Abstract

847,831. Casting-processes. BOCHUMER VEREIN FUR GUSSSTAHLFABRIKATION A.G. Feb. 19, 1957 [Feb. 22, 1956], No. 5631/57. Class 83 (1). Steel ingots of 25 tons or more weight are poured into moulds having a length-to-internaldiameter of less than 1.6 and situated in a vacuum-chamber, the melt being then covered with a deoxidizing slag, and the top of the ingot electrically heated, e.g. by an electric arc, so that the ingot solidifies gradually from the bottom to the top.
