Another way to save energy is to use the residual heat in the continuous casting process. At this time, the bar is sent directly from the casting site to the reducer, and the surface quenching and heat loss through radiation cause a temperature gradient from the surface to the center. If induction heating is used at this stage without cooling it down, the required heating power can be much smaller.

For example, the power required to heat from ambient temperature to the blanking rolling temperature (15 minutes) is 100 MW, which can be reduced to 35 MW with 1 minute of reheating. In some cases, the size of the bar to be heated through requires a transverse heating system. For smaller bars, the conveying mechanism is simple, but larger bars can be handled by a step-by-step method. The efficiency of the smaller bars can greatly save energy compared to the sequential method. At 60 Hz, a 2 mm bar requires 30% less power, and at 1 kHz, a 38 mm bar requires 40% less power. At 3 kHz, a 25 mm bar requires 45% less power. The only way to get an accurate cost comparison is to perform an accurate analysis based on the specific requirements of the equipment being designed.
