摘要
以某钢厂30 t钢包为原型,通过模拟试验研究,在相似原理的基础上,建立水模型进行了冷态模拟,利用数值模拟软件观察了不同工况下(吹气位置,吹气量)钢包的流动特征,优化设计了钢包底吹氩吹气位置、吹气流量和精炼渣厚度。确定了钢包快速混匀和夹杂物最短上浮时间时吹气流量以及吹气位置,明确了影响钢包吹氩精炼效果的因素,指导实际生产。
This experiment takes a 30-ton steel ladle from a certain steel plant as the prototype.Through simulation experiments,based on the principle of similarity,a water model has been established for cold state simulation.Numerical simulation software has been adopted to observe the flow characteristics of the ladle under different working conditions(blowing position,blowing volume),and the design for argon blowing position,blowing flow rate and refining slag thickness of the ladle have been optimized.The blowing flow and blowing position for rapid mixing of ladle and minimum floating time of inclusions have been determined,and the factors that affect the effect of argon blowing refining of the ladle have been clearly defined,which can be used as the guidance for the actual production.
