摘　　要：为研究某厂的钢包烘烤效果,对烘烤过程的流动、燃烧、传热现象进行数值模拟研究,利用计算流体力学软件FLUENT,采用有限差分方法和速度-压力耦合算法SIMPLE,重点分析了不同煤气流量和煤气成分下,钢包内温度分布的变化规律,并进行了实验验证。计算结果与实验及工程现象基本吻合,证明该模型对指导现场生产具有重要意义,为该厂钢包烘烤过程中混合煤气的使用提供了重要依据。In order to study the effect of the baking temperature of ladle,numerical simulation of gas flow,combustion and heat transfer in ladle during the baking process were carried out. Using fluent code with finite difference and SIMPLE methods,the temperature distribution of ladle baked at different flux and composition of gas were studied numerically and experimentally. The simulation results were basically consistent with the measured,providing important basis for the use of mixed gas during ladle baking. This model can be used to guide the production.
