KJ-V220W-G vacuum hot pressing furnace is a complete set of equipment for hot pressing materials under vacuum (or other atmosphere) conditions. It mainly uses resistance heating and the pressure head driven by an oil cylinder is pressurized up and down. Under high temperature, the solid particles of the green body are interconnected, the crystal grains grow, the voids (pores) and the grain boundaries gradually decrease. Through the transfer of the material, the total volume shrinks and the density increases, and finally becomes a kind of microstructure. The structure of the dense polycrystalline sintered body, so as to press the material into shape.
Structure and composition:
Vacuum hot pressing furnace is mainly composed of furnace body, furnace cover, furnace cover lifting system, furnace bottom, heating and heat preservation and temperature measurement system, pressurization system, vacuum system, water cooling system, control system, etc.
KJ-V220W-G vacuum hot pressing furnace can combine vacuum/atmosphere, hot pressing forming and high temperature sintering. It is suitable for high temperature heat forming of new materials such as powder metallurgy and functional ceramics, such as transparent ceramics, industrial ceramics and other metals. As well as the vacuum sintering of alloy materials composed of refractory metals and the high-temperature sintering of ceramic materials silicon carbide and silicon nitride, it can also be used for the heat treatment of powder or compacts at a temperature lower than the melting point of the main component. The purpose is to pass between particles The metallurgical combination to improve its strength.
The structure design of the KJ-V220W-G vacuum hot pressing furnace is advanced and reasonable, and the design and manufacturing conform to 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.
