发明名称 Method for preventing oxidation of melted metal
摘要 A method for preventing oxidation of melted metal at its surface. This method comprises the preparation of fine globules of a heat-resistant inorganic material divided into three groups differing in diameter from each other, said globules being coated with soft metal films so that they may come in closer contact with each other. The foregoing globules are deposited on the melted metal suitably so as to intercept the contact between the melted metal and the atmosphere.
