Induction forging

Typically metals are heated to between 1,100 and 1,200 °C (2,010 and 2,190 °F) to increase their malleability and aid flow in the forging die.

This can be done using the heat content of the material, which is normally expressed in KW hours per tonne, the weight of metal to be processed and the time cycle.

Traditionally this process involved lengthy and complex calculations in conjunction with a mixture of practical experience and empirical formula.

As the heat is predominantly generated in the surface of the component it is important to select a frequency which offers the deepest practical penetration depth into the material without running the risk of current cancellation.

A range of handling solutions including conveyors, in line feeders, pusher systems and walking beam feeders are utilised to facilitate the heating of multiple components whilst delivering single components to the operator at the required time cycle.

This process utilises similar systems to bar end heating except that the whole of the billet is driven into individual coils.
