A new technology for measuring the thickness of non-ferrous metals strips has been developed by ABB. It is based on pulsed magnetic fields,and therefore features a unique combination, i.e. the measurement is contact free and measuring results are independent of material properties. Tests in a copper rolling mill have shown the

In the manufacturing process of hot strip continuous rolling, it is one of key factors to ensure stability rolling and better quality of strip, to keep the relatively invariable strip tension between two stands. Draft compensation was adopted, which takes the initiative to compensate roller speed, in order to decrease the coupling effect of automatic gauge control subsystem, …

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 ...

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll …
