摘要
报道了太阳能级硅的电磁约束感应熔炼技术（ＥＩＭ）。依据电磁悬浮熔炼原理，在磁悬浮技术的基础上，把电磁悬浮熔炼技术和冷坩埚熔炼技术相结合，通过感应线圈、石墨预热环、Ａｌ２Ｏ３隔热环及水冷铜支架等的设计，成功地熔化了重为１０ｇ的硅试样，熔化过热度高达２００℃。该技术具有熔化能力大、过热度高、二次污染少、定量浇注及节约硅材料等优点，基本满足了离心铸造法制硅片对熔化的要求。
he Electromagnetic-confined Induction Melting (ElM) technique of solar-grade silicon isproposed. With the induction coil, the preheating graphite circlet, the heatresisting Al2O3 circlet and the water-cooled copper support, 10 grams silicon charge is successfully melted,and the preheating temperature is 200℃ higher than the melting point. The EIM technique has the advantages of uncontaminated melting, high superheating temperature,large melting capacity, guantitatlve pouring and low silicon material depleting, all of which satisfied the needs on melting of the spinning casting method to produce low-cost silicon sheets.
