Abstract
Способ получения ферритно-кальциевого комплексного материала, включающий обжиг железосодержащего материала в трубчатой вращающейся печи с использованием газообразного топлива, отличающийся тем, что в качестве железосодержающего материала используют шлам сталеплавильного производства, содержащий оксиды железа, кальция, магния, в котором содержание Feобщ. составляет не менее 48%, содержание SiO2 составляет от 0,5 до 3,5%, а содержание СаО и MgO удовлетворяет соотношению CaO/MgO=1,5-6,0, 1-2% свободного углерода в форме графита.A method of producing a ferrite-calcium complex material, comprising calcining an iron-containing material in a tubular rotary kiln using gaseous fuels, characterized in that steel-containing sludge containing iron, calcium, and magnesium oxides is used as the iron-containing material, in which the content of Fetotal. is not less than 48%, the content of SiO2 is from 0.5 to 3.5%, and the content of CaO and MgO satisfies the ratio CaO / MgO = 1.5-6.0, 1-2% of free carbon in the form of graphite.
