异型坯连铸结晶器铜板的温度场是控制钢坯质量的重要因素之一。本文针对某近终形异型坯连铸结晶器，考虑钢水和结晶器铜板之间的接触传热，以及铜板镀层和保护渣的热阻，给出了钢水和结晶器铜板之间的综合换热系数，进而采用ABAQUS有限元软件对结晶器铜板的温度场进行数值模拟。给出了不同铜板厚度、不同冷却水流速以及改进水槽和水孔设计等方案下铜板的温度场，为铜板的优化设计提供依据。

The temperature field on the hot surface of the blank continuous casting mould is a key factor controlling the quality of the billet. In this paper, the contact heat transfer between the molten steel and the mold, the thermal resistance of the coasting and the protecting slag and the comprehensive heat-transfer coefficient are discussed. The temperature field of a typical mold is then numerically simulated by means of the finite element software ABAQUS. The numerically determined temperature fields of the mold in different design schemes, including different mold thickness, different velocities of cooling water and improvement of the cooling water tank and hole, provide a reference for the optimization of the molds.
