Rolling Mills | Industrial Efficiency Technology & Measures

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold ...

Shape-control characteristics of six-high mill with roll ...

To improve the stability of the six-high cold rolling mill, the roll offset method is often used. This paper uses ABAQUS finite element software to establish the rolls-strip coupling model. The study analyzes typical roll systems with different roll offsets to determine the effect of different roll offsets on the shape-control characteristics of the six-high cold rolling mill.
