Abstract
In a blast furnace process for producing iron gaseous hydrocarbons are introduced at the tuy<\>geres and the amount of coke normally charged is reduced, the amount of reduction per ton of hot metal produced being between 0.8 and 1.0 moles of contained carbon per mole of carbon in the hydrocarbon plus 0.2-0.4 moles of contained carbon per mole of hydrogen in the hydrocarbon. The blast temperature is raised above normal by 30-60 DEG F. for each mole of carbon by which the coke addition is decreased, and the amount of coke per ton of hot metal is further reduced by 1.66-4.16 moles of contained carbon per 100 DEG F. increase in blast temperature. The blast may be enriched with oxygen, the addition being about 1/2 mole of high purity oxygen per mole of carbon in the added hydrocarbon.
