Abstract
PURPOSE: To enable gas to be repeatedly blown into a refining container by clogging the tops of the through holes of a plurality of gas blowing bottom nozzles of the container with a filler; pouring molten metal into the container; blowing the gas from an arbitrary nozzle; and using other nozzles in order after discontinuing the blowing.
CONSTITUTION: Nozzles 6, 6 are attached to the bottom of ladle A, and filler B consisting of MgO clinker 8 and silica sand 9 is mounted on the tops of nozzles 6, 6. Molten metal roughly decarburized in an electric furnace is poured into ladle A, and Ar gas 5 or the like is blown from through hole 7 of one of nozzles 6, 6 in a vacuum tank, whereby filler B floats immediately. By reducing the gas press. to zero in the blowing, part of the molten metal flows into hole 7, yet it solidifies immediately to clog hole 7. After charging a compsn. -adjusting alloy or the like under atmospheric press., Ar gas 5 can be blown similarly from through hole 7 of other nozzle 6.
