Abstract

PURPOSE:To eliminate the difference in the surface roughness between both surfaces of a strip and to improve quality by adding one piece of work roll further to a tri-star rolling mill having 3-point screw down points thereby forming the 4th screw down point. CONSTITUTION:The 4th outside circumference work roll 6 is disposed in the position having a center connecting the respective centers of a central work roll 1 and the 3rd outside circumference work rolls 2C forming the 3rd screw down point 4C. The strip past the point 4C travels 1/2 around the circumference of the rolls 2C and passes through the 4th screw down point 4d formed between the rolls 2C and the roll 6. Since the surface of a strip in contact with the roll 6 at the point 4d is the surface on the roll 1 side and therefore it is easily possible to bring the surface roughness of the strip rolled thrice on the roll 1 side closer to the surface roughness of the surface rolled by the rolls 2C.
