在高效连铸过程中,结晶器的传热效率起着至关重要的作用。根据小方坯结晶器的传热特点,应用三维非稳态有限元传热数学模型对结晶器在浇注过程中的温度进行模似,获得结晶器温度场分布及变化情况。同时对工艺参数中结晶器铜壁厚度和冷却水流速对结晶器温度的影响进行研究,经现场验证表明,合适的结晶器壁厚为10mm,合适的冷却水流速为10m/s左右。
In the efficient casting process, the heat transfer efficiency of the mold plays a crucial role. According to the heat transfer characteristics of the billet mold, the temperature of the mold during the pouring process is simulated by using the three-dimensional unsteady finite element heat transfer mathematical model to obtain the temperature field distribution and the change of the mold. At the same time, the influences of mold copper wall thickness and cooling water flow velocity on the mold temperature were studied. The field tests showed that the suitable wall thickness of the mold was 10mm and the appropriate cooling water flow rate was about 10m / s.
