| description | Based on the analysis of the advantages and shortcomings of the oxygen-converter production in Ukraine with combined oxygen and neutral gas blowing, a new combined-blowing technology by a threelevel lance has been proposed, which privedes the prolongation of the converter lining stability and a more efficient post-combustion of the exhaust gases with the prevention of local wear of the lining and intensive scraping of the lance body and the unit mouth. During the laboratory-industrial working-out of the proposed technology it was established that, depending on the level of the slag-metallic emulsion, two main post-combustion modes can be distinguished. The post-combustion process must be organized in such a way that the torches are within a half-diameter area of the outlet CO stream that prevents the torch's effect on the converter lining. |
