Pharmacology

Iron is an element with atomic symbol Fe, atomic number 26, and atomic weight 55.85.

How it is made

The blast furnace is the predominant method for making iron. In essence, the blast furnace is a large, countercurrent, chemical reactor in the form of a vertical shaft which is circular in cross section. Iron ore, coke, and fluxes constitute the burden which is charged continually into the top. Pressures in the shaft are controlled to 100-300 kPa (1-3 atms) gauge. Preheated air (hot blast) is blown in through water-cooled nozzles (tuyeres) around the circumference of the furnace near the bottom.

The oxygen in the air reacts with the coke to form hot reducing gases (mostly carbon monoxide) which ascend through the burden and (1) provide heat for melting, (2) react with the iron ore to reduce it to iron, and (3) heat the ore, coke, and fluxes to reaction temperatures. Nitrogen in the hot blast is heated by the coke combustion, and aids in heat transfer to the burden. The gases leaving the top of the furnace (top gases) are cleaned, cooled, and used as fuel to preheat the air for the hot blast. Molten iron (hot metal or pig iron) and slag (molten oxides) are produced and accumulate in the bottom of the furnace.

Direct smelting processes use coal directly instead of coke. Several processes are under development which effectively divide the functions of the blast furnace into two separate but connected unit operations. First, the iron ore is prereduced in a shaft furnace or a fluidized bed, depending on the process and the type of ore used.
