METHOD OF TREATING SURFACE OF METALLIC CONTINUOUSLY CAST BILLET Russian patent published in 1996 - IPC

FIELD: electric metallurgy, namely, treating of surface of metallic billets by electric slag process. SUBSTANCE: method comprises steps of arranging billet with inclination relative to horizon and performing electric slag process simultaneously in successively arranged according to remelting process mutually insulated slag melts; performing in first melt heating up of surface with use of non-consumable electrode and in second melt - fusion of defect layer of billet and formation of melt metal with use of consumable electrodes. Temperature of heating up surface of billet by first slag melt consists 0.5-0.99 of solidus temperature of metal of billet. EFFECT: enhanced quality of surface of continuously cast billets. 3 cl, 2 dwg
