摘要
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 view of quality and productivity, the heat transfer of mould is critical during continuous casting. According to the characteristics, a three - dimention heat - transfer mathematical model has been used to simulate the temperature field of billet mould.The temperature distribution of mould is then obtained and the effects of the parameters such as mould wall thickness and cooling water rate, are studied. It is proved that the suitable mould wall thickness is 10mm and the suitable cooling water rate is 10m/s.
