| 摘 要： | 本文以工业试验和大量生产数据为基础,对VOD法冶炼不锈钢的工艺进行了分析,着重讨论了VOD过程钢水温度变化规律及工艺因素对它的影响,并指出,供氧制度(包括枪高,氧气流量和氧气压力),真空制度的合理配合是控制氧化期钢水温度的关键。还原期的温降受吹后的温度、还原处理时间及铁合金冷却剂、造渣剂的加入量等因素的综合影响。通过建立随机模型进行了定量的描述。针刘氧化期喷溅问题,给出了合理的供氧强度范围。对VOD过程元素变化及去碳保铬反应做了热力学分析讨论。

| Abstract: | Based upon the industrial test and production data, the VOD process formaking stainless steel is discussed in this paper.Temperature varition during VOD treatment was analysed.The result shows that the technical parameters influence the temperature greatly.It is important to control the temperature of oxidation period,which it depend on adjusting oxygen supply system (including lance height, oxygen supply rate and oxygen pressure) and vacuum system reasonably. The temperature dropping during reducing treatment was influe nced by the temperature after oxygen blowing,amount of additions, such as ferroalloy coolants and reduction mix,and redu-cing treatment time.A suitable range of oxygen supply rate was given to avoid splashing of steel.And also,analysing the element variation and dec-arburization reaction on the basis of thermodynamics. |
