Hydraulic control device for guide and guard of roughing mill

The utility model discloses a roughing mill guide hydraulic control device, which relates to the technical field of steel smelting equipment, and is characterized in that when the roughing mill guide hydraulic control device is suddenly powered off, a pilot valve is powered off and stops working, a hydraulic control one-way valve is in a closed state, and at the moment, a guide tends to fall due to downward gravity of the guide of a hydraulic cylinder; the hydraulic control one-way valve can drive oil liquid to be pressed back to the proportional pressure reducing valve from a rod cavity of the hydraulic cylinder, however, due to the fact that the hydraulic control one-way valve is in a closed state, the oil liquid is prevented from flowing back, the guide is locked and prevented from falling down, and the accident that a rolled plate blank collides with the guide due to the fact that the guide falls down when power is suddenly cut off is prevented. 本实用新型公开了一种粗轧机导卫液压控制装置，涉及钢铁冶炼设备技术领域，本申请的粗轧机导卫液压控制装置在突然断电时，先导阀
