    Product introduction:
      This customized high-temperature atmosphere furnace is mainly used in college laboratories, industrial and mining enterprise laboratories, for chemical analysis, physical determination, sintering and dissolution of metals, ceramics, etc., used in electronic components, powder metallurgy, magnetic materials, quartz materials The debinding, pre-firing and firing of other products can also be used for heat treatment processes of other materials. The furnace body adopts a double-layer furnace shell structure, high-performance heat insulation material, and is equipped with a cooling fan, which makes the surface temperature of the furnace body lower and saves 60% energy compared with ordinary furnaces. The furnace door and furnace roof are sealed with high-temperature silicone rubber, which can be pre-evacuated and can be introduced into a variety of inert gases.
       It adopts double shell structure and intelligent program temperature control system, phase shift trigger, SCR control, and the furnace adopts oxidation. Aluminum polycrystalline fiber material, double-layer furnace shell is equipped with an air cooling system, the furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall, and energy saving.
    Structural composition:
    The customized high-temperature atmosphere furnace consists of a high-temperature atmosphere furnace, a gas supply system and an exhaust gas treatment device.

    Please pay special attention to: H2 is a particularly flammable and explosive gas. Its combustion temperature is 400 ℃. It will explode when the mixing ratio with air reaches 4.0%-74.2% , so safety measures must be taken when using hydrogen.

    The maximum pressure that can withstand in the furnace is 0.03MPa , so a pressure reducing valve must be installed on the gas cylinder when gas is introduced into the furnace.

    Before entering hydrogen, inert gas must be used to clean the furnace. The pressure inside the furnace should always be kept between 0.01-0.02 Mpa during use to prevent air from flowing back into the furnace and causing an explosion.

    The room where the equipment is placed must be well ventilated.


    The discharged hydrogen must be combusted indoors (the top of the furnace body is equipped with an automatic ignition device) In order to keep the pressure in the furnace chamber relatively stable during the heating process, we recommend that the equipment increase

    Temperature rate is less than 10 ℃ /min
