Abstract (en)

[origin: EP0469483A2] Disclosed herein is a process for coiler drum alternation in incessant hot rolling in which continual finish hot rolling of rough-rolled sheet bars united on the entry side of a finishing hot rolling mill is carried out by tilting upper and lower tiltable pinch rolls (10,12) disposed on the exit side of a shear (80) on the downstream of the finishing mill, thereby changing the traveling direction of the steel strip (100) so that a leading end formed upon cutting the strip will be directed toward the next coiler drum (30b) to be used, and thereafter cutting the strip. This process enables an easy and assured alternation of coiler drums (30), thereby contributing to increases in the speed and efficiency of incessant hot rolling. <IMAGE>
