Abstract

PURPOSE: To prevent the generation of arc between the leading end of an electrode and the surface of a molten metal and to conserve remelting electric power by a method wherein a metal consumable electrode is divided into plural parts and a redetermined amount of high resistivity slag is used.
CONSTITUTION: In refining and casting a metal by remelting, a plurally divided metal consumable electrode is put in a mold 4 and a high resistivity slag is added in an amount smaller than the amount defined by formulaI. In this case, slag thickness parameter defined by (slag wt.)/(mold cross area) is adjusted to a range shown by formula II. By this method, even if an amount of slag 2B is small, are is not generated between the leading end 11 of the electrode and the surface of a molten metal 3 as well as heat release surface is made small and electric power is conserved.
