Abstract
Способ доменной плавки, включающий введение в шихту окатышей, агломерата, кокса, металлодобавок, флюса и коксозаменителей, отличающийся тем, что в состав шихты дополнительно введен электросталеплавильный шлак окислительного периода фракции 10-80 мм с содержанием 25-44% FeO, 5-23% корольков железа и основностью 1,8-3,6 и шунгит фракции 10-80 мм с содержанием углерода не менее 25% при следующем соотношении материалов, мас.%:при этом отношение CaO/SiOшихты поддерживают 0,80-1,10.A blast-furnace melting method, including the introduction of pellets, agglomerate, coke, metal additives, flux and coke substitutes into the charge, characterized in that the composition of the charge is additionally introduced with an electric furnace smelting slag of the oxidizing period of a fraction of 10-80 mm with a content of 25-44% FeO, 5-23% kings of iron and a basicity of 1.8-3.6 and shungite fractions of 10-80 mm with a carbon content of at least 25% with the following ratio of materials, wt.%: while the ratio of CaO / SiO charge support 0.80-1.10.
