真空感应炉近常压气氛保护熔炼高氮马氏体不锈钢

Smelting of high nitrogen martensitic stainless steels by vacuum induction furnace under near normal protective atmosphere

研究了在真空感应炉近常压气氛保护熔炼条件下氮在马氏体不锈钢0Cr16Ni5Mo中的溶解度,探讨了炉内保护气体种类、氮化铬铁加入量对钢中氮含量的影响.结果表明,炉内保护气体种类对钢中氮的溶解度有较大影响,氮化铬铁合金加入量对钢氮含量的影响因保护气体种类不同而异.

The solubility of nitrogen in martensitic stainless steel 0Cr16Ni5Mo when smelted by vacuum induction furnace under near normal protective atmosphere was investigated.The effects of the protective gas type and the nitrided ferrochromium addition level on nitrogen content in the high nitrogen martensitic stainless steel were discussed.The results show that the protective gas type has a significant effect on the nitrogen content in steels and that the effect of nitrided ferrochrome addition level on nitrogen content varies with the types of the protective gas.
