Research on the Influence of Hot Strip Shape to Ribbing Defect

Abstract:

Aim at solving the problem of ribbing defect is found on cold rolling strips which is caused by bad hot strip shape, analyze the reason from the hot rolling process, and study out that there are some reasons such as uneven wear of rolls can lead to ribbing defect. Roll contour, roll shifting model, rolling plan were optimized and got a geart effect: the hot strip shape being better, the production being more stable, the ratio of ribbing defect decreasing obviously (from 2.2% to 0.3%). The quality of their product has been improved a lot.
