Multi-Crystalline Ingot Furnace
The centrotherm multi-crystalline ingot furnace is designed for the production of multi-crystalline ingots from polysilicon pieces by directional solidification based on the vertical gradient-freeze method. The multi-crystalline ingot furnace consists of a stainless steel vacuum vessel with integrated water cooling. It contains an electro-mechanical opening and closing mechanism and comes with an integrated crucible loading tool. For process control it is fully automated and includes two independent adjustable heating zones.
- ingot weight up to 600 kg without feeding
- optimized hot zone for jumbo sized crucibles of 880 mm x 880 mm x 420 mm
- two independent adjustable heating zones and one integrated active cooling device for optimal process control
- Integrated loading and unloading tool
- full automation
- Option: Advanced Crucible Charging System
