ABSTRACT:
A sliding closure unit includes a movable plate movable between open and closed positions to control the discharge of molten metal through an outlet opening of a metallurgical vessel. When the movable plate is in the closed position, a continuous flow of gas is injected from a gas supply system through the area of the movable plate confronting the outlet opening into the outlet opening. When a predetermined gas back pressure occurs in the gas supply system, indicative of solidification of molten metal in the outlet opening, at least one pressurized gas jet at a pressure of at least 12 bar is injected from a compressed gas supply system into the outlet opening, thereby clearing away any solidified metal from the outlet opening. This makes it possible to ensure that, when the movable plate is moved to the open position, the molten metal will be discharged through the outlet opening at a full flow rate of discharge.
