Method for improving energy input in heating and melting of a scrap bulk, comprising the steps of:
- burning a channel into a scrap bulk with a hot, oxygen-containing gas jet having a temperature of at least 500.degree. C.;
- wherein the hot oxygen-containing gas jet is supplied in first and second phases, the second phase having a jet speed which is distinct and substantially higher than the jet speed of the first phase;
- and
- inputting additional energy for the heating and melting of the scrap bulk through this channel.
