How the Furnace Works
Step 1: Load Polysilicon Material
Polysilicon material is loaded into the crucible according to the required batch size.
Step 2: Vacuum and Inert Gas Protection
The furnace creates a high-vacuum environment and can use inert gas protection to reduce contamination during silicon processing.
Step 3: High-Temperature Melting
The furnace heats the silicon material up to 1600°C and turns it into molten silicon.
Step 4: Directional Solidification
The thermal field creates a controlled temperature gradient from top to bottom, helping the molten silicon solidify in one direction.
Step 5: Cooling and Ingot Output
After crystallization, tempering, and cooling, the final polysilicon ingot can be removed for downstream solar material use.
