    摘要: A method is provided for producing large steel ingots by casting a steel ingot free from sinkhead on the body, removing an axial core lengthwise of the ingot to form a central cavity, melting a steel electrode within the cavity under a fused slag by passing an electrical current through the electrode and solidifying the melt in the cavity. The relative proportions of metal from the cavity wall and the electrode are controlled to provide the desired ingot composition and structure.
