Power Focus TechnologyTM
This technology ensures individual power supply per heating zone, according to the necessary process-related temperature gradient. The top zone of a taper furnace always requires more power due to the higher top temperature, in contrast to the bottom zone of the block. This results in greatly differing degrees of utilization in the respective heating zones. Here, the Power Focus TechnologyTM takes into account the requirement to compare and also improve the energy utilization efficiency of the IGBT converter. This leads to a lower connected load, especially in the case of a so-called taper furnace, which is always linked to a preheating system.
The power supply is therefore utilized considerably and at the same time the peak load in the power supply is smoothed. In a typical application for a throughput of 4 - 5 t on an 8“ or 9" furnace line, a system with Power Focus TechnologyTM requires approximately 25% less connected load without any impact on the heating throughput in hybrid operation with a billet preheater. As a result, the energy distribution can also be made smaller, which in turn leads to lower basic losses and thus better resource utilization.
