Article Preview

For describing and resolving the process of chromium ore smelting reduction preferably, the coupling dynamic model was established using metallurgical thermodynamics, dynamics and reaction engineering. The different influencing factors were investigated and discussed. The results of the model show that the mass transfer of Cr2O3 in the slag phase is rate-determining step. The initial hot metal should contain definite chrome metal and the yield of chromium in slag should be controlled properly at 1560°C so as to decrease refining time considerably and improve production efficiency for producing stainless steel crude melts in a converter. A reference and basis for the constitution of rational processing route in a practical converter steelmaking have been afforded.
