In the process of steel rolling, roll wear will cause the bad shape of the strip. The hot mill adjusts the shape of the plate by moving the roll and bending the roll. Among them, the control method of the bending roll to the shape of the steel plate is limited by the rigidity of the equipment, and the control ability cannot be changed.

In the process of steel rolling, roll wear will cause the bad shape of the strip. The hot mill adjusts the shape of the plate by moving the roll and bending the roll. Among them, the control method of the bending roll to the shape of the steel plate is limited by the rigidity of the equipment, and the control ability cannot be changed. The adjustable space of the controllable channeling roll is huge, and different degrees of channeling roll can be realized by designing the shape of the roll surface, and then the shape of the plate can be adjusted.

In order to improve the bad shape of hot strip steel products, the regulation law of plate shape of the unit was studied.
