Research on the Thermodynamics and Kinetics of Chromium Ore Smelting Reduction Process for Producing Stainless Steel

Abstract:

For describing and resolving the process of chromium ore smelting reduction preferably, the research status on the thermodynamics and kinetics of chromium ore smelting reduction process was summarized, based on the introduction of the process for smelting stainless steel with hot metal in a converter. The existing problems for smelting stainless steel by chromium ore smelting reduction in a converter were also discussed and some suggestions were made for the future work. A lot of investigations about the thermodynamics and the reduction mechanisms of chromium ore have been done. However, the consistent view about the thermodynamic feasibility and the mechanism of smelting reduction has not been achieved, so the application of research results is limited. Little work about the reaction kinetic model for the production of stainless steel by chromium ore smelting reduction and direct alloying has been done. So the synthetic kinetic model including a dissolution model and a reduction model of chromium ore should be built to predict and control accurately the process.
