METHOD OF CONTROLLING SLIDING GATE VALVES, PARTICULARLY ON CONTINUOUS CASTING INSTALLATIONS

摘要

METHOD OF CONTROLLING SLIDING GATE VALVES, PARTICULARLY ON CONTINUOUS CASTING INSTALLATIONS During edge reversal (23) of the sliding plate (5) of a sliding gate valve (3) regulating the desired filling level (14) in a mould (9) from a throttled position (D1 or D2) into an opposite throttled position on the flow passage (7) at least the throttled position (D1 or D2) which is to be adopted-after an edge reversal 123) is specified by an operating sequence control preprogrammed in the processor (20) of the filling level regulation in order to counteract larger variations of the liquid level in the mould.
