[0002] When the tension roller of the continuous annealing and tempering machine slips, there will be relative sliding between the strip steel and the roller, which will seriously affect the quality of the strip steel surface, and will also cause the rolling force, tension and elongation of the temper mill The fluctuation affects the stable operation of the tempering machine
[0003] At present, there is a serious hysteresis in judging the slipping phenomenon of the tension roller of the skin pass mill, and the determination of the position and time of the tension roller slipping lacks effective technical methods and means, and it is difficult to judge the slipping position and time of the tension roller in time

The invention provides a method and device for judging the slipping positions and time of tension rollers of a levelling machine. The method comprises the steps that an inlet tension roller unit and an outlet tension roller unit are arranged on the front portion and the back portion of the levelling machine respectively; the torque of all the tension rollers in the inlet tension roller unit is controlled; the torque of all the tension rollers in the outlet tension roller unit is controlled; when the torque of all the tension rollers in the inlet tension roller unit changes, the changing time is recorded; and when the torque of all the tension rollers in the outlet tension roller unit changes, the changing time is recorded. According to the method and device for judging the slipping positions and time of the tension rollers of the levelling machine, the slipping occurrence time and the slipping elimination time are recorded, therefore, the total slipping time can be analyzed, workers onthe site can judge the slipping positions of strip steel and the tension rollers according to the data, then the strip steel damaged due to slipping can be quickly found, and the very good practicability is achieved.
Description
technical field [0001] The invention relates to the technical field of cold rolling and steel rolling, in particular to a method and a device for judging the slipping position and time of a tension roll of a temper mill. Background technique [0002] When the tension roller of the continuous annealing and tempering machine slips, there will be relative sliding between the strip steel and the roller, which will seriously affect the quality of the strip steel surface, and will also cause the rolling force, tension and elongation of the temper mill The fluctuation will affect the stable operation of the tempering machine. [0003] At present, there is a serious hysteresis in judging the slipping phenomenon of the tension roller of the skin pass mill. There is no effective technical method and means to determine the position and time of the tension roller slipping, and it is difficult to judge the slipping position and time of the tension roller in time.
