Abstract

Tests were performed on the continuous 250-2 light-section mill at the EVRAZ ZSMK combine to study the effect of the deformation regimes on the healability of surface defects on semifinished products. It was confirmed experimentally that increasing the degree of similarity between the pass and the cross-sectional shape of the initial semifinished product increases the healability of the defects. A new pass system was developed for the rolls in the roughing-stand group of the 250-2 mill. Introduction of the new system has increased usable output 3% by reducing the incidence of rejections due to surface defects.
