Abstract
The purpose of the study is to study the possibility of controlling the dimensions of rolled products using indirect methods of assessing changes in the thickness of rolled products. For this purpose, a study was carried out on the measurement of the length of rolled products using a length meter, which is based on the principle of measuring the length of the rolled products by rotation of the rolls. Comparison of the measurement results with the actual length of the rolled product confirmed the possibility of using this device for measuring the length of the rolled product in the flow. During the study of the rolling process, the length of the rolls after the finishing stand, the thickness of the rolling stock, the temperature of the rolls before the finishing stand, and the motor current of the main drive of the finishing stand were measured. The measured results showed a decrease in the length of the rolled product and the motor current, which is associated with the wear of the fabric bearings and gauges of the rolls, which leads to an increase in the thickness of the rolled product. Calculating the average values of rolled length, motor current, and rolled temperature makes it possible to evaluate the change in rolled thickness due to the wear of bearings and roll gauges and to compensate for its influence on the dimensions of rolled products in a timely manner.
