METHOD OF BLAST FURNACE OPERATION REGULATION Russian patent published in 1994 - IPC

Abstract RU 2017826 C1

FIELD: nonferrous metallurgy. SUBSTANCE: during estimation of carbon amount, fed in blast furnace, mass of conditional carbon, changed by fuel addition is additionally taken into consideration, actual ratio of iron/carbon is determined and it is compared with given value, which is set in limits of 1.6 - 2.3 kg/kg. Mathematic calculations of carbon amounts are given for cases, in which reduction gass, solid or liquid fuel are used as fuel additions. EFFECT: method allows to decrease level of temperature range of cast iron, shares of silicon and sulfur in it and special consumption of coke. 3 cl
