Stainless steel medium-frequency induction heating and pushing elbow forming process

The invention discloses a stainless steel medium-frequency induction heating and pushing elbow forming process which adopts a medium-frequency induction heating and pushing technology, the diameter of a selected material is 0.63-0.77 times of the diameter of an elbow, the diameter of the selected material is reduced, the price is lower when the diameter of the material is smaller, the material consumption is reduced, and the manufacturing cost is saved. The induction heating coil adopts the structure that the caliber is increased from the small caliber to the large caliber along with the core rod, the winding density is large, the gap between the induction heating coil and the pipe blank is small, the heating speed is increased by adjusting the structure of the induction heating coil, the heating temperature is increased, the induction heating coil is covered with refractory fiber cotton, heat loss is reduced, the heating temperature is better, and the service life is prolonged.
