Abstract (en)
[origin: WO8908811A1] This invention relates to a method of constructing and shaping a converter steel tapping port incorporating therein a refractory material and a molten metal outflow port of a vacuum degassing furnace, etc., or method of repairing the breakage of said ports, to an apparatus for the method and to an impeller used for the apparatus. A material transferred via a material feed pipe from the downstream side of an impeller driven for rotation is discharged and caused to impinge against the impeller rotating at a high speed so that the material can be radiated in a circumferential direction and a compact refractory layer or a repair layer can be formed. Furthermore, partial repair can be made by supplying eccentrically the radiation material from the material feed pipe, and shaping of the molten metal outflow port can be made by fitting a cutter to the impeller.
