摘要
为了提高多晶硅铸锭炉生产效率,在450 kg铸锭炉炉体不变的基础上,利用有限元方法对其热场结构进行优化,使坩埚装料量达到550 kg。对优化后热场模型进行数值计算,550 kg硅料完全熔化需要19.3 h,每小时可熔化硅料28.5 kg。通过对计算结果分析,确定优化后热场可以使硅料完全熔化,且单位质量硅料熔化时间减少,提高了铸锭炉生产效率。
In order to improve the production efficiency of multicrystalline silicon ingot furnace, based on 450 kg multicrystalline silicon ingot furnace, the thermal system of the 450 kg ingot furnace is optimized using finite element method. After optimization, the crucible of 450 kg ingot furnace can be filled with silicon of 550 kg. The numerical simulation of the optimized model is conducted, the silicon of 550 kg can be melted in 19.3 h, and 28.5 kg silicon can be melted in 1 h. The analysis show that the silicon in the furnace will be melted completely, and the melting time of silicon material of unit mass can be shortened, the production efficiency of ingot furnace can be improved.
