摘　　要：泡生法蓝宝石单晶炉的隔热系统通常采用多层钼隔热屏的形式,虽可满足结晶要求,但是热量损失比较严重。经过数值模拟分析,在侧边加入氧化锆隔热层可明显减少热量损失,达到良好的隔热保温效果。同时缩短了晶体生长周期,达到了节省电能的目的。The insulation systems of Kyropoulos sapphire crystal fumace typically use multi--molybdenum heat shield form, although it can meet the requirements of crystallization process, but the heat loss is more serious. Through numerical simulation analysis, we find that adding zirconia insulating layer in the side of furnace can significantly reduce heat loss and achieve good thermal insulation effect, while reducing the crystal growth cycle and also reaching the purpose of saving energy.
