Introduction
Vacuum gas quenching furnace is mainly used for vacuum bright quenching, sintering, brazing, etc. of tool steel, mold steel, elastic alloy, stainless steel, and 3D printing additives. It is mainly composed of a pressure furnace body, a heating chamber, a vacuum system, an electronic control system, an air filling system, a water cooling system, a pneumatic system and a transport vehicle outside the furnace.
Features
● The heating chamber is composed of graphite heating body, graphite soft felt and hard felt. The maximum operating temperature can reach 1350℃.
● Multiple rows of graphite nozzles are evenly distributed in the heating chamber along the circumferential direction of the inner wall of the insulation layer. During gas quenching, the gas is forced to eject evenly from the graphite nozzle, effectively achieving uniform quenching.
● The material table consists of graphite pillars, graphite hearth and AL2O3 spacers on the hearth. This structure can prevent the material tray and graphite hearth from adhering at high temperatures.
● The thermal field can also be heated with high-temperature molybdenum belts and molybdenum foil heat shield furnaces. This thermal field has no volatilization, no impurities, and no pollution to the heat treatment workpiece.
● Air cooling system: At the rear of the furnace body, there is a high-pressure impeller fan, a multi-stage high-efficiency copper heat exchanger and an air duct diversion device. During air cooling, high-purity nitrogen or high-purity argon is charged. Driven by the high-speed impeller fan, the gas is sucked into the impeller through the high-efficiency copper heat exchanger, rotates through the impeller, and is evenly distributed through the air duct guide device. The graphite nozzle sprays towards the workpiece to forcefully cool the workpiece evenly.
● The air cooling pressure can be adjusted arbitrarily from 1-10bar.
● Maximum cooling rate: cooling an empty furnace from 1150°C to 250°C in less than 7 minutes (cooling water temperature is less than 35°C).
