    Tungsten And Molybdenum Heat Shield For Vacuum Furnace


    1. Description of Tungsten And Molybdenum Heat Shield For Vacuum Furnace:


    Molybdenum metal and graphite can also be used for insulating parts of vacuum furnaces. In an all-metal thermal field, the heat shield is composed of multiple layers of metal plates, with a certain space reserved between each layer of heat shield.Molybdenum and tungsten have a lot of the same characteristics as each other, including a high boiling point, excellent electrical conductivity, and a low linear thermal expansion coefficient that makes processing molybdenum easier than tungsten.


    The thermal conductivity of metallic molybdenum [135 W/(m·K)] is optimally matched with the specific heat [0.276 kJ/(kg·K)], making it a natural choice for thermal shock and thermal fatigue resistance. Its melting point is 2620°C, second to tungsten and tantalum, but its density is much lower, so its specific strength (strength/density) is higher than that of tungsten, tantalum and other metals. efficient. Molybdenum still has high strength at 1200℃.


    Molybdenum heat shield has the following characteristics: small coefficient of linear thermal expansion, easy processing, low thermal conductivity, and small specific heat.


    2. Size and Tolerance of Tungsten And Molybdenum Heat Shield For Vacuum Furnace:


    Unit:mm

    ThicknessMax diameter
    2.0±0.1660±0.2
    1.0±0.08660±0.2
    0.5±0.04660±0.2
    0.3±0.03660±0.2

    Special sizes can be manufactured based on customers' requirements.



    3. Types of Tungsten And Molybdenum Heat Shield For Vacuum Furnace:


    Cylindrical side heat shields and truncated end heat shields (upper and lower heat shields)


    Side heat shield is usually made of molybdenum plate or molybdenum alloy plate


    The end heat shield is assembled from molybdenum plate, tungsten plate and other tungsten and molybdenum parts


    4. Use Applictaion of Tungsten And Molybdenum Heat Shield For Vacuum Furnace:

    Uses: Mainly used in vacuum furnaces, etc., to heat insulation and reflect heat.
    Type: mainly divided into welding heat shield, riveted heat shield
    Material: Grade: MO1 Molybdenum content ≥: 99.95 (%)
    Impurity content: 0.05 (%)
