CONTROL SYSTEM OF DOUBLE COAXIAL FLOATING UNCOILER Russian patent published in 2010 - IPC B21C51/00 B21C47/00 

FIELD: metallurgy.

SUBSTANCE: system includes drives of axial movements, which are connected to uncoiler drums. At that, system is equipped with control hydraulic system made in the form of two hydraulic motors of uncoiler drums, two hydraulic cylinders of axial positions of uncoiler. Cylinder stocks are connected to linear displacement transducers; piston cavity of one of the cylinders is connected to pressure sensor and each cylinder is equipped with a distributor with proportional control. Hydraulic motor inputs of uncoiler drums are connected to pressure switch; supply line connecting the inputs of their control distributors to each other is equipped with pressure switch, safety valve, and is connected by means of distributors to working pressure main line of hydraulic system, high pressure source and reduced pressure source.

EFFECT: enlarging process capabilities of equipment, improving the quality of rolls and increasing capacity owing to reducing the time required for installation of a roll.
