In cold rolling of silicon steel strip, edge drop directly affects the side cutting and yield steel. To improve in process, a multi-stand coordinated control strategy model based on multi-objective optimization are proposed. The first step is to analyze influence each stand work roll shifting (WRS) through finite element (FEM), then determine effectiveness actuator. Meanwhile, fitting proposed ...

Dimensional control of the work-piece in steel industry is of important interest. The main aspects in overcoming the thickness control are variations in material strength due to variations in chemical composition, work-piece temperature, reduction and the strain rate applied to the work-piece. In this paper based on the main parameters affecting the rolling force an attempt been made to give a ...

Abstract. The technological process of manufacturing cold-rolled strip with a thickness 0.5-1.5 mm from high-strength steel grades on cold rolling mills can consist 2 or even 3 operating cycles "cold - intermediate annealing". This is due to significant hardening such steels during and, as result, limitations the maximum allowable forces. Each additional cycle annealing" significantly increases...

Strip rolling is a typical manufacturing process, in which conventional control approaches are widely applied. Development of the algorithms requires mathematical expression process by means ?rst principles or empirical models. However, it difficult to upgrade response ever-changing requirements and environmental conditions because domain knowledge engineering, mechanical material science requi...
