Altering the microstructure in order to improve tensile properties of bow shackles resulted inconsistency fatigue performance. This raises question whether life can be attributed microstructural changes along profile shackle or decarburization at surface. Bow forged from 080M40 (EN8) material were subjected different heat treatments alter microstructure. The five load cases, which represented t...

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 ar...
