摘　　要：为研究复合铸钢支承辊在差温加热后的油淬冷却过程中的温度场变化情况,采用交替隐式有限差分方法,建立了包含变物性的淬火温度场计算模型,应用Visual Basic软件计算了φ1 550 mm×1 700 mm的工作层为40CrNiMoA、辊芯材质为35钢的复合铸钢支承辊的油淬冷却过程的温度场,并把计算结果与实测结果进行了比较,发现两者基本符合。In order to investigate the temperature field of composite casting bearing roller during oil quenching process after differential heating, the alternative direction implicit finite difference model which comprised variable physical property parameters was established. Visual Basic software was used to calculate temperature field in oil quenching process of composite casting bearing roller, with size of Ф1550mm×1700mm, in which 40CrNiMoA and 35 steel were used as work layer and rollercore, respectively. The simulation results and the tested results were compared.
