Vacuum brazing refers to a welding process in which a group of weldments are heated to above the melting point temperature of the filler metal, but lower than the melting point temperature of the base metal, and the weld is formed by the wetting and flow of the filler metal to the base metal (the brazing temperature varies with the material).
Vacuum sintering is a method of heating metal powder products under vacuum to make adjacent metal powder grains sintered into parts through adhesion and diffusion.
Vacuum magnetization is mainly applicable to magnetic treatment of metal materials.
Advantages of vacuum furnace:
1) The oxidation and decarburization of the workpiece surface during the heating process are completely eliminated, and a clean surface without deterioration layer can be obtained. This is of great importance to the improvement of the cutting performance of tools that grind only one side (such as fried dough twist drills that expose the decarburized layer on the groove surface directly to the edge after grinding).
2) It has no pollution to the environment and does not need to be treated with three wastes.
3) The accuracy of furnace temperature measurement and monitoring has been significantly improved. The indicated value of thermocouple and furnace temperature reach ± 1.5 ° C. However, the temperature difference in different parts of a large number of workpieces in the furnace is large. If the forced circulation of dilute gas is adopted, the temperature difference can still be controlled within ± 5 ° C.
