摘　　要：应用电阻法对试样快速加热,然后对其进行高温锻压,并结合实验过程及参数,基于deform-3D软件对F40船板钢高温锻压过程的温度场及组织演变进行模拟。结果表明,试样的辐射系数为0.7,与空气的换热系数为0.02 k W/m2·K,模具与试样的传热系数为16 k W/m2·K。模拟结果与实验测得的温度场结果吻合度较好,验证了计算机模拟的可靠性和准确性。同时,结合温度场对试样组织演变进行模拟,并通过实测验证了模拟的正确性和可靠性,对实际生产具有参考意义。The sample was heated rapidly by means of resistance heating method,and then was forged in high temperature. Combining with the experiment process and parameters,Deform-3D software was used to simulate the temperature fields and microstructure evolution of the steel F40. The results showed that the radiation coefficient of the sample was 0. 7,the heat transfer coefficient of it in the air was 0. 02 k W / m2·K and the heat transfer coefficient between the sample and mold was 16 k W/m2·K. The simulation results of temperature fields agreed well with the experimental measured value,which proved the accuracy and validity of the simulation. Moreover,the microstructure evolution of steel F40 was also simulated combined with the simulation results of temperature fields,which was also proved accurately by experimental results, and offered an important reference meaning to real production.
