| Abstract: | According to the ionic theory proceeding from the thermodynamic analysis of converter slag dephosphorization the final products in the gasification dephosphorization reaction have been calculated and determined, thus providing a theoretical basis for thermodynamic feasibility of gasification dephosphorization in the process of furnace protection by slag splashing. Results show that gasification dephosphorization in converter by slag reduction is feasible. Effects of such a few factors as temperature, basicity, FeO content and flowing nitrogen on the balance partial pressure are discussed. |
