Abstract

PURPOSE: To prevent the heat scratch, and to improve the production efficiency, by limiting the range of average surface roughness of the work roll serving in the cold rolling work.
CONSTITUTION: At cold rolling the steel strip, the average surface roughness of the work roll is limited in a range 0.2W0.4. Hereby, the amount of rolling mill oil attracted to the biting zone of the work rolls becomes optimum, so that the heat scratch does not generate. Meanwhile, at cold rolling a steel grade of large deformation resistance, the work roll of average surface roughness ranging from 0.2W0.4 and the intermediate roll of average surface roughness 1W7 times that of the work roll, are used together with. Hereby, the thickness of oil film on the surface of the work roll becomes optimum, so that the heat scratch does not generate.
