The billet secondary heating furnace adopts intermediate frequency series resonance power supply to control its characteristics:

● Parallel resonance design, phase shifting and power adjustment, the equipment is mature and stable; it has more advantages in the high power range above 3000KW.

● DSP control, fast capture phase lock start, meet frequent start and stop, high success rate.

● Frequency conversion and variable load adaptation, frequency adaptation range 200-10000Hz, automatic matching for induction furnace replacement, without any manual adjustment.

● T2 red copper copper bars are used in the cabinet, which are sandblasted and passivated; low leakage inductance, anti-oxidation, effectively reducing line loss.

● Full touch screen control, pure digital setting, complete process record and strict level authority. The main parameters can be restored to factory settings with one key.

● The power of a single power supply is 50-6000KW, and the frequency is 200-10000Hz.

The induction heating coil of the steel billet secondary heating furnace is a profiling design. The copper tube is wound with T2 oxygen-free copper. The wall thickness of the copper tube is ≥2.5mm. The furnace body insulation material is made of knotted materials imported from the United States. It has high strength, high temperature resistance and long service life. Longer; the inlet and outlet ends of the furnace body of the steel billet secondary heating equipment are encapsulated with 5mm copper plates to reduce magnetic flux leakage and prolong the service life. The furnace body chassis frame is made of non-magnetic stainless steel or aluminum alloy to reduce the influence of magnetic leakage and heat generation on other devices. A water-cooled roller is installed between every two furnace bodies, and each roller is equipped with a variable-frequency speed-regulating motor to ensure the stable and uniform speed of the billet.
