Abstract

PURPOSE: To high accurately control the tension in a hot-lubricated rolling work, by correcting a torque arm correspondingly to a change in the oil feed rate, at changing the feed rate of the lubricant oil during the rolling work is operated by a tandem hot-rolling mill.
CONSTITUTION: A material 1 is rolled while the lubricant oil is fed at a suitable timing from a lubricator 400; hereupon, the rolling load Pi detected by a load cell 5, the electric current Ii of a motor 4, its voltage Vi and rotational speed ωi, and the roll gap Si are inputted to a tension detector 200 included in a tension controller 100. The detector 200 computes the rolling torque and the torque arm from these inputted data, and obtains the tension value. When the feed rate of the lubricant oil from the lubricator 400 is to be changed, the torque arm to be used in computing the tension is corrected correspondingly to the changing rate of the oil feed rate; hereby, the tension can be computed with high accuracy. A controller 300 decides the corrective amount of the rotational speed of the motor 4 of each stand required in controlling the tension detected by the detector 200 to a preset aim value, and corrects the rotational speed of the motor 4 of each stand.
