Patent DE-3934601-C1 (DE)
IPC: B22D41/14
Filed: 1989-10-17
Granted: 1990-10-04
Abstract: A closing and/or regulating apparatus for tapping molten metal from the interior of the metallurgical vessel includes an inner refractory pipe having extending through a wall thereof at least one opening and an outer refractory pipe fitted over the inner pipe and having extending through a wall thereof at least one opening. Outer and inner surfaces of the inner and outer pipes, respectively, define mating sealing surfaces. One of the pipes is fixedly mounted to a metallurgical vessel, and the other pipe is movable axially and/or rotatably relative to the one pipe to thereby selectively bring the openings to the two pipes relatively into and out of alignment. The inner pipe has adjacent an inner end thereof at a position inwardly of the opening therein a closure closing the interior of the inner pipe. The outer pipe defines therein a space forming a gas distribution chamber at a location confronting the closure. A gas, for example an inert gas, is introduced into the gas distribution chamber such that the gas passes therefrom between the sealing surfaces and into the openings.
