结合前期水模拟结果，利用FLUENT软件对100 t LF炉进行了底吹氩气的多相流数值模拟，模拟结果表明：优化后钢包熔池速度与湍流动能分别增大了12.2%和15.1%，死区体积减小了35.6%，有利于钢包内熔池的传热、传质以及夹杂物去除等。将优化后钢包底吹位置应用于某100 t LF炉，结果表明：T[O]去除率提高了6.3%，增[N]率降低了11.5%；大型夹杂物去除率提高5.7%；总夹杂物去除率提高了5.2%。达到优化钢包结构，改善钢液流动状态，促进夹杂物上浮，提高LF炉精炼的目的。

Combined results of water simulation, three-dimensional mathematical model for a 100 t ladle funace was developed in present work. The simulation results show that average velocity and turbulent kinetic energy of flow field increase by 12.2 % and 15.1%, with the dead zone decrease by 35.6%,which is good at heat transfer, mass transfer and inclusion removal. To test the simulation results, the bottom blowing layout applied to a 100 t ladle funace. The results show that the total oxygen removal rate is improved by 6.3%, and the nitrogen content was reduced by 11.5%; The rate of micro-sized inclusions removal is improved by 5.7%, and the rate of large-sized inclusion removal improved by 5.2%. Achived the purpose of flow field optimization of 100 t ladle funace.
