The control strategy of multi-stand work roll bending forces and shifting stroke on the crown for the UVC mill is established, to meet the PCFC requirements of wide electrical steel in the HSMs. ... The WRB function of the UVC mill is used more reasonably within the limit, which can control the strip quality and allow full play to the crown ...

Roll wear in a hot strip mill (HSM) is a detrimental process, which progressively worsens the rolls. This necessitates replacement of the rolls after rolling a number of strips. Roll wear adversely

At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacing any of the material – meaning material is always displaced and never lost. By design and …

What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar …

can be minimized by modifying the roll gap with various control functions, such as roll-bending and -skewing, shifting of rolls, cooling patterns and eccentric positioning control for multi-roll stands. The influence of each separate type of control action is defined by evaluated action curves. A least square fit of these action curves to the

components were combined for safe tandem mill roll-ing in the X-Roll Guide FM system. All mill stands are equipped with the RAC system similar to the one at the roughing mill stand. For mill stands with hydraulic work roll shifting systems, the thrust force compensation (TFC)4 can be added to compensate
