Where is a good vacuum directional furnace

Vacuum furnace is a complete set of equipment for hot pressing of materials under vacuum (or other atmosphere). It mainly uses resistance or induction heating and presses up and down the pressure head driven by oil cylinder. At high temperature, the solid particles of green billet bond with each other, grain growth, voids (pore) and grain boundaries decrease gradually. Through material transfer, the total volume shrinkage and density increase, and finally become a compact polycrystalline sintered body with some microstructures, thus the material is compacted and formed. The simultaneous action of high temperature, pressure and vacuum or atmosphere can significantly improve the density, hardness and other mechanical, electronic and thermal properties of the product.


Where is the vacuum directional furnace? Advanced polycrystalline silicon directional solidification technology in vacuum directional furnace; high quality furnace material and high air-tight chamber provide excellent conditions for the growth of polycrystalline silicon; synchronous lifting technology of insulating cage, which is good for vacuum directional furnace, ensures vertical temperature gradient and solid-liquid interface level; convenient thermal field design for forming vertical temperature gradient, true. Where is the best way to achieve rapid crystal growth in an empty directional furnace? Maintain the design of auxiliary pumps during the unique growth period, which greatly reduces the energy consumption of vacuum system, prolongs the life of main pumps and reduces the cost of operation and maintenance.
