溶融金属処理剤および溶融金属処理方法

Molten metal processing agent and molton metal processing method

Abstract

PROBLEM TO BE SOLVED: To provide a molten metal processing agent and a molton metal processing method that can prevent oxidation and vaporization of molten metal and that exert no adverse effects on the environment. SOLUTION: In a pressure container 1, there is filled a molten metal processing agent composed of a liquid mixture in which 0.01-10 mass% phloro-ketone is dissolved in liquefied carbon dioxide. This molten metal processing agent is vaporized in an evaporator 2 and supplied to a melting furnace as an atmospheric gas that comes into contact with the surface of the molten metal.
