Sažetak

In the article presented the refined ferrochrome smelting technologies by furnace, converter and out-of-furnace methods. The main attention is paid to the new aluminum-silicothermal process for obtaining refined ferrochrome by the furnace method using a multicomponent alloy - aluminosilicochrome. The results of laboratory experiments on the smelting of ferrochrome using the multicomponent alloy are presented. As a result, melting products were obtained: ferrochrome with 63 – 68 % chromium and 1 – 3 % carbon and slag with 2 – 6 % chromium oxide.
