本文纵谈了国内主要不锈钢生产厂家应用炉外精炼工艺冶炼不锈钢的情况,重点总结了VOD的发展概况、工艺特点及精炼工艺,通过冶金效果分析进一步总结了影响不锈钢脱碳与铬回收率的因素。提出了本钢特钢公司应在借鉴兄弟厂经验的基础上,充分发挥VOD的真空脱气作用,大力发展不锈钢精炼工艺。进一步降低生产成本,占领国内市场。 In this paper, the situation of smelting stainless steel by furnace refining process of major domestic stainless steel manufacturers is briefly discussed. The development overview, process characteristics and refining process of VOD are summarized. The factors influencing the decarburization and chromium recovery of stainless steel are further summarized through metallurgical analysis. Proposed Benxi Steel Company should learn from the experience of Brothers plant, give full play to VOD vacuum degassing, vigorously develop the stainless steel refining process. To further reduce production costs, occupy the domestic market.
