VQB small vacuum brazing furnace

VQB small vacuum brazing furnace was applied for aerospace, aviation, electronic industries components treatment. It takes double layers water cooling, electronic lifting, bell type stainless steel structure, three zones Y type heating, with water cooling full metal heat insulation wall, auto temperature control, all processes can be controlled by computer.
Ultimate vacuum : 1 x 10-5Pa
Working vacuum：system expose in ATM condition in short time then charging dry N gas and degassing, the vacuum degree can achieve 1 x 10-4Pa in 60 min.
Pressure rising rate of system: ≤0.2 Pa/h ( average value after pump closed 12 hours)
Working zone dimension: vertical hating zone Φ300 x 350mm(h); temp uniformity zone Φ200 X250mm
Working zone temperature: Max heating temp 1000C; rated heating temp range~ 850C; temp uniformity ±3C
Working zone heating control method: programmable auto control, process control, monitor, data collection and treatment by computer auto control.
Temperature control accuracy: constant temp zone ±3C
Thermocouple temperature measuring accuracy: ＜1C
One way process gas path matched, quality flow gauge adjust gas flow.
