【 摘 要 】

For the process that massive limestone is added into converter directly, the problem of slow slagging and low dephosphorization rate can generate. The transformation of converter oxygen lance has been considered in the paper, realizing the oxygen lance blowing powder of granular limestone slag and the rapid slagging and high efficiency of dephosphorization. Based on 120t converter smelting, the consumption of limestone in this process has been calculated in this paper, and a multi-function oxygen gun has been designed to provide guidance for actual production.
