Abstract
PURPOSE:To prevent the generation of braekout and surface flaws by assuring a molten flux layer of sufficient thickness on the surface of molten steel. CONSTITUTION:A bottom is constituted in a water cooled copper mold 3 by means of a dummy bar 4 inserted therein from below, thence molten steel 8 is charged therein from a ladle 1 via a tundish 2, then part of molten steel 8 solidifies to form a bottom solidified shell 8'. While the molten steel 8 is held filled in the mold 3, a powder and granular mold flux 9 is charged and is partly after which a dummy bar 4 is begun to be drawn downward at a very low speed. In order to conduct the molten steel 9 into the mold 3 by assuring the flux layer 9 without exposing the molten steel 8 to the atmosphere, man-made graphite electrodes 7, 7' are inserted into the molten flux 9 on both sides of an immersion nozzle 10, and are so controlled with electrode elevators 6a that the leading ends of the electrodes are held in the layer 9 at all times. If electricity is conducted with such arrangement, the flux is melted successively, and is flowed in through the mold - casting meniscus, whereby the good lubricating performance is maintained.
