摘要：PURPOSE:To obtain the cold rolled steel plate holding a high surface luster by performing a chrome plating in specified thickness on the surface after finishing the surface of a work roll by grinding in a specific surface roughness. CONSTITUTION:A chrome plating in 10-20mum thickness is executed on the surface of the outer periphery subjected to a grinding in <=0.10mum surface roughness by an electroplating method and an ordinary steel is cold-rolled by using the chrome plating roll whose chrome plated face is ground <= equiv. to the surface roughness prior to plating by buff. The surface defects of a rolled steel plate of a linear flaw, oil bit, etc., are thus reduced and the rolled steel plate having a high surface luster is obtd.
