AE-270/450 polycrystalline silicon ingot furnace adopts various kinds of new technologies, and with the advantages of a larger loading and a higher productivity. The adoption of special ceramic fiber and the double safety protection design of graphite hard felt will guarantee that the emergency measures for silicon leakage can be started promptly with the automatic induction system of silicon leakage. The excellent safety performance of this furnace can reduce the potential accidents greatly. The heating system with high performance can guarantee the uniformity and consistency of silicon during the crystallization process. The operation process adopts PLC control, high-speed microprocessor testing and processing elements, dynamic detecting and high-speed response, and it has realized the automatic control and data exchange in the whole process. Therefore, this furnace takes the advantages of high efficiency, high stability, high reliability and good anti-jamming. What¡¯s more, its control system is equipped with single-phase UPS devices, which can reduce the loss coursed by instant power interruptions. Polycrystalline silicon ingot furnace is an important production equipment in the field that generates electricity though solar photovoltaic, it is also a kind of polycrystalline silicon ingot casting equipment which is developed to meet the needs of solar battery market. Putting the materials such as polycrystalline silicon pieces, end-wastage, crucible base material and various kinds of mono-crystal waste pieces into the quartz crucible of the furnace, and after the relevant process of melting, re-directed crystallization and annealing, it can cast the preliminary raw material of solar battery, what we called polycrystalline silicon ingots.
