摘　　要：通过建立液态钢渣粒化和凝固过程的物理和数学模型,利用FLUENT软件对不同条件下的粒化和凝固过程进行数值模拟。结果表明:氮气射流的冲击动能以及射流的流场分布规律对液态钢渣的粒化效果影响显著;0.5 MPa氮气压力下,温度场分布规律和粒化效果均好于0.3 MPa的;1 m/s风速下渣粒的凝固时间为1.45 s,340 m/s风速下渣粒凝固时间为0.25s,凝固时间缩短了1.2 s。The mathematical and physical models of granulation and solidification process for liquid slag were established by using the FLUENT software to calculate the processes. The simulation results showed that the strike kinetic energy and the flow field distribution of the N2 jet had a significantly influence on the effect of granulation. Under the 0. 5 MPa nitrogen pressure, the temperature field distribution and the effect of granulation was better than that of 0.3 MPa nitrogen pressure condition. The solidification time of l m/s flow velocity was 1.45 s, but the solidification time of 340 m/s was 0.25 s, the solidification time of the latter was shorter than that of the former about 1.2 s.
