The induction case annealing machine skeleton is welded by various types of steel, and the outer frame is made of channel steel as the main beam.
The induction case annealing machine usually uses pure hydrogen as an annealing atmosphere, and the atmosphere preferably has a purity of more than 99.99%. If the inert gas in the atmosphere, another part, can be obtained with a lower purity, but does not contain too much oxygen, water vapor.
The annealing furnace is a metal heat treatment process in which the workpiece is heated to a predetermined temperature and then slowly cooled after being kept for a certain period of time.
