FIELD: metallurgical engineering industry, in particular, devices intended for setting the roll clearance and maintaining it with a high precision in accordance with signals arriving from the thickness automatic control system, or from the mill control board. SUBSTANCE: system uses a step motor, skew gearing, slide block, bell-crank and a throttle hydraulic control valve. The system is furnished with a bracket. The bracket is rigidly fastened to the body of the press unit and linked with the slide block through two mutually perpendicular springs.
