LADLE MOLTEN METAL FEED SYSTEM AND LADLE MOLTEN METAL FEED METHOD

摘要

To provide a ladle molten metal feed system and a ladle molten metal feed method, in a ladle molten metal feed system provided with a ladle molten metal feed device in which the locus of the carrying operation of a ladle is fixed, where, upon molten metal injection into an injection sleeve by the ladle, by downwardly operating the ladle toward the bottom part of the injection sleeve, the relaxation of the entrainment of air caused by the turbulence of the molten metal, the prevention of the rebounding of the molten metal caused by the falling of the molten metal, the suppression of the scattering of the molten metal to the circumference caused by the falling of the molten, and the reduction of the damage of the injection sleeve caused by the falling of the molten metal from the upper part can be realized.SOLUTION: Provided is a ladle molten metal feed system provided with a ladle molten metal feed device in which the locus of the carrying operation of a ladle is fixed, in which, by providing a movement device moving the whole of the ladle molten metal feed device, upon molten metal injection into an injection sleeve, the ladle is downwardly operated toward the bottom part of the injection sleeve. Also provided is a ladle molten metal feed method by the ladle molten metal feed system.SELECTED DRAWING: Figure 3
