摘　　要：结晶器是连铸的核心部件,其传热状态及力学行为直接影响到铸坯的质量以及结晶器的寿命。基于有限元方法,建立了全尺寸结晶器模型,模型考虑了宽面铜板、窄面铜板、弧形水槽、镍镀层等结构,基于热电偶获得的实测数据,利用反问题算法求解热流,将数值模拟与实际数据相结合。通过此模型,全面分析了结晶器的温度、应力及变形情况,为连铸过程优化及结晶器设计提供理论依据及指导。Mold is the key component of continuous casting. The thermal and mechanical behaviors of mold would affect the slab quality and mold life. Based on finite element method,a full scale finite-element model of mold was built,including four copper plates,nickel layer and water slots with different depths. An inverse algorithm was applied to calculate the heat flux through the measured temperatures by thermocouples buried inside the mold plates,so the numerical model was combined with the measured data. Based on the model,the temperature,stress and distortion were analyzed,and it will be helpful for the process optimization and structure design for the slab continuous casting mold.
