Oxygen Free Vacuum Annealing Furnace
This oxygen-free vacuum annealing furnace uses silicon-molybdenum rod internal heating, a square structure in a circle, uniform heating, good pressure resistance, and can achieve high-temperature sintering in a completely oxygen-free state. The furnace chamber uses ceramic alumina fiber, which has good thermal insulation performance and high cleanliness. It is suitable for metal annealing, ceramic sintering, vacuum smelting, electric vacuum parts degassing, annealing, brazing of metal parts, and ceramic-metal sealing.
