摘　　要：采用ANSYS有限元软件,以方坯连铸结晶器为研究对象,基于节点温度传递方法、利用ANSYS接触分析技术建立方坯连铸结晶器三维瞬态传热有限元模型,分析了结晶器内铸坯和结晶器铜壁的三维温度场及结晶器内铸坯坯壳分布规律。结果表明,弯月面区域铜壁温度较低,上口接近水缝内冷却水温度;弯月面下50 mm处结晶器铜壁温度最高,达到157℃;模型计算所得结晶器铜管高温区域形状与实际生产中下线铜管高温过烧区域形状基本一致;铸坯表面偏离角部30 mm处角部影响消失,铸坯表面温度趋于一致。Using the finite element software ANSYS, the squire billet continuous casting mold as the research object, based on the node temperature transfer method, using the ANSYS contact analysis technology to establish billet continuous casting crystallizer three-dimensional finite element model of the transient heat transfer, the distribution of the blank shell and the mould was analyzed. The results show that the copper wall temperature in the curved surface area is lower, and the upper mouth is close to the temperature of cooling water in the water seam. Meniscus under 50 mm copper mould wall temperatures is the highest, up to 157 ℃; the shape of the copper tube is basically the same as that of the copper tube in the actual production. The surface of casting billet is removed from the angular part 30 mm, and the surface temperature of the slab is uniform.
