Research and Application of New Oxygen Lance for BOF Steelmaking

Abstract:

This paper compares the structure and basic points of the new lance with traditional ones, analyses the new design with center hole in head in fields of theoretical supersonic jet characteristics including penetrating depth and stirring energy, operation mode in smelting process and. The application results show its advantages in keeping whole dephosphorizing rate, final carbon-oxygen equilibrium control of steel and cost reducing, on the other hand, point to its several drawbacks. Optimize solutions are introduced at the end.
