cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. in this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...

High hardening of the steel, which is caused by martensitic transformation through cold forming, leads to significant local elastic roll deformation (flattening). The rolling strain-hardened steel requires higher forces and torques, result in high force. Roll flattening can be reduced using rolls made a material with significantly modulus elasticity. suitability ceramic materials for modern hot...

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 ...

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...
