Zhengzhou Protech Manufacturing Co., Ltd., said in a vacuum atmosphere furnace atmosphere furnace is an object in the through the use of certain gases into the sintering furnace atmosphere furnace method of product, in the vacuum sintering, often volatile metal loss occurs, for containing decarbonization carbon material can be used to increase the carbon content of the powder feed and control the vacuum to be resolved. Here to talk about the advantage of the characteristics of a vacuum atmosphere furnace:
1, during operation of the furnace atmosphere should not be used as a reducing or inert gas protective atmosphere sintering.
2, vacuum furnace atmosphere conducive to shrink and be able to improve the organization of the alloy, optimizing the relative wettability of the solid phase.
3, vacuum sintering furnace atmosphere process reduces the adverse effects of the atmosphere (water, oxygen, nitrogen) harmful ingredients of the product.
4, vacuum sintering helps to eliminate silicon, aluminum, magnesium, calcium oxide, or impurity, purify the material role.
5, a vacuum atmosphere in the furnace in a vacuum atmosphere conducive to exclude adsorbed gas, the residual gas in the pores and the reaction product gas, the porosity of the sintered cemented carbide vacuum is significantly lower than the cemented carbide sintered in hydrogen.
6, the sintering temperature vacuum atmosphere vacuum furnace gas than the sintering temperature is lower, so the cemented carbide the sintering temperature can be reduced 100 ~ 150 ℃. This helps to reduce energy consumption and prevent grain growth.
