Abstract

PURPOSE:To prevent the generation of rolling troubles by measuring the coeffts. of friction of rolls with measuring devices for coeffts. of friction of rolls provided to respective rolling stands at all times, and regulating the coefft. values from the biting of the material to be rolled until the end of rolling in accordance materials and rolling conditions. CONSTITUTION:In hot rolling wherein oil lubricated rolling is effected, the coeffts. of friction of respective work rolls are measured at all times with measuring devices 1 for coeffts. of friction of work rolls 2 provided in respective rolling stands. When the coeffts. of friction on the surfaces of the rolls 2 are going to device from the prescribed range determined beforehand in accordance with the quality of a material 7 to be rolled and rolling conditions during rolling, the increase or decrease for the supply rate of lubricating oils is commanded from an oil flow rate command circuit 19 to an oil flow rate control loop circuit 18 in accordance with the measured values of the devices 1. In accordance with these commands, the circuit 18 operates an oil flow rate control valve 14, thereby returning the coeffts. of friction to adequate values.
