| 摘要 |
The present invention relates to production of free cutting steels, more particularly a method for producing steels containing low melting point metals, such as free cutting steels. The method comprises the steps of: maintaining the low melting point metal in a molten state in a vessel (3), and allowing a controlled amount of the molten metal to flow down through a hollowed stopper rod (4) of a molten steel vessel (1) into the molten steel contained in the molten steel vessel (1). The method prevents leakage and provides a uniform mixture of molten steel. |
