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.

Tube furnaces have been the backbone of high-temperature processing for decades — yet the gap between a well-specified unit and a poorly matched one can mean the difference between consistent results and costly failures. Whether you're sintering advanced ceramics, conducting CVD experiments, or processing alloys under controlled atmospheres, understanding what separates a capable high temperature tube furnace from one that merely gets hot is essential before you commit to a purchase.
