摘要
针对不锈钢冶炼特点,通过脱碳热力学和动力学分析,研究了VOD精炼工艺参数对超纯铁素体不锈钢脱碳速度和终点碳含量的影响,并进行了大量工业生产试验。结果表明,提高冶炼温度、增加吹氧流量和吹氩流量、降低氧枪的供氧压力和枪位有利于提高脱碳速度,获得更低的终点碳含量。
Based on the feature of stainless steel melting the effect of VOD process parameters on the decarbonization rate and end carbon is investigated by dynamics and thermodynamics analysis of decarbonization and a lot of industrial tests are carried out. The results indicate that higher decarbonization rate and lower end carbon content can be achieved by raising the melting temperature, increasing O2 flow rate and Ar blowing rate, reducing oxygen pressure and oxygen lance position.
