Abstract

PURPOSE: To make the surface conditions of front and back surfaces of a rolled product uniform or dissimilar to each other as a result of an intended effect, by changing the bending angle for a strip approaching to rolling rolls.
CONSTITUTION: At carrying out a rolling work for a strip S with a couple of rolling rolls having diameters different from each other, if the surface conditions of front and back surfaces of a rolled product are required to be similar to each other, the strip S is bent to the small diameter roll 1 side in order to adjust the angle of bite at the roll bite so as to make the angle of bite θL on the large diameter roll 2 side substantially equal to the angle bite θS on the small diameter roll 1 side. On the other hand, when it is intended to make the surface conditions such as the luster, roughness, etc., of the front and back surface of a rolled strip product dissimilar to each other, the angles of bite θS, θL for the strip S by the rolling rolls 1, 2 are changed. For the purpose of changing these angles of bite, a deflector roll 3 is installed on the feed-in side of the rolling rolls 1, 2 and this deflector roll 3 is vertically dislocated by an elevator such as a hydraulic cylinder, etc.
