Vacuum hot pressing furnace
Product introduction:
The vacuum hot pressing sintering furnace consists of a furnace body, a vacuum system, a pressurizing system, a control system, a hot zone, a gas system, etc. This equipment can be used for the sintering of metal, ceramic and some refractory metal intermediate compound powders. The advantage of hot pressing sintering is that the equipment investment is small (compared to hot isostatic pressing). Since a high vacuum degree is maintained during the hot pressing process, the sintering temperature of the product can be effectively reduced and the gas in the tiny pores can be removed, thereby further promoting the densification of the hot pressed material.
The main advantages of the vacuum hot pressing sintering furnace include:
1. It is conducive to the removal of adsorbed gas and has a significant promoting effect on the shrinkage in the later stage of sintering.
2.It is conducive to the removal of impurities such as silicon, aluminum, magnesium, calcium and their oxides, and plays a role in purifying materials.
3.It can improve the wettability of liquid phase sintering, facilitate the shrinkage during the sintering process, and improve the structure of the alloy.
4.Vacuum is an ideal inert gas. When other primary or inert gases are not suitable, or the material is prone to decarburization and carburization, a vacuum hot pressing sintering furnace can be used.
5.Reduce the pollution of harmful components (water, oxygen, nitrogen, etc.) in the atmosphere to the product.
Purpose of vacuum hot pressing furnace:
Vacuum hot pressing furnace is a vacuum electric furnace that uses thermal energy and mechanical energy to improve the density of materials. It can perform vacuum hot pressing sintering below 2300℃ and protective atmosphere hot pressing sintering below 2400℃. It is mainly suitable for sintering and recrystallization of ceramics, cemented carbide, artificial diamonds and tools under high temperature and high pressure in teaching, scientific research and production scenarios, as well as heating and pressing of refractory metals, ceramics, etc. in a protective atmosphere.
