钢水浇注时防止金属二次氧化的方法俄罗斯马格尼托哥尔斯克冶金工厂根据钢水在浇注时，单独使用氩气保护并不能充分防止它的二次氧化的情况进行了这一研究。研究发现，使用带槽的档盖，可以提供浇注保护。浇注时，将这种档盖与氩气保护联合使用，则可以有效地保护钢水免受... Method of preventing metal secondary oxidation during pouring of molten steel The Magnonot metallurgical plant in Russia carried out this study on the basis that the molten steel was cast using argon alone alone and did not sufficiently prevent its secondary oxidation. The study found that the use of grooved cover, can provide pouring protection. Pouring, the use of such a cover and argon protection combined, you can effectively protect the molten steel from ...
