Abstract
Способ ведения доменной плавки, включающий загрузку в доменную печь железорудных материалов, шлакообразующего компонента и твердого топлива, отличающийся тем, что в качестве шлакообразующего компонента используют ожелезненную известь, в которой Fe общ. 1-15%; SiO2 1,0-7,0%; CaO 83,0-93,0%; Fe2O3 1,43-21,43%; MgO 1-7%; Аl2O3 0,5-1,5%; с долей п.м.п.п. (потери массы при прокаливании) до 2,5%. A method for blast-furnace smelting, comprising loading iron ore materials, a slag-forming component and solid fuel into a blast furnace, characterized in that ironized lime is used as the slag-forming component, in which Fe total. 1-15%; SiO2 1.0-7.0%; CaO 83.0-93.0%; Fe2O3 1.43-21.43%; MgO 1-7%; Al2O3 0.5-1.5%; with a share of m.p.p.p. (mass loss on ignition) up to 2.5%.
