Abstract

A method of reducing iron ore in a blast furnace comprises forming a charge of which at least 40% by weight of the iron ore is crushed, screened and/or agglomerated and of a size greater than 1/4 inch, the balance being iron ore, coke and limestone, introducing an air blast at a temperature of at least 1650 DEG F. and introducing a hydrocarbon gas at or near the level of the zone of highest temperature in the furnace. The hydrocarbon gas, e.g. natural gas, coke oven gas, or petroleum gases, may be cold or preheated to a temperature less than the air blast, the temperature in the furnace being controlled by varying the amount of hydrocarbon gas added. The ore may be dried to a moisture content of not more than 2% free moisture. It is stated that process shows a considerable saving in the amount of coke required compared to normal blast furnace practice.
