Abstr act According to the requirements of subsequent production processes for producing
high-end cold rolled steel plate with electrodeposited chromium and the existing cold rolled
equipment in Anstee l, the effect of such technologies as the roughness configuration technology for
the rolls of a rolling mill, the roll-grinding technology and the dry temper technology on the
surface roughness of a steel plate was studied. Based on the study, the surface roughness reache
up to the value of 0.1 wm while the surface gloss was 400 after finishing the temper rolling
process. And what's more the surface reflection highlight met the requirements required by the
steel plate. So the high-end cold rolled black plate with electrodeposited chromium was developed
successfully in Ansteel
