Abstract
PURPOSE: To make easire rolling operation by lessening impact to roll by making feeding speed slower by detecting material to be rolled before the rolls or making it faster by a roll interlocking detection signal.
CONSTITUTION: The steel ingot 4 is fed in the arrow mark direction 5 by interlocking the rollers 3a and 3b with the main roller 1 by the command of controller. When the steel ingot 4 reaches the position of the detector 7 at the time T-2, the decelerating relay is operated and the main roll 1 is decelerated at the time T-1 to lower the speed of steel ingot. And, at the time T0, the tip 4a of steel ingot is put into the main roll 1, whereupon rolling torque rises up at the time T0 but with less impact and peak torque smaller than the firm motor max. torque. And, the load shell 9 is operated, the decelerating relay is tamed, the steel ingot 4 is rolled with increased speed from the time T0 to the time T1, and odd pass is completed at the time T0 and stopped at the time T3 to complete the rolling in the arrow mark direction 5. The same is ture of the arrow mark direction 6. Thus, impact to rolls can be greatly reduced.
