The daily working efficiency of the rolling mill is significantly influenced by environmental factors, primarily temperature and humidity. To improve the efficiency of the rolling mill, strict requirements are placed on humidity, especially at the narrow exit of the reheating furnace.

The main factors affecting the fluctuation of rolled product thickness come from both the workpiece and the rolling mill in the steel production process. On the rolling mill side, factors influencing plate thickness primarily include the eccentricity of supporting rolls. This eccentricity results in periodic variations in the roll gap with each revolution of the rolls. Additionally,
