APPLICATIONS

The low vacuum atmosphere furnace features a flange sealing structure. This allows the introduction of protective atmospheres like nitrogen, argon, and oxygen during material heat treatment. It is suitable for the heat treatment of carbon, metal, and biomass materials. Additionally, it can be used for the sintering of ternary materials in lithium batteries.

standard features

• The stove’s outer casing is made of Q235 low carbon steel, featuring electrostatic and corrosion resistance on the surface. It has a sturdy metal frame shell structure, with a low furnace surface temperature.
• The chamber is insulated with alumina ceramic fiber for maximum temperature stability and uniformity, as well as low energy consumption.
• The furnace door adopts a flange structure, with PTFE sealing rings and a spiral compression device, providing good sealing.
• The atmosphere furnace can operate under vacuum, with a vacuum degree of -0.1Mpa. It is less expensive than a vacuum furnace, making it a cost-effective option.
• The furnace top is equipped with a water cooling system. This effectively reduces the heat dissipation temperature, ensuring the normal operation of the heating element.
• High-quality heating elements provide excellent temperature uniformity, offer fast heat-up and cool-down rates, and ensure unsurpassed temperature uniformity along the entire heated length.
• Heating rate is 1-25℃/min, a suggested 15℃/min heating rate for a long service life.
• An intelligent microcomputer-based self-tuning PID temperature controller, with SCR/SSR control, can set the heating curve and program 4 groups of 30 segments for program heating, program heat preservation, and program cooling.
• The temperature control is precise, with minimal temperature fluctuations. It includes temperature compensation and calibration functions, with an accuracy of ±1℃.
• The device features a circuit breaker that trips automatically during a leakage or short circuit, safeguarding both equipment and operators.
• The furnace emits an alarm signal and automatically protects when overheated or when the thermocouple breaks during the working process.
• The integrated design of the atmosphere furnace furnace cover enables easy sample placement and quick cooling.
• Standard configurations: Furnace body -1 set, Thermocouple -1 set, Manual -1 copy, Temperature controller -1 set, High temperature gloves -1 pair, Crucible Tong -1 set
• Optional accessories:
  • Optional float flowmeter
  • Optional gas mixing device
  • Automatic power off when furnace door opens
  • Paperless recorder
  • Exhaust chimney
  • Alumina crucibles
• Quality Certificates: CE, SGS, ISO9001, TUV
• Warranty: one year，life long technical support
