METHOD FOR RESTRAINING FLOW BUCKLE AT THE TIME OF TEMPER ROLLING

摘要

PURPOSE:To restrain the generation of flow buckle and to stably obtain product excellent in shape quality by bringing a bender roll close to a work roll by pushing out the bender roll in an oblique direction and rolling by increasing the pass line angle of a material to be rolled. CONSTITUTION:At the time of the temper rolling of stainless steel sheet, the bender roll 1 of which the pushing-out direction is inclined to the side of the work rolls 3 of a temper rolling mill 2 is arranged on the outlet side of the temper rolling mill. The bender roll 1 is brought close to the work roll 3 by pushing it out in the oblique direction and the material 4 to be rolled is rolled by increasing its pass line angle (an angle of contact on the outlet side of work roll). In this way, flow buckle can be stably restrained.
