Compared with the rolling conditions of mild steels, those high tensile strength steels (HTSS) are very different, because their flow stress. Dimensional accuracy thickness at top end industrially rolled HTSS is lower, compared steel. This predicted force for not accurate sufficiently. problem due to only used stress model, but also theory model. If standard Hill’s equation and Bland Ford’s for...

The analysis of the ring rolling machine capabilities in providing increased accuracy blanks is performed. necessity operator’s participation controlling to achieve required even with full automation manufacturing process noted. cooling circular after ensure has been To eliminate ovality low rigidity mill it proposed use technology their controlled and stabilization. sequence thermal strain con...

Compared with other forming processes, Pilger cold rolling exhibits unique process characteristics and a simple production method, making it highly advantageous in terms of high-precision, high-strength, poor-plasticity alloys. Among them, the design parameters mill play significant role results, key being hole opening angle θ gap ΔK. In this study, numerical simulation model for an AZ31B magne...

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 ...
