Example Embodiment
[0023] The present invention will be specifically introduced below in conjunction with the drawings and embodiments.
[0024] Such as Figure 2-5 Shown: This embodiment is an ingot furnace that improves the average conversion efficiency of silicon ingots. It includes a furnace body 1 and a crucible 5 arranged inside the furnace body 1. The crucible 5 in this embodiment is made of quartz material, and the silicon ingot 6 is located In the crucible 5, a graphite column 14 is vertically arranged at the bottom of the furnace body 1, and a heat exchange platform 12 is horizontally arranged on the top of the graphite column 14. The crucible 5 is placed on the heat exchange platform 12, and the heat exchange platform 12 mainly performs heat transfer. Between the periphery of the crucible 5 and the inner wall surface of the furnace body 1, a graphite guard layer 4, a heater layer 3 and a heat preservation cover layer 2 are sequentially arranged between the periphery of the crucible 5 and...
