摘要
为了研究国内某钢厂100t双孔底吹氩钢包的流场现状,针对此钢包精炼过程流量200L/min(方案1)和300L/min(方案2)的钢水流动行为进行了数值模拟与现场实践。结果表明,每个吹氩流股均会在钢包形成两个循环流,分别位于流股与钢包壁之间和两个流股之间;方案2比方案1混匀时间缩短36s,渣眼平均直径增大0.055m,耐火材料侵蚀加重。数值模拟通过现场实践验证了其正确性,为现场生产提供了有效指导。
In order to investigate the current situation of its flow field,the numerical simulation and practice study of the flow behavior of molten steel in a 100 tladle with a double plugs bottom-blown argon refining process,which the total flow rate was 200(scheme 1)and 300 L/min(scheme 2)were carried out.The results showed that each argon blowing stream would form two circulating streams in the ladle,which were located between the argon streams and the ladle wall,and in the two argon streams.Scheme 2 shortens the mixing time by 36 scompared to Scheme 1 and the average diameter of the slag eyes increases by 0.055 m.The refractory material corrosion of Scheme 2 increased.The numerical simulation was verified its correctness by practice and the effective guidance for on-site production was provided.
