Vacuum Brazing Furnace

真空钎焊炉

Heat exchangers, aerospace assemblies and carbide tools all depend on clean, even brazed joints. Uniformity of ±3–5 C across 2–3 zones and vacuum to 0.001 Pa make this furnace suited to that work, up to 800–1200 C. Hot zones reach 900×900×1200 mm. Cooling uses inert backfill or forced gas; tell us your filler alloy and fixture size.

Hot zone size: 400×400×600 to 900×900×1200 mm
Maximum temperature: 800–1200 C
Working vacuum: 0.001–10 Pa
Hot zone material: Graphite felt or molybdenum shield
Temperature uniformity: ±3–5 C
