The set of equipment is mainly composed of caliper, main control cabinet, alarm unit, optical cable communication unit, on-site LED display, high-pressure centrifugal fan, spare trolley and so on.
2, round steel caliper software system
The round steel caliper is a high-precision wire diameter measuring device. In order to realize the display of various information, a software system has been developed for the round steel caliper.
The above picture is the main interface of the software system. It can display the basic data of the measured hot-rolled round steel. The diameter values, maximum diameter, minimum diameter, average diameter and ellipticity of the eight sets of probes can be displayed. Basic data for round steel, product model, nominal diameter value, allowable positive tolerance, allowable negative tolerance, thermal expansion coefficient. In addition, it can also self-check and display basic information such as board temperature.
In the right half of the software system, you can see two images, which are the cross-section and trend graph. More vivid and more intuitive display of the cross-sectional profile of the measured round steel.
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.
The fluctuation diagram is mainly used to view the dimensional fluctuation of the measured round steel. The horizontal axis of the waveform diagram is expressed by time, and the vertical axis represents the contour size (outer diameter) measured by the probe. From the figure, the whole root can be seen. The trend of the direction of the outer diameter of the direction. When the mouse points to the corresponding time position (left click), a vertical cursor appears, and the corresponding diameter condition can be observed.
The defect map is mainly for observing the type of over-difference. In the measurement state, the type of over-range of the eight-way measurement value can be observed, such as the super-difference, the lower tolerance, and the ellipticality. The horizontal axis of the defect map is expressed by time, and the vertical axis represents the type of wire diameter error measured by the probe. The rolling defect distribution of the wire and the bar can be obtained in a timely and timely manner at the rolling site, especially for the rolled material. The characteristics of the head and tail defects, and their continuation length, to moderately adjust the rolling process configuration.
The round steel caliper has data storage function, the historical data can be saved for more than one year, the historical data query interface can see the previous measurement data, the viewing data can be accurate to the second, and the query interface displays the main interface map, which is convenient for observation. . In addition, historical data can be exported in Excel form, as shown in the following figure.
The exported table can facilitate the data sorting and observation. It can see the size of the eight-direction diameter, the largest diameter, the smallest diameter, and the ellipticity, and can display the diameter tolerance and the ellipticity.
Conclusion
The round steel caliper is equipped with a professionally developed software system, which can effectively realize 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 easy to cause the product to be out of tolerance. Position, improve production process, ensure that it is produced within the specified range, improve quality and improve efficiency.
