Heating by induction is a popular approach for heat treatment of metal components in modern industry. Conventional induction heaters that are widely used for through heating of billets be fore hot forming have high resistive losses in hollow water-cooled copper windings. In average, 40-50% of the total power is removed by the cooling water.Read full article
