Abstract

PURPOSE: In the case of transferring a material to be rolled by increasing the peripheral speed of a roll more than the actual speed of the material to be rolled, to lower the peripheral speed of the roller after the passage of the proximal end of the material to be rolled less than that of the roller while said material is passing, thereby to prevent the occurrence of any rippling phenomenon and that of any scratch.
CONSTITUTION: Before a material 12 to be rolled reaches a final finishing rolling mill 10, hot run tables 18a through 18d have all the peripheral speed of rolls 15 to 20% faster than the speed of the material 12 to be rolled. When the rolled material 12 leaves the final finishing rolling mill 10, passing through the hot run table 18a, and its proximal end is detected by a rolled material proximal end detector 20, a signal from the detector 20 is sent to a computer 26. The computer 26 controls successively rotation controllers 24a through 24d based on the calculated values of roll peripheral speeds of hot run tables 18a through 18d set by a main motor 32 of the rolling mill 10 and a speed ratio setter 28, and increases the roll peripheral speeds of the tables after the proximal end of the rolled material 12 has passed by 5 to 15% of the actual speed of the rolled material 12.
