Product Description

Industrial Vacuum Resistance Furnace for Polysilicon & Rare Earth Sintering

Description:                                                                                                                       

  • Crafted for large-scale industrial production, this 1-to-1 vacuum resistance furnace reaches 2200℃, combining sealed vacuum technology with high-efficiency resistance heating to maintain stable temperature conditions for bulk workpieces. It operates on 380V 3-phase power with thyristor control, ensuring reliable performance during extended production runs.
  • Its rugged industrial structure resists wear from continuous operation, while the intelligent temperature regulation system precisely controls thermal processes to ensure uniform heating of polysilicon, rare earth oxides, and other high-value materials. This design maximizes product consistency and yield for high-precision manufacturing.
  • Equipped with comprehensive safety features and an intuitive operation interface, it minimizes operational complexity and risk, making it perfect for mass production of polysilicon for semiconductors, rare earth materials for advanced alloys, and carbon composites.

Application:                                                                                                                        

  • Polysilicon Production: Large-batch sintering of polysilicon for solar cell and semiconductor manufacturing.
  • Rare Earth Processing: Continuous heat treatment of rare earth oxides for advanced material and magnet production.
  • Carbon Composite Manufacturing: High-volume processing of graphite and radiation-proof materials for industrial components.
