Definition: a furnace for sintering heated objects in a vacuum. There are many heating methods, such as resistance heating, induction heating, microwave heating and so on.
Objects: PM parts (mechanical parts, electrical parts, magnetic parts, cemented carbide parts, superalloy parts, refractory metal parts, etc.) are mainly sintered in resistance furnaces with controlled atmosphere and vacuum resistance furnaces. But in the high sintering temperature (500 ~ 2400 ℃), also use vacuum induction sintering, especially in the tool industry.
Vacuum induction sintering furnace equipment composition: vacuum induction sintering furnace
equipment is similar to crucible type central induction melting furnace. The furnace is usually made of a well or a bell. The well type furnace is simple in structure and the bell jar type furnace is convenient for loading and unloading workpieces. The protective body is composed of furnace shell, inductor, graphite tube, workpiece support, power supply device, insulation layer, water cooling system and ventilation system. The furnace shell is equipped with temperature measuring device, observation device, etc
It reduces harmful elements (water, oxygen, nitrogen and other impurities) in the atmosphere.
2. Improve alloy structure and properties.
3. Make materials denser.
Higher wear resistance and strength of the material.
5. The product cost has also been greatly reduced.
