Abstract

Способ металлизации окатышей железосодержащего сырья с получением гранулированного железа и шлака, включающий окомкование смеси железорудного концентрата, твердых углеродосодержащего и кальцийсодержащего материалов со связующим компонентом с получением железорудных окатышей, ввод железорудных окатышей в печь с вращающимся подом, их нагрев, охлаждение, дробление и отделение железных гранул от шлака, отличающийся тем, что в качестве железосодержащего сырья используют ванадийсодержащий титаномагнетитовый концентрат, в условиях металлизации окатышей в шлаке содержание FeO поддерживают в пределах 8-25%, массовое отношение оксида кальция к кремнезему (CaO/SiO2) - в пределах 1,25-4,0, а процесс металлизации окатышей завершают при температуре 1535-1540°С.A method for metallizing pellets of iron-containing raw materials to produce granular iron and slag, including pelletizing a mixture of iron ore concentrate, solid carbon-containing and calcium-containing materials with a binder component to obtain iron ore pellets, introducing iron ore pellets into a rotary hearth furnace, heating, cooling, crushing and separating iron granules from slag, characterized in that as an iron-containing raw material, a vanadium-containing titanomagnetite concentrate is used, under meta conditions For the pelletization in the slag, FeO content is maintained within the range of 8–25%, the mass ratio of calcium oxide to silica (CaO / SiO2) is in the range of 1.25–4.0, and the process of pellet metallization is completed at a temperature of 1535–1540 ° С.
