    Product introduction:
    The double-tube tube furnace equipment is a new generation product developed by our company. The specifications can be customized according to user requirements. Two furnace tubes can be placed up and down in a heating chamber. The furnace material is made of high-purity alumina polycrystalline fiber and double-layered shell. Body structure, beautiful appearance, compact structure, can be made into single temperature zone, double temperature zone, multi-temperature zone, etc. The temperature control system adopts PID intelligent program temperature control system, thyristor control, high temperature control accuracy, each temperature The temperature of the zone can be controlled independently, mainly used in college laboratories, industrial and mining enterprise laboratories, high, medium and low temperature CVD processes, such as the development of carbon nanotubes, crystalline silicon substrate coating, metal material diffusion welding and vacuum or atmosphere. heat treatment, etc.

    Main functions and features:
    1. The heating element adopts high-quality silicon molybdenum rod, and the furnace insulation material adopts polycrystalline fiber material, which has good thermal insulation performance, durability, high tensile strength, no foreign balls, high purity, and the energy saving effect is obviously better than that of domestic fiber materials.
    2. The whole furnace body adopts a double-layer liner structure with an air gap in the middle. Even if the furnace temperature is as high as 1600 ℃, the surface of the furnace body can still be safely touched without a feeling of burning.
    3. The heating element adopts high-quality silicon molybdenum rod, which has a fast heating rate and is convenient for later replacement and maintenance.
    4. The temperature control system adopts artificial intelligence adjustment, has PID adjustment, self-tuning function, and can compile 30 sections of heating and cooling programs
    5. Five temperature zones are used for heating, each temperature zone is 300mm long, and each temperature zone can independently control the temperature
    6. Independent electric control cabinet, output voltage and output current monitoring table, the heating state of the furnace is clear at a glance.
    7. With over-temperature alarm protection function, safe and reliable operation
    8. Our company has the ability to develop, design, produce and process by ourselves, and our machines provide lifetime parts replacement and upgrade services.
