Abstract Scope |
In order to realize the gasification dephosphorization process in converter slag splashing stage for avoiding the P enrichment, and the dephosphorized slag can be left for recycling in subsequent furnaces. The migration behavior of P during the slag gasification dephosphorization was studied. The results show that P element in converter slag is mainly enriched in silicate phase. The FeO in the converter slag is reduced by the coke into a large-diameter granular elemental Fe phase. The P2O5 in the slag is reduced by the coke at high temperature as P2 steam. Most of the P2 steam passes through the gas-slag interface and enters the furnace gas. A small part of the P2 steam will be adsorbed by the nearby elemental Fe phase to form iron phosphide. |
