Vacuum Annealing Furnace
This vacuum annealing furnace uses resistance wire radiation heating. The furnace chamber uses a 310S stainless steel liner, which has good oxidation resistance and high cleanliness. The insulation material uses ceramic fiber wool, which has good thermal insulation performance and high efficiency, and energy saving. It is suitable for metal annealing, ceramic sintering, vacuum smelting, electric vacuum parts degassing, annealing, brazing of metal parts, and ceramic-metal sealing.
