Plate and strip production plays an important role in the national economy. Plate thickness and shape are the main indicators of product accuracy, and always take thickness accuracy as the main goal, so as to improve the quality of products. With the increase of production and demand of cold-rolled strip, the quality and thickness of cold-rolled strip are required more and more. How to minimize the deviation of strip thickness and ensure the uniformity of strip thickness is an important problem in strip rolling.<br>The mathematical model technology of cold rolling production is the key technology of cold rolling production. The main purpose of improving product quality in cold continuous rolling is to control the thickness accuracy of strip steel. The thickness setting adopts mathematical models such as rolling force model and spring equation to set the high precision of rolling, which is of great significance to improve the thickness accuracy and product quality of plate and strip. The thickness setting and self-adaptive have gradually become an important part of thickness precision control. In order to ensure the product quality requirements and product requirements, it is necessary to analyze the factors that affect the thickness accuracy of the plate and strip. According to the process characteristics of the cold continuous rolling of the strip, the appropriate mathematical models such as rolling pressure model, deformation resistance model and forward slip model are selected to reduce the thickness deviation and ensure the thickness uniformity, so as to realize the thickness accuracy of the rolled plate and strip within the thickness tolerance of the required plate and strip Within the allowable accuracy range.<br>In this paper, through the analysis and design of the mathematical model, the thickness of ST12 steel products is controlled for five stands of cold tandem rolling. The aim is to reduce the thickness deviation, ensure the thickness uniformity, improve the thickness accuracy and meet the production requirements.<br>
