Application
1. It is used in sintering the electrical vacuum devices in hydrogen.
2. The sintering of powder metallurgy parts and pottery materials.
3. High-temperature sintering of hard alloy.
Characteristics
1. There are two kinds of vacuum sintering furnace—graphite flue and metal flue.
Graphite flue is often chosen as the material with graphite rod as the heating
material and heat screen is generally made of multilayer graphite felt and pottery
felt. Metal flue is exclusively applied in sintering special materials. The heating
material of metal flue is molybdenum and tungsten and heat screen is made of
molybdenum, tungsten and stainless steel.
2. The system is controlled by PLC and touch screen shows the working condition. It is
easy to choose the manual operation or the automatic operation. The alarm system
responds automatically if the numerical value of temperature, water pressure or air
pressure is found greater than setting value
