What is the heating efficiency of the bar induction heating furnace?

Generally speaking, the thermal efficiency ratio of the bar induction heating furnace system is generally between 0.35--0.6, which is more efficient for steel pipe heating. The thermal efficiency ratio of the induction heating system of the bar induction heating furnace of the Haishan electric furnace is 0.68-0.72. This means that with the same power, the heating efficiency of the Haishan electric furnace intermediate frequency induction heating system can be increased by 5%-10%.

The power factor of the series resonance bar induction heating furnace is always greater than 0.95 or even as high as 0.99. The whole heating process can ensure that the rectification is fully open and achieve high power factor output. In this way, the high power factor output of the bar induction heating furnace represents the high utilization of transformer electric energy, which means that every kWh of electricity purchased by the bar induction heating furnace has a high utilization value.
