Normantherm vacuum furnace is specialized in vacuum heat treatment technology

Vacuum Brazing Furnace 222


Our Brand:ACX

Category:Vacuum brazing furnace

Applications:This equipment is mainly used for the high vacuum heat treatment of metal materials. Main application industries and processes: diamond vacuum brazing, stainless steel vacuum brazing, titanium alloy vacuum brazing, hard alloy, and PCD tool brazing, etc

Main Features:Heating zone: 410×390 (L×ø) mm. Max. temperature: 1300°C. Ultimate Vacuum: ≤5.0*10-4 Pa. The equipment occupies less space, is easy to operate, has advantage of high efficiency, pollution free, low energy consumption, and low noise. Good welding quality, high strength, and strong stability. Rising from room temperature to 1000℃ is less than 90min (empty furnace), suggest 10℃/min, the fastest is ≤20℃/min.

Detailed introduction


Technical Details:

Furnace structure: horizontal,   single-chamber, furnace body and door adopt double-layer water cooling, front door structure. It is composed of a furnace body, heating chamber, vacuum system, charging system, water cooling system, electric control, and power supply system.

The heating chamber adopts a cylindrical heating chamber structure. The heat shield adopts a multi-layer molybdenum structure, and high-quality 99 corundum ceramics are used between the layers.   The heating element is molybdenum sheets, which are evenly surrounded by the heat shield to achieve good temperature uniformity. It has a long service life, good heat insulation performance, and minimal vacuum outgassing. The outer frame is made of stainless steel (310S) plate material, and multiple reinforcement ribs are welded to ensure no deformation.

Heating control adopts PID intelligent temperature control module design, can edit a 30-segment heating curve, store   20 sets of process formulas, combine PLC to realize automatic alarm protection functions such as overpressure, over-temperature, over-current,   10-inch LCD touch screen display operation, with Convenient operation,   powerful functions, and good stability.
