Abstract
PURPOSE:To produce the captioned steel having the surface layer rich with alloy components by dividing the molten steel jet flow being poured into the continuous casting mold to the upward direction and downward direction and adding alloy within the flow range of the upward flow. CONSTITUTION:The molten steel poured from a tundish is supplied through an immersion nozzle 2 into a mold 1. In the mold 1, the molten steel 4 surface is perfectly covered with molding powder 8 and is therefore not oxidized. The alloy material 7 to be added is added as wire- or plate-form from pintch rolls 6 into the molten steel 4 through guide 5 and floating guide 9. The molten steel jet flow from the nozzle 2 is divided to the upward molten steel (a) and downward molten steel (b) and the alloy material 7 is perfectly melted by the upward molten steel flow (a). Because of this the molten steel upper part in the mold 1 becomes the molten steel rich with the added alloy material and the molten steel is divided to two layers, thus the clad steel is produced.
