Low Temperature Vacuum Annealing Furnace
This equipment is a horizontal structure with a square structure in the middle of a circle, which can ensure high vacuum efficiency while also making the furnace resistant to deformation and durable. The finned metal tube is heated inside, and the heat is evenly distributed with a multi-layer heat insulation screen. The furnace uses a 304 stainless steel furnace and a carbon steel outer layer. The two layers are cooled with circulating water, which has a long service life. It is mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing.

In high-temperature industrial environments, material selection can make or break the efficiency, safety, and longevity of thermal equipment. The ceramic fiber tube has emerged as a premier refractory solution across industries ranging from metallurgy and petrochemicals to glass manufacturing and heat treatment. Unlike conventional refractory materials, ceramic fiber tubes combine structural integrity with outstanding insulation performance, making them an indispensable component in modern indus...
