ENERGY SAVINGS - TMEIC

In hot strip rolling mills, high pressure water jets are used to remove scale from the steel bars just before they enter the rolling mill. The descaler pump runs at a constant speed, and the high pressure water is bypassed to the water pit when no bar is present. Running the pump at a constant speed wastes energy and water and heavy

Hot Strip Mill - an overview | ScienceDirect Topics

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 force ...
