Abstract (en)

[origin: WO9718050A1] The invention relates to a process for closing a tap hole (14) in the bottom (13) of a vessel (10) filled with a metal melt, with a tubular closure (31) in the furnace vessel movable vertically towards and away from the entrance of the tap hole (14) and a closing device (20) fitted beneath the vessel bottom, in the following steps: a) a compressible fireproof material is fitted at the aperture (16) of the closure (31) before each closing process, b) immediately before the immersion of the fireproof material in the melt, a medium is supplied in the closing direction in sufficient quantity largely to prevent its contact with the melt, c) during the closing process the aperture (16) of the closure (31) for blocking the tap hole (14) is guided through the melt and pressed against the vessel bottom (13) with sufficient force to compress the fireproof material, d) then the closing device (20) is taken in the known manner outside the vessel in front of the tap mouth and the tap hole is filled with a pourable fireproof compound via the tubular closure. The invention also relates to the device.
