Abstract: In an electric arc furnace system for making steel, a method and structure (1) for eliminating teeming hang-ups and ensuring temperature homogeneity in a ladle which teems into an ingot mold by gas purging at all possible steps under both atmospheric and vacuum conditions, and (2) for preventing non-metallic inclusions from appearing in the final product by deflecting the granular material in the teeming ladle well block away from the ingot mold by a heat resistant but combustible deflector just prior to entry of the teeming stream into the ingot mold.

Abstract: A combined arc furnace, ladle metallurgical furnace and vacuum degassing system having the flexibility to produce at least non-vacuum arc remelt, vacuum arc remelt, vacuum oxygen decarburized non-vacuum arc remelt, and vacuum oxygen decarburized vacuum arc remelt steels from one off to continuous casting end uses in steady state or randomized order which utilizes only a minimum of energy attributable to preheating hot metal contacting components of the system followed by heat loss reduction of the components and use of a carryover heel in the arc furnace, in which the throughput of the system is limited solely by the melting capacity of the arc furnace.
