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.

1、 Shaped ceramic fiber furnace lining for high alumina ceramic fiber board The shaped ceramic fiber furnace lining of high alumina ceramic fiber board mainly refers to the furnace lining composed of formed refractory materials such as fiber blankets, fiber felt, fiber boards or fiber components. Structurally, it can be divided into two categories: layered structure and composite structure. 1. Structure of Layered Refractory Fiber Lining Layered laying of refractory fiber furnace lining is...
