摘　　要：本文基于ANSYS有限元软件建立了热轧钢板超快冷过程热力耦合数值分析二维模型,对超快冷过程钢板厚度方向温度和热应力的分布进行了数值模拟,分析了超快冷条件下初始温度、板厚、碳含量及表面换热系数对钢板温度和热应力的影响。A two dimensional model of thermo-mechanical coupling simulation on ultra fast cooling （UFC） for hot rolled steel plate was established and the distribution of temperature and thermal stress in thickness direction was analyzed by ANSYS FEM software. The effect of initial temperature, thickness, carbon content and surface heat transfer coefficient on sheet temperature and thermal stress were analyzed.
