【摘要】 在25Kg真空感应炉上用镁钙合金对超低碳奥氏体不锈钢00Cr18Ni10进行了保碳脱氧研究。通过控制充入纯氩所达到的炉内压力和精炼时的反应温度,以及调整镁钙合金和助熔剂CaF₂的比例和数量,可以使得精炼后00Cr18Ni10的O含量降到了4～6ppm,同时Mg、Ca残余量在痕量范围内,而增碳甚微。更多还原

【Abstract】 Some problems of deoxidization of the ultra-low carbon austenitic stainless steel 00Cr18Ni10 were studied using Ca-Mg alloy in a 25 kg vacuum induction furnace. Controlling the pressure of argon that was boosted in the furnace and the reaction temperature in refining process and adjusting the quantity and proportion fo Ca-Mg alloy and CaF2 that is used as fluxing agent, the total content of O2 can be reduced to (4-6)×10,and the residual contents of Mg and Ca in the steel are very small. But, the content of carbon changes slightly.更多还原
