PURPOSE:To make the abrasion of rolling rolls uniform by moving the position where a rolling material is to be bitten in the rolling rolls in the width direction of the rolls at every rolling material. CONSTITUTION:After the first rolling material 1 is rolled, the next material 1 is rolled with a change in the rate of shifting of a side guide 9 by the command from a strip shift controller 14 calculated beforehand. The materal 1 after this is rolled with the similar change in the guide 9 in the rolling width direction. In this way, at every change of the materials 1, the rolling positions in the barrel direction of the rolling rolls change and therefore the abrasion of rolling rolls 2a, 2b is made uniform. |
