Claims (1)

Способ регенерации металлического хрома из содержащих окись хрома шлаков, образующихся во время конвертерных процессов, таких, как AOD, MRP, AOD-L, MRP-L, CLU, ASM, Conarc-Stainless steel, или вакуумных процессов, таких, как VOD, SS-VOD, RH, RH с применением кислородного копья, отличающийся тем, что шлак, образующийся в конце процесса продувки или обработки в конвертере или вакуумной установке, сливают и отводят в невосстановленном виде, этот шлак подают в электропечь, которую в остальном загружают обычной садкой, состоящей из металлолома и при необходимости остаточной пыли, дополнительно подают углерод и при необходимости кремний и во время плавки содержащуюся в введенном шлаке окись хрома восстанавливают с помощью углерода и кремния непосредственно в металлический хром.A method for recovering metallic chromium from chromium oxide containing slags generated during converter processes, such as AOD, MRP, AOD-L, MRP-L, CLU, ASM, Conarc-Stainless steel, or vacuum processes, such as VOD, SS -VOD, RH, RH using an oxygen spear, characterized in that the slag formed at the end of the purge or treatment process in a converter or vacuum unit is poured and removed in an unrepaired form, this slag is fed into an electric furnace, which is otherwise charged with a conventional charge, consisting of scrap metal and, if necessary, residual whether further fed carbon and silicon and, if necessary during smelting slag contained in the entered chromium oxide is reduced with carbon and the silicon directly to metallic chromium.
