- causes of campers due to rolling of a sheet include poor roll gap setting, a difference in left and right sheet thickness of the material to be rolled, a difference in deformation resistance, and the like.
- a left-right difference is caused in the elongation strain in the rolling direction caused by rolling, so that a left-right difference is caused in the delivery side speed of the rolled material, thereby causing a jumper.
- the rolled material is sandwiched by pinch rolls on the exit side of the rolling mill, and the pinch opening has a uniform roll peripheral speed in the width direction at all times. If there is a difference between the left and right rolled material exit speeds that directly causes the camper, there is an inconsistency in the strip width direction between the peripheral speed of the pinch roll and the rolled material exit speed. As a result, a left-right difference occurs in the rolling direction (horizontal direction) force acting between the pinch roll and the rolled material. In other words, the side with the lower speed of the rolled material is relatively drawn in by the pinch roll, while the side with the higher speed receives the force in the direction of being relatively pushed back by the pinch roll.
- Such a lateral imbalance in the rolling direction force is manifested as a left / right difference in the reaction force in the rolling direction acting on the pinch mouth and a left / right difference in the rolling direction force acting on the working edge of the rolling mill through the rolled material. Change. By detecting and measuring any of these, it is possible to immediately detect the difference between the left and right of the elongation strain difference and the difference between the left and right of the rolled material exit speed that directly cause the camper at the time of occurrence.

- a left-right difference in elongation strain that causes campers a right-left difference in the tension of the material to be rolled between the winding device and the rolling mill will occur. Therefore, this will be manifested as a left-right imbalance of the rolling direction force acting on the work roll of the rolling mill.
- the left and right imbalance of the rolling direction force is calculated by extracting the component in the rolling direction from the measured value of the divided reinforcing roll load of the rolling mill, the calculated value can be used as a factor for the rolled material to be rolled. Directly reflects the left-right difference in the outboard speed Therefore, it is possible to prevent a jumper by controlling the left-right asymmetric component of the opening degree of the rolling mill based on this.

Rather, it has a so-called cluster-one structure in which the outlet side reinforcing roller group and the inlet side reinforcing roll group that are in contact with the work rolls are inclined with respect to the vertical direction and are separately arranged.
