Abstract
1330480 Spray refining and casting steel VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE A G 21 Dec 1970 [24 Dec 1969] 60614/70 Heading C7D Steel is continuously produced by spray refining liquid pig iron with a gaseous refining agent during addition of slag forming substances such as lime, fluospar and bauxite and, if desired coolants such as ore, limestone and scrap, pouring the steel and slag into a collecting vessel, the steel then being further treated in an electric furnace and then being continuously cast into bars. The steel may be vacuum treated before casting. The furnaces may be resistance arc furnaces or induction furnaces. Al, Si and/or C may be added to the slag in the collecting vessel, which may be kept fluid by heating and by addition of fluxes.
