Abstract
Способ переработки ванадийсодержащих титаномагнетитов при прямом легировании стали ванадием, включающий восстановление рудных материалов углем или углесодержащими материалами в агрегате прямого жидкофазного восстановления с одновременным получением чугуна и горячих восстановительных газов, подачу горячих восстановительных газов в агрегат металлизации, плавку в дуговой электропечи с использованием жидкого чугуна, металлизированных окатышей и лома, отличающийся тем, что часть горячих металлизированных окатышей из агрегата металлизации загружают в агрегат прямого жидкофазного восстановления, при этом доля металлизированных окатышей в шихте агрегата прямого жидкофазного восстановления m определяют из соотношения ! , ! где FeOж.к и FeOм.o - содержание FeO в железорудном концентрате или другом железорудосодержащем материале (в пересчете на оксидов железа на FeO по кислороду) и в металлизированных окатышах, соответственно. A method for processing vanadium-containing titanomagnetites with direct alloying of steel with vanadium, including the reduction of ore materials with coal or carbon-containing materials in a direct liquid-phase reduction unit with simultaneous production of cast iron and hot reducing gases, supply of hot reducing gases to a metallization unit, melting in an electric arc furnace using liquid iron, metallized pellets and scrap, characterized in that part of the hot metallized pellets from the metallization unit are loaded into the direct liquid-phase reduction unit, while the proportion of metallized pellets in the charge of the direct liquid-phase reduction unit m is determined from the ratio! ,! where FeOzh.k and FeOm.o - the content of FeO in iron ore concentrate or other iron ore-containing material (in terms of iron oxides to FeO in oxygen) and in metallized pellets, respectively.
