Introduction of heating chamber and furnace body of vacuum hot press furnace

Vacuum hot press furnace is a periodic operation type, which is widely used in hard alloy, functional ceramics, powder metallurgy and so on for hot pressing sintering under high temperature and high vacuum conditions. It can also be hot pressing sintering under the condition of inflating protection.

For vacuum or protective atmosphere, the structure of the hexahedral cube; The heater is made of high-density graphite, the structure form is heterosexual plate, and the distribution mode is six-sided uniform cloth. The insulation layer, from the inside out hard carbon felt (40mm), soft carbon felt (80) Mullite insulation felt (40mm), the outer layer is stainless steel shell (304); In order to facilitate material entry and exit, the front door of the heating chamber is opened, and the front door of the heating chamber is connected with the furnace door, and the material is discharged horizontally; Easy replacement of heating element. The whole heating area can be disassembled as a complete structural component for easy maintenance and repair;

Furnace body:

Horizontal installation, the front door; The furnace body is a double-layer structure (the inner layer is stainless steel, the outer layer is carbon steel), and the intermediate cooling water is passed to cool the furnace body. Internal polishing according to high vacuum requirements, external spray paint; The furnace body is provided with a vacuum interface, upper and lower pressure head device (water cooling, dynamic seal), electrode introduction device (water cooling, copper), thermocouple and optical temperature measuring device, inflating device, exhaust device; The furnace door is provided with an electrode introduction device (to supply power to the heater on the furnace door); The connecting structure of the furnace body and the furnace door is in the form of flange, and the handwheel bolt is locked. Lip seal ring better guarantee vacuum seal.
