FIELD: metallurgy.
SUBSTANCE: method includes the bulk charge melting by fuel burning under conditions of the distributed burning due to flame deviation towards the bulk charge as continuation of the melting phase by means of the acting oxidant jet re-directing the flame in direction from the bulk charge, and by stepped change of distribution of the oxidant injection between the primary and secondary portions as continuation of distributed burning phase. Also burner is described.
EFFECT: more optimal melting of the bulk charge followed by fuel burning under conditions of the distributed burning.
