                                                                                    Forging induction heating

Induction hot forging and forming  is a process to heat metal material to 1000—1250 C degree in general. Induction forging furnace widely used in metal and foundry sector. The forging heating material are aluminum, carbon steel, brass ,copper, different material heat to different temperature.

DUOLIN induction forging separated into two types: Full forging and Partial forging.

Full forging is carried out in the induction furnace. Continuous feed relies on feeding system which pushes the billets through the heating tunnel coils. After hot forging, using localized compressive forces to shaping the billets.

Partial forging is heating the end of a bar to allow the material to be upset into a head, i.e. a bolt. The cold raw material can be heated one piece at a time or on a continuous feed basis.

Advantage:

1:max carbon steel production is 3 T/hour

2:diameter above 140mm or length above 400 mm workpiece need to make special heating furnace

3:heat uniform, tempreture  moniter,

4:heat rapidly, less oxide layer
