电渣重熔工艺中渣金两相的流动、传热及凝固

The flow field,heat transfer and solidifying of slag and ingot in ESR system

本文利用计算流体力学方法对电渣重熔过程中的渣相和金属相流动、传热以及相变进行了耦合数值模拟计算.通过分析结果,得到了电渣重熔过程中的温度场分布、流场分布以及其中的凝固情况.并在此基础之上,通过改变熔速来查看其对电渣重熔结果的影响,发现金属熔速增大,会使金属熔池内的温度普遍提升,金属熔池液变得更深更宽.

This paper presents a numerical analysis on slag, steel fluid and ingot of ESR using computational fluid dynamics method. According to the results, we get the flow field, heat transfer and solidifying in ESR system. And on this basis, we change melting speeds to see the results of the impact of ESR. With the metal melting speed increases, the temperature of the metal molten pool is rised, and the metal pool became wider.
