Abstract

PURPOSE:To form an even alloy layer on slab surface layer part with good volume productivity and workability by feeding the alloy wire which is supplied with current with a power feed shoe between a partition wall which is partly dipped below molten steel level and has an electrode and the inside wall of a continuous casting mold and arc melting the alloy to liquid drops. CONSTITUTION:Molten steel 4 is injected into a continuus casting mold 1 from a tundish 2 through an immersion nozzle 3. An alloy wire or tape of Ni or Cr is sent from a wire drum 11 onto the molten steel 4 surface of the mold 1 through driving of pinch rolls 12. A partition wall 7 serving also as an electrode 6 is provided by being partly dipped near the inside wall of the mold 1. On the other hand, high voltage current is flowed via AC-DC converter 14 from a power source 15 to the wire 8 through a power feed shoe 9 to cause the arc melting of the wire between the partition wall 7 and the inside wall of the mold 1. Inert gas is blown into a guide pipe 10 to add and diffuse the alloy having been molted to liquid drops into the molten steel 4. The liquid drop alloy forms a solute stagnating area under the molten steel surface and this is cooled and solidified to become an alloy layer.
