Annealing of steel pipe welds can normalize the coarse and uneven grains of the welds into fine ones.
Local annealing of cold heading workpieces can restore the elongated grains after cold heading to fine and uniform ones, to avoid damage to the corresponding part of the workpieces due to the degradation of mechanical properties during use.
Local annealing of carburized parts, such as the threaded part, is mainly to reduce the hardness of the corresponding part.
FOCO induction annealing machine
When the induction heating machine of FOCO induction is used for induction annealing, the power of the machine can be adjusted according to the process needs of the annealing workpiece. Induction annealing equipment can be equipped with infrared temperature detectors, automated loading and unloading systems.
