Heavy bolts can be used in construction, bridge, marine, machinery manufacturing and other industries. Its production requires a lot of processes. Induction forging heat treatment by induction heating machine is required before it is formed.
The heating coil of induction heating machine can be customized, so several pieces are heated at the same time to improve heating efficiency. The heating speed of steel bars is fast and heating rapidly reduces oxide skin on bars. uniform heating temperature is good for mold of press machine.
In the continuous heating process, the load inside the induction coil is stable, thus to overcome the great heating power change caused by the great change of the load during the heating course from cool rod to 1100 degree rod. Its IGBT inversion technology and LC series circuit design achieves energy saving up to 15%-30% compared with SCR technology forging furnace.
