The annealing furnace changes the crystal structure, refines the structure, eliminates stress and softens the material to the metal material and the workpiece, and vacuum annealing can prevent oxidative decarburization, degassing and degreasing, and evaporation of the oxide to improve the surface brightness and mechanical properties of the workpiece.
Mainly suitable for deep-drawn stainless steel parts, such as plumbing equipment, water expansion parts, pins, medical equipment, stainless steel nails, stainless steel stranded wire, riveted parts, stainless steel bearings, case, strap, tool, micro shaft, self-drilling, self-drilling A multi-purpose furnace for continuous bright annealing, solid solution, demagnetization and stainless steel quenching treatments, such as tableware under the control of a protective atmosphere. After treatment, the product has a smooth surface, no oxidation and no decarburization. It has the advantages of high production efficiency, low energy consumption, less pollution, convenient operation and low labor intensity. It can also be used for brazing and sintering of metal materials.
