Thermodynamics Analysis of Hot Metal Dephosphorization Flux Reaction Process

Abstract:

In this paper, CaO-Fe₂O₃-CaCl₂ and CaO-Fe₃O₄-CaCl₂ system dephosphorizer depho- -sphorization of the thermodynamics of the use of FactSage thermodynamic calculation software Equilib module of hot metal dephosphorization flux and the balance between the response calculated, to find the right dephosphorizer dephosphorization ratio and the conditions for optimal phosphorus removal. First of all, by the beginning of slag and the final calculated optical basicity slag and phosphate capacity, calculated on the balance FactSage software phosphorus content mapping, and comparative analysis. Followed by software at different temperatures to calculate the iron liquid, liquid slag, slag liquid solid phase of calcium phosphate and calcium phosphate and quality data on the thermodynamic equilibrium temperature mapping analysis..
