Stainless Steel 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 furnace is made of 310S stainless steel, which has good temperature resistance and strong pressure bearing capacity. The outer layer is carbon steel, and the two layers are cooled by circulating water, which has a long service life. It is mainly used for vacuum annealing of special materials, stainless steel, selenium steel sheet core, precious metal parts, silver-copper composite rivets and sheet parts.

A 20-tonne Acheson graphitization furnace can hold full power for 24 to 40 hours and then need five to seven days of cooling before anyone opens it. Peak temperature is the headline number, but cost per tonne is decided by three quieter things: the furnace type, the condition of the insulation, and the shape of the power profile. Two shops running the same 2800 °C schedule can differ by 30 percent in kilowatt-hours per tonne. The gap is usually not the transformer. It is compressed graphite fel...
