DEVICE FOR CONTROLLING PROFILED BILLET ROLLING IN THE ROLLING STAND OF A PLATE MILL WITH A HYDRAULIC PRESSURE DEVICE Russian patent published in 2022 - IPC B21B37/24 B21B37/62 

FIELD: rolling production.

SUBSTANCE: invention relates to the field of rolling production and can be used in automatic control systems for rolling a sheet from a slab billet at thick plate rolling mills. The device automatically switches the parameter controlled by the channel of hydraulic pressure devices (HPD), depending on the rolling mode, in one of which the rolling of the front end, the middle section and the rear end of the rolled sheet is carried out with specified constant reductions in the automatic thickness control mode. In another mode, the rolling of the profiled sections of the rolled sheet is carried out with variable compression in the mode of automatic control of the HPD position. To do this, the device is equipped, among other things, with three controlled keys, a thickness controller, a HPD displacement intensity setting device, a logic unit, a gauge for the output thickness of the rolled billet, a HPD position setting unit, and a block for setting the parameters of profiled billet rolling.

EFFECT: use of the invention improves the reliability of the device and the quality of rolled products.
