发明名称 Method of improvement of the heat-balance in the refining of steel
摘要 In the method of producing steel in a converter equipped with tuyeres that are shrouded with a protective medium which are disposed below the melt surface, oxygen is also introduced above the melt during at least a major part of the refining time with sufficient velocity to suck in large amounts of reaction products thereby increasing the proportion of the scrap that may be charged.
