Abstract: PURPOSE:To prevent problems of biting and passing-through of a rolled stock to suppress the flaws on a inner surface and to improve the rolling efficiency by measuring the biting time and the passing-through of the rolled stock time to obtain both slip ratios based on the measured values, comparing with a reference slip ratio and controlling a set value of rolling for the next material to make the difference to be zero. CONSTITUTION:As to signals of a load cell 43, the time from a rise time to a reach time reaching a load value of a load level setting derive 51 for the rolling is denoted as the biting time t1 and stored in an arithmetic and storage device 54. More, from the reaching time of the output of the load cell to the load value of the rolling load level setting device 51 to the time of departing the rolling material from the rolls is denoted as the passing-through time t2 to store in the same device 54. Then, the biting time t1 and the passing-through time t2 are given to an arithmetic and control device 55 to calculate the slip rate at biting and passing-through time. After that, comparing with the slip rate capable of boring by a reference setting device 58, the next roll setting value is controlled when both slip rates are under the reference value, the difference between the slip rate and the reference slip rate is to become zero, and when the both sides or one side of the slip rates are over the reference value, the difference between the higher slip rate and reference value is to become zero.
