    product description:
            KJ-V2200-160G vacuum hot pressing sintering furnace is a vertical vacuum resistance furnace that uses graphite as a heating element, with a frame-type double-pillar support outside. There is a hydraulic cylinder lifted and lowered as a pressure source for metal compounds, ceramics, inorganic compounds, nano materials, etc. to heat and press products in a vacuum or protective atmosphere.
    Structure and composition:
         KJ-V2200-160G vacuum hot pressing sintering furnace is mainly composed of furnace body, furnace cover, furnace cover lifting system, furnace bottom, heating and heat preservation and temperature measurement system, pressure system, vacuum system, water cooling system, control system, etc.
    Product Usage:
          KJ-V2200-160G vacuum hot pressing sintering furnace can combine vacuum/atmosphere, hot pressing forming and high temperature sintering. It is suitable for high temperature hot forming of new materials such as powder metallurgy and functional ceramics, such as transparent ceramics, industrial ceramics, etc. Vacuum sintering of metals and alloy materials composed of refractory metals and high-temperature sintering of ceramic materials silicon carbide and silicon nitride can also be used for the heat treatment of powder or compacts at a temperature lower than the melting point of the main components, with the purpose of passing particles Metallurgical bonding between to improve its strength.
        The structure design of KJ-V2200-160G vacuum hot pressing sintering furnace is advanced and reasonable, and the design and manufacturing meet the corresponding national and industry standards and specifications, and can meet the user's requirements. The energy saving effect of the equipment is good. It is convenient and simple to use, operate and maintain, beautiful in appearance, safe and reliable, and excellent after-sales service. The supporting products and components have the international advanced level, which can meet the long-term, stable, safe and reliable production demand.
