In this work, the effect of slag phase on dephosphorization in BOF (basic oxygen furnace) is explored by industrial practical experiments. The research results show that final rate related to rather than basicity and T.Fe content slag. correlation between ability proportion liquid (phase B) phosphorus-containing solid solution A) much higher RO (MgO·FeO, MnO·FeO) C). phosphorous partition fitti...

In order to make better use of converter dust achieve effective pre-dephosphorization molten iron, the influence addition ratio dedusting ash and oxide scale on dephosphorization iron was compared, so as reveal reasons for decrease rate caused by dust. Through theoretical analysis, XRD, SEM-EDS, Raman infrared spectroscopy, mineral phase structure, polymerization degree phosphorus structure fin...

A kinetic model was developed to study the dephosphorization of 600 MPa steel droplets under electromagnetic levitation conditions. The relationships which were derived from between and influence temperature gas flow rate in good agreement with experimental data. Both conducive evaporation phosphorus, effect having a greater than that velocity. results show rate-controlling step for process dif...
