Sažetak
The carried out high-temperature experiments with use of a three-level lance on a laboratory facility which includes a 60-kg converter with magnesia lining allowed defining the main technological parameters. They include the peculiarities of the blowing regime (periodic change of the oxygen of the additional nozzles on a neutral gas) in order to avoid excessive overheating and overoxidation of the slagmetal emulsion, that adversely affect the life of BOF lining. At the same time, it is possible to provide the supply of oxygen through the upper nozzle block of the lance with the formation of postcombustion torches that spade only within the near-lance zone of CO release to the bath surface.
