    KJ-A1600-64CZ Series high temperature Inert Atmosphere Furnace is mainly used in college laboratories, industrial and mining enterprise laboratories, for chemical analysis, physical measurement and sintering and dissolution of metals, ceramics, etc.

    Product Introduction:
    KJ-A1600-64CZ Series high temperature Inert Atmosphere Furnace is mainly used in college laboratories, industrial and mining enterprise laboratories, for chemical analysis, physical measurement and sintering and dissolution of metals, ceramics, etc., used in electronic components, powder metallurgy, magnetic materials, quartz materials and other products It can also be used for heat treatment of other materials etc. The furnace body adopts a double-layer furnace shell structure, high-performance heat insulation material, and is equipped with a cooling fan, so that the surface temperature of the furnace body is low, and the energy saving is 60% compared with ordinary furnaces. The furnace door and furnace top are sealed with high-temperature silicone rubber, which can be pre-evacuated and can be fed with various inert gases.
    It adopts double-layer shell structure and intelligent program temperature control system, phase-shift trigger and thyristor control. The furnace is made of alumina polycrystalline fiber material. The double-layer furnace shell is equipped with an air-cooling system. It has the advantages of low surface temperature, fast temperature rises and fall rate, and energy saving.

    Main technical requirements:
    1. Max Temperature: 1700℃
    2. Working Temperature: 1600℃
    3. Temperature Controller: 30-segment programmable PID intelligent control, phase-shift trigger.
    4. Chamber size: 400*400*400mm
    5. Furnace structure: double-layer shell with built-in air-cooling structure
    6. Temperature control protection: With over-temperature, thermocouple broken protection function
    7. Vacuum atmosphere: Nitrogen, Argon, Oxygen and other gases can be passed through, and it can be evacuated.
    8. Ultimate vacuum degree: -0.1MPa
    Float flow meter: Nitrogen Gas(30-300ml/min or base on your request)

    Main functions and features:
    1. The furnace adopts high-quality alumina polycrystalline fiber inorganic material formed by vacuum adsorption with Japanese technology, which has good thermal insulation performance, durability, high tensile strength, no foreign balls, high purity, and energy saving effect is obviously better than other fiber materials;
    2. The entire furnace body adopts a double-layer liner structure with an air gap in the middle. Even if the furnace temperature reaches the highest, the surface of the furnace body can still be safely touched without a burning feeling.
    3. The furnace is made of energy-saving materials, and the energy consumption of the whole machine is only 1/3 of the same traditional electric furnace, which is energy-saving and environmentally friendly.
    4. The furnace body is equipped with: output voltage and output current monitoring table, the heating state of the furnace is clear at a glance.
    5. Over-temperature alarm power-off function and leakage protection measures, safe and reliable operation.
