Vacuum Atmosphere Furnace – TT-VAF-36-1700
TT-VAF-36-1700 is a 1700°C vacuum atmosphere furnace designed to operate under both vacuum and controlled atmosphere conditions. It is commonly used for heat treatment processes involving hard alloys, ceramics, and powder metallurgy materials. Additional applications include vacuum quenching, annealing, processing of high-speed steel and alloy abrasives, brazing of soft magnetic materials, and other thermal treatment tasks.
Vacuum Atmosphere Furnace – TT-VAF-36-1700 Features
Furnace Shell
- Constructed from Q235 low-carbon steel with an electrostatically resistant, anti-corrosive finish.
- Durable metal shell design ensures low external surface temperature.
- Side-opening door with a flanged sealing structure and manual screw compression for easy and safe operation.
Refractory Material
- Features a multi-layer insulation system made from lightweight alumina ceramic fiber and premium insulation boards. This design is asbestos-free, reduces heat loss, and enhances energy efficiency.
Heating System
- Uses high-quality HRE spiral resistance wire heating elements, securely embedded in the chamber walls for efficient and uniform heat distribution. Long service life and energy-efficient.
- Heating is applied on three sides—left, right, and bottom—for consistent temperature uniformity.
- Silicon carbide base plate protects the bottom heating element, offering high mechanical strength, excellent thermal conductivity, and stable horizontal load support.
Temperature Control Panel
- Features a PID controller with SSR/SCR control modes for accurate temperature regulation.
- Equipped with a standard N-type nickel-chromium-silicon thermocouple, with a range of 0–1300°C and extended service life.
Program Controller
- Designed to support complex thermal processing needs.
- User-friendly interface with flexible programming options.
- Supports up to 4 curves and 8 segments per curve for detailed process customization.
- Includes over-temperature and fault alarms with built-in automatic safety protections.
Vacuum Atmosphere Function
- Furnace chamber includes adjustable gas inlet and outlet ports for introducing protective gases.
- Compatible with various vacuum pumps, achieving vacuum levels between 500 Pa and 0.06 Pa, displayed via a digital vacuum gauge.
- Optional gas control unit available, offering 1 to 3 adjustable flow meters for precise control.
