APPLICATIONS

The vacuum atmosphere chamber furnace can operate under vacuum and protective atmosphere. It’s extensively used for heat treatment of materials like hard alloys, ceramics, and powder metallurgy materials. It can also treat high-speed steel, alloy grinding tools, soft magnetic alloys, and other materials through quenching, annealing, and brazing. The furnace has the ability to pass inert gas, and is designed with gas inlets and outlets to maintain a protective atmosphere around the sample at high temperatures. Gas flow control can be adjusted using single or multiple float flow meters.

standard features

• The outer casing of vacuum atmosphere chamber furnace 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 shell adopts a cylindrical tank design, double-door flange sealing structure, PTFE sealing ring, and the sealing vacuum can reach 0.1pa.
• 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.
• An intelligent 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℃.
• Heating rate of vacuum atmosphere chamber furnace is 1-25℃/min, a suggested 15℃/min heating rate for a long service life.
• 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 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
