Induction melting furnace for refining metal silicon from silicon mud

The metal silicon powder produced by silicon wafer manufacturers in the solar photovoltaic industry is dried and directly melted in the furnace after pretreatment. The melting cost is low, the consumables are few, no graphite crucible is needed, and the furnace lining has a long life and can be used continuously. Compared with the traditional electric furnace, the smelting cost can be saved by more than 40%.

Integrating the characteristics of metallic silicon, our company has developed a new type of special furnace for refining metallic silicon from silicon mud on the basis of a large number of experiments. It can directly smelt silicon mud with almost no loss. The yield rate is over 90%, and the product exceeds 2202.

The induction melting furnace for refining metal silicon from silicon mud is mainly composed of four parts:

1. Power supply and electrical part: parallel inverter intermediate frequency power supply or series inverter intermediate frequency power supply

2. Furnace body part: aluminum shell or steel shell, steel shell furnace body is composed of furnace shell, fixed frame, furnace cover, furnace tilting mechanism, induction coil, magnetic yoke, etc., and furnace leakage alarm device.

3. Transmission device: mechanical reducer or hydraulic device, etc.

4. Water cooling system: closed loop cooling tower
