PULVERISED COAL FUEL FOR BLAST-FURNACE SMELTING

摘要

FIELD: chemistry.SUBSTANCE: invention relates to pulverised coal fuel for blast-furnace smelting from carbon-containing finely ground starting material which is a product with output of volatile substances of up to 25% in amount of (3-100) wt %, obtained via slow semicoking of black oil; the fuel contains a desulphurising agent, wherein the carbon-containing finely ground starting material and desulphurising agent are in the following ratio: carbon-containing finely ground material - (90-99) wt %; desulphurising agent - (10-1) wt %.EFFECT: using pulverised fuel in the energy field and ferrous metallurgy, specifically in the process of blast-furnace production of cast iron, increases efficiency of the blast-furnace process and improves environmental friendliness of the blast-furnace process, widens the raw material base used the pulverised fuel associated with the blast-furnace process.3 cl, 1 dwg, 2 ex, 3 tbl
