Abstract

DC60 This invention provides a temper rolling method for temper rolling a steel plate to improve the brightness of the steel plate. Without increasing equipment and production requirements, the method used steel plates containing 0.012 wt% or less of carbon (C) and a temper rolling mill, where at least Roller on side stand The top face is a scratch bright roll with a surface roughness (Ra) of 1.2 microns or less, and at least the last stand roller. It is a bright roll with a surface roughness (Ra) of 0.5 microns or less.This invention provides a temper rolling method for temper rolling, steel plates. plate) to improve the brightness of the steel plate.
