Product Details
WOLFU polysilicon directional solidification furnace is designed for high-temperature melting, purification, and directional solidification of silicon materials used in solar photovoltaic applications. It is widely used for producing polycrystalline silicon ingots for solar cells and semiconductor materials.
This equipment adopts a vertical furnace structure and integrates functions such as high vacuum operation, inert gas protection, high-temperature melting, and controlled directional solidification. The furnace allows precise control of the temperature gradient, enabling stable crystal growth and improved material purity during the solidification process.
The system uses PLC and HMI control for full automation, allowing operators to complete the entire process with minimal manual intervention. The patented thermal field structure creates a larger temperature gradient from top to bottom, improving crystal quality and supporting purification during ingot formation.
Even when using raw materials of lower purity (such as 4N), the furnace can help achieve higher purity silicon (above 5N) through controlled crystallization. This makes it a practical solution for solar silicon ingot production and advanced material processing.
WOLFU provides customized furnace solutions based on crucible capacity, production scale, vacuum requirements, and plant layout. The system can also be integrated with additional heat sources or purification modules depending on the process requirements.
