Molten material treatment apparatus

A molten material treatment apparatus comprising:

• a container having an upper portion, on which a molten material injection part is disposed, and a bottom part in which a hole is formed;
• a gas injection part attached to the bottom part between the molten material injection part and the hole;
• a chamber part formed on the upper portion of the container so as to face the gas injection part and having an inside open downward;
• and
• a plurality of vertical members disposed so as to cross a plurality of positions of a rotary flow region formed between the chamber part and the bottom part,
• wherein the gas injection part is provided in plurality and the plurality of gas injection parts are spaced apart from each other, and the respective gas injection parts are spaced apart from each other with at least two vertical members among the plurality of vertical members interposed therebetween,
• wherein the respective vertical members are disposed respectively crossing three or more positions of the respective rotary flow region, and at least any one of the plurality of gas injection parts is positioned so as to face any one vertical member among the plurality of vertical members.
