Research Progress on Injection Technology in Converter Steelmaking Process

During the converter steelmaking process, gas-slag-metal three-phase emulsification is realized by injecting gas to complete metallurgical tasks such as slagging, dephosphorization, decarburization, and heating. As green intelligent development of steel industry progresses, injection technology also constantly innovating. In this review, types applications top blowing elements, bottom medium are reviewed. Three different combined processes compared. At same time, advantages disadvantages elements media respectively discussed. Finally, based on research application status technology, direction Accelerating innovation especially improvement breakthrough high efficiency, reductions environmental burden, long life will play an important role in promoting transformation industry.
