摘要： A method is provided for producing large steel ingots with increased yields by casting a steel ingot to the desired final size, removing metal to form an axial central cavity, melting a steel electrode under a fused slag in the axial cavity while simultaneously remelting and refining a proportionate controlled portion of the ingot wall surrounding the central cavity by action of the fused slag and solidifying the combined melted electrode and melted metal from the ingot wall integral with the remaining ingot shell to form a composite solid ingot mass.

摘要： A method is provided for preventing shrinkage cavities and voids in steel ingots by the steps of forming a body of degassed molten steel in an ingot mold and continuously supplying molten steel by vacuum arc remelting an electrode into the body of molten steel at a controlled rate substantially equal to the volume loss by shrinkage on cooling until the body of steel is solidified.

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.
摘要翻译： 提供了一种通过将没有槽头的钢锭铸造在主体上的方法来生产大型钢锭，沿长度方向移除锭的轴向芯以形成中心腔，通过使电气通过电熔融熔化炉渣内的钢电极 电流通过电极并使空腔中的熔体固化。 控制来自腔壁和电极的金属的相对比例以提供所需的锭组成和结构。

摘要： A method is provided for producing large ingots by the steps of casting an ingot, forming an axial hole through the ingot and progressively melting and refining the central zone of the ingot at the axial hole by electroslag remelting technique and progressively resolidifying the metal in the hole to form a solid ingot.
