Steel ladle accident rotation control valve stack

Abstract

The invention relates to a steel ladle accident rotation control valve stack and belongs to the technical field of continuous casting equipment in the metallurgical industry. The technical scheme is as follows: a left pile of hydraulic valves and a right pile of hydraulic valves are arranged on the front surface of a manifold block (1); a manual motor reversing valve (2) is arranged at the uppermost of the left pile, a superposed one-way throttle valve (4) is arranged in the middle, and an overflow valve (5) is arranged on the lower part; a manual clutch reversing valve (6) is arranged on theupper part of the right pile, and a pressure reducing valve (8) is arranged on the lower part; a pressure oil pipe joint (3), an oil return pipe joint (11) and a leakage oil pipe joint (12) are arranged below the manifold block (1); and a lower flange (13), an upper flange (14) and a clutch control oil pipe joint (15) are arranged on the back of the manifold block (1). The steel ladle accident rotary control valve stack has the beneficial effects that ladle turret can be rotated in an accident state, and major production accidents are avoided. The phenomenon that the ladle turret cannot be driven due to the fact that the hydraulic valves cannot work flexibly is avoided when the ladle turret is electrically powered off or burnt down in the accident state.

Description

technical field [0001] The invention relates to a ladle accident rotation control valve group, which belongs to the technical field of continuous casting equipment in the metallurgical industry. Background technique [0002] The ladle turret is an important equipment in the continuous casting machine. Its function is to receive the ladle filled with molten steel from the steelmaking bridge, transfer the ladle to the pouring position of the continuous casting bridge for pouring, and rotate the empty ladle back to the smelter after pouring. Steel span. Among them, the ladle turret is driven by the reducer, and the side connected to the two input shafts of the reducer is a motor. When the ladle turret is working normally, it is driven by the motor to drive the reducer, which is normal driving. The input end on the other side of the reducer is connected to the hydraulic motor. When the main power supply or electrical equipment of the whole plant fails, the hydraulic motor is dr...

AI Technical Summary

Problems solved by technology

The current ladle accident rotation device has the following problems: the control of the hydraulic clutch in the ladle accident rotation control valve group adopts electrical control or hydraulic control. When the ladle turret is in an accident state, the electrical system is often burned, and electrical control cannot be used; Or because the hydraulic valve has not been used for a long time, the spool is jammed, and the hydraulic clutch cannot be operated to realize accidental drive, so that the accidental rotation of the ladle cannot achieve the intended purpose
