Abstract
The present invention relates to a process for improving energy supply when heating and melting a scrap bulk wherein a preheated oxidizing gas with addition of fossil fuels melts a channel into the scrap bulk and further energy supply occurs through this channel. A significant improvement of the process is achieved by supplying hot blast to the scrap bulk from the top.
