METHOD FOR SYSTEMATICALLY ADJUSTING THE SURFACE STRUCTURE OF ROLLING STOCK DURING COLD REROLLING TEMPER ROLLING MILLS

摘要

No. 1352/CHENP/2a05 A B S I R A C T METHOD FOR SYSTEMATICALLY AD,n;STING THE SURFACE STRUCTURE OF ROLLING STOCK DURING COLD REKOLLLNG TEMPER ROLLING MrLLS fhe present invention relates to a method for specincally adjusting the surface structure of rolling stock (3) during cold rolling in skin pass mills. The aim of the invention is to panially transfer the surface structure of the working roll (2) onto the rolling stock (3). To this end, the change of roughness ot' the rolling stock (3) in the rolling process of a single or multiple-stand, preferably two-stand skin pass mill is calculated in an optimization calculation in which the rolling parameters are varied according to the mill capacity using a triboiogical model that mathcmalically describes the friction conditions in the roll gap (1). The results obtained are then used to readjust at least a part of the rolling parameters used for calculation. (tig 1-Fig4)
