Abstract

In the work the possibility to synthesize cast ferrochrome alloys with different contents of chromium under the combustion mode is studied using aluminum as a reducer. Combustion laws in Cr2O3–Fe2O3–Al model system, microstructures of obtained phases are studied, composition and density of products are determined. Characteristic features of synthesizing ferrochromes, and main factors influencing on combustion laws, phase separation, density, microstructure and composition of products are revealed. It is established that composition and yield of ferrochrome ingot may be regulated by the ratio of iron and chromium oxides, quantity of reducer.
