Abstract

Винахід стосується способу поліпшення ступеня відновлення металевих компонентів у збагаченому хроміту під час виплавляння феросплавів, придатних для виготовлення нержавіючої сталі. Збагачений хроміт подають разом з нікельвмісною сировиною так, що завдяки кількості нікельвмісної сировини досягають необхідного ступеня відновлення металевих компонентів феросплавів.
