| 摘 要： | 采用FLUENT大型商业软件和水模拟装置对某厂50tLF炉底吹氩喷嘴的布置方式进行了数值模拟和水模拟研究.分别讨论了单孔、双孔中心对称和双孔轴对称三种底吹氩喷嘴布置方式对钢液混匀时间的影响和钢液表面的卷渣情况.结果表明,在相同的吹氩量下,采用双孔轴对称底吹氩钢液混匀时间最短,在整个钢包内部及表面,钢液流动速度均匀而稳定,基本消除了搅拌死区,可以有效防止钢液卷渣,并为夹杂物的去除提供良好的动力学条件.

| Abstract: | Numerical simulation and physical simulation on the arrangement of 50 t LF with a bottom argon blowing nozzle were made by the commercial software FLUENT and a water simulation instrument. The effects of three different bottom argon blowing nozzle arrangement ways (haplopore,binocular central symmetry,and binocular rotational symmetry) on molten steel blending time and entrapped slag were studied. The results show that,with the same amount of argon,bottom blowing argon with binocular rotational symmetry get... |
