What are the factors affecting the quality of vacuum sintering furnace production?

Vacuum sintering furnace production quality besides internal factors and there are many external factors, we take a look at what are the factors that affect the quality of vacuum furnace production.
Structure, temperature control of vacuum sintering furnace, heating process and furnace atmosphere etc., will directly affect the quality of the products after vacuum furnace production. Within the forging heating furnace, raise the temperature of metal, can reduce the melting resistance, but the temperature is too high will cause grain oxide or burnt, seriously affect the quality of the product in a vacuum furnace. In the process of heat treatment, if the steel is heated to above the critical temperature of a point, and then suddenly use cooling cooling, can improve the hardness and strength of steel; If heated to a temperature below the critical temperature at some point after slow cooling, the more resilient and make steel.
So if in order to obtain a more precise size of the workpiece and the surface is bright and clean, can adopt the way of no oxidation furnace for production, control of the oxidation burning loss of vacuum furnace is the key.
