摘　　要：通过对带钢热连轧过程传热关系的分析,利用有限差分法建立了带钢三维温度场的数值计算模型。结合攀枝花钢铁集团公司热轧生产线的实际条件,利用该模型模拟了精轧区带钢的温度场,并与实测结果进行了比较,验证了模型的可靠性。在此基础上,讨论了终轧厚度和轧制速度对带钢温度场的影响,为改进和优化轧制工艺提供了理论依据。Based on the analysis of heat transfer in hot strip rolling process, a mathematical model for numerically simulating the threedimension temperature distribution in the strip during multipass rolling process is developed. By using the developed model, the temperature field of the strip in a real production is simulated, and the reliability of the simulating results is verified by comparing with the measured strip temperatures. Moreover, the effect of process parameters on the temperature distribution in the strip is discussed.
