摘　　要：小H型钢成品的组织性能与轧制过程的温度紧密相关,特别是终轧的温度。结合现场测量结果,应用有限元分析软件对轧制过程的温度场进行模拟,并通过对Q235小H型钢轧制过程各轧制阶段温度的实际测量,与有限元分析结果进行比较,两者误差较小,验证了有限元分析结果的正确性,得到了各阶段H型钢断面温度分布特点以及内外温差值。分析结果对制定加热温度、轧制过程冷却参数、轧制工艺参数和进行轧后控冷等提供了有效参考。The mechanical properties of small H-beam is dependent on the temperature of hot rolling process, especially the temperature of final hot rolling. Numerical simulation of the temperature field of hot rolling process was made by means of the soft-ware of Finite element analysis based on the measured temperature result. The error of actual measuring temperature of several rolling stages and the results of finite element analysis is very small. The temperature values of several rolling stages and difference of inner and outer of H-beam were gained. The analysis result is important for establishing the heating temperature and cooling parameter and hot rolling process parameter.
