FIELD: metallurgy.
SUBSTANCE: method involves loading of scraps into a metallurgical unit, its melting and gas purging by means of an injection device. At the beginning of scrap melting, the injection device is operated in a burner mode, in which supply of natural gas and oxygen is performed to the injection device. Then, the injection device is changed over to an injector mode, in which supply to it of oxygen, natural gas and hot air is performed, and based on the above, a high-speed jet with a gaseous envelope fully enclosing it is performed.
EFFECT: enlarging functional capabilities of an injection device.
