04-04-2012· Originally, charcoal produced from wood was the fuel used to melt the iron ore. A tremendous amount of wood was needed for this industry. For example, one type of furnace, the Stuckofen, used in fourteenth century Germany could produce 4000 pounds of iron per day with a fuel rate of 250 pounds of charcoal per 100 pounds of iron produced ( Wakelin, 1999 ).
The Manufacture of Steel - NZ Institute of Chemistry
Iron ore is converted to steel via two main steps. The first involves the production of molten iron and the second is that of actual steel manufacture. The details of these steps are outlined below. Step 1 - The production of molten iron The Primary Concentrate is mixed with limestone and coal and heated. The iron oxides are
THE FUNDAMENTAL ASPECTS OF IRON ORE REDUCTION
T RON ore reduction is the conversion of iron oxide minerals to metallic iron. The chemical reactions involved take place in the blast furnace during the production of hot metal or in the several proposed solid-state processes that pro-duce sponge iron. Because there are three oxides of iron, hematite, magnetite and wustite, and be-
Reduction of Iron Oxides with Hydrogen—A Review,
Prior oxidation of magnetite ore to Fe 2 O 3 leads to similar reduction behavior when compared with natural hematite; however, natural magnetite is hardly reducible due to low porosity and the formation of dense intermediate products during the reduction. 8) Accompanying oxides in the iron ore, such as alumina, influence the reduction rate.
