FIELD: rolled stock production, namely hydraulic systems for keeping constant distance between rolls of rolling mill, for example rolling mill with prestressed stands and with automatic control of inter-roll gap.
SUBSTANCE: hydraulic apparatus includes hydraulic cylinders mutually connected through pipelines and arranged between chocks of rolling rolls; control hydraulic device; pump; safety valve and accumulator for providing low pressure. Hydraulic device includes three hydraulic distributors connected with pump. One distributor is connected accumulator; second distributor is connected with hydraulic cylinders and third distributor is connected with safety valve.
EFFECT: enhanced operational reliability of apparatus, improved accuracy of inter-roll gap regulation.
