Abstract

PURPOSE: To obtain better rolled products by optionally changing the shape of the azial line of intermediate roll in the direction of plate flow by supporting before and after the shell portion of intermediate roll by means of a desired method to obtain a desired roll crown of work roll.
CONSTITUTION: The support rolls 20 and 21, which rotate in contact with the intermediate roll 2, are provided before and after the intermediate roll 2. When a fixed roll crown is given to the above and below work roll 1, the support rolls 20 and 21 are moved to change the supporting positions and the intermediate roll chock 5 is then moved in the direction parallel with the flow of plate. Thus, the intermediate roll 2 is bent toward the direction parallel with the flow of plate and the vertical space between the work roll 1 and the intermediate roll 2 is changed with the bent shape of the intermediate roll 2, so that the roll crown of the work roll 1 is changed into a desired shape. This method enables the shape control of plate to be performed easily
