摘要： The invention relates to metallurgy, in particular to smelting pig-iron in a blast furnace. The method for smelting pig-iron in a blast furnace comprises loading solid fuel, iron-ore materials and fusing agents into a blast furnace. The solid fuel used is coke which is produced by coking a charge comprising a product produced by retarded coking at a temperature of up to 500°C of a mixture of heavy sulphur residues from petroleum processing and a reagent - an alkaline earth metal oxide or an alkaline earth metal hydroxide. The quantity of reagent in the mixture is from 0.1 to 2% per percentage of sulphur content in the heavy sulphur residues from petroleum processing. The quantity of fusing agents is determined on the basis of ensuring a modulus of basicity of the slag of 0.29-0.77. The use of the invention provides for an effective reduction in the sulphur content in pig-iron and a reduction in fuel consumption.
