Abstract
PURPOSE: To suppress waving of a molten pool and prevent the defective shape of the surface by keeping the charging eletric power of plasma torches in the rear stage in a slag melting direction at a valve below the predetermined value in melting and mending the slag surface by means of the plasma torches.
CONSTITUTION: Plasma torches 3-1 and 3-2 provided in parallel upward in the advancing direction of a slab 1 are caused to generate plasma arcs 5-1 and 5-2 by a driving coil 4, whereby the surface of the slab 1 is melted and a molten pool 11 is formed. At this time, the charging electric power for the plasma torch 3-2 in the rear stage of the melting direction of the molten pool 11 is kept at a predtermined value or below. Then, the waving of the molten pool 11 below the plasma torch 3-1 of the front stage is made smooth, and the molten pool solidifies.
