2) Electro-Magnetic Casting Furnace

Application: This is a machine to produce rectangular silicon ingots by electro-magnetic casting method. The ingots are produced by high frequency induction coil heating in pressurized argon environment.

Features: Different from conventional casting method where impurities are included in ingots, this electro-magnetic casting method allows impurity-free casting without contacting a copper crucible.

Specification:
Ingot size: 110 mm x 1,000 mm
Main material: Silicon granules (φ0.5 mm ～ φ2.0 mm)
Melting temperature: 1,500 °C
In furnace environment: Argon purge after being vacuum (0.5 kg/cm2)
Casting speed: 0.5 ～ 5 mm/min.

Overall size: 2,430 m (D) x 1,520 mm (W) x 5,427 mm (H)
Weight: 7,500 kg excluding high frequency power supply, control panel and vacuum pumps.
