SLIDE VALVE OBTURATOR FOR CONTROLLING MOLTEN METAL FLOW

摘要

The invention relates to a sliding gate valve for controlling the flow of molten metal from a vessel. The valve comprises an orificed fixed plate and an orificed sliding plate slidingly mounted on a hinged support sub-assembly. The sliding plate is biased into face to face contact with the fixed plate. The biasing means applies the biasing force directly on to the contact plane defined by the meeting faces of the two plates.
