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.
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.
