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.

A seven-zone mesh belt furnace running at 1120 °C can hold ±3 °C across the belt and still ship parts with inconsistent hardness, because the dew point in the delubrication zone drifted after the belt speed was raised. That is the nature of powder metallurgy: the furnace is not a box that gets hot, it is a chemical reactor with a conveyor attached. The short answer: select a powder metallurgy furnace by the process window it must hold — delubrication profile, atmosphere quality, sintering tempe...
