To address the problems occurring during semisteel smelting in converter in Pangang,such as slow slagging,low rate of dephosphorization,and high rate of rephosphorization after converter smelting,corresponding measures have been taken to optimize slagging process,oxygen supply,bottom argon supply,and end-point control.With these countermeasures,the dephosphorization rate has been significantly increased.The production practice shows that the average dephosphorization rate is above 90% with single-slag process.In addition,the final phosphorus content can be controlled below 0.007%,and the rephosphorization rate after converter smelting can be controlled below 0.003%,satisfying the requirement for [P] controlled below 0.010% for steel products.
