Abstract

671,678. Ladles; refining metals ; steel. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. June 23, 1949 [June 29,1948; April 19, 1949], Nos. 16741/49 and 16742/49. Classes 72 and 82(i) In a method of introducing gas into a bath of molten steel and other metals by blowing it through porous refractory bodies which are in direct contact with the bath, the porous bodies are removably fitted within apertures in the refractory lining of the container for the molten metal. In a ladle b for introducing gas into a molten metal, the gas is fed through a tube d into a blast chamber e in which it flows around the block f and diffuses through it into the molten metal. The porous block, which is preferably set with its 'larger base in contact with the molten metal, has seven blind holes j to ensure regular distribution of the flushing gas and the side is made gas-tight by stove enamelling or by means of a compact refractory material. The refractory lining of the ladle may be anchored, e.g. by grooves or projections to the metallic casing b. The flushing gases may be inert gases, e.g. nitrogen, helium, argon or mixtures thereof, with the optional addition of active gases, e.g. oxygen, for removing undesirable gases, e.g. hydrogen from the bath and/or of enriching it with suitable gases, e.g. nitrogen, and are preferably preheated.
