A BASIC UNDERSTANDING OF THE MECHANICS OF

2003-10-15  Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schröder July 2003 K. H.

ROLL SPEED SET-UP IN HOT STRIP FINISHING ROLLING

2007-1-1  Hot strip finishing mill is initially set up with rolling conditions such as roll speed, roll gap, and cooling pattern obtained by a set-up model. To improve the accuracy of initial roll speed setting for a 7–stand finishing mill, an equation for predicting forward slip and a compensation method for initial roll speed setting were proposed
