Steel - Steel - Primary steelmaking: In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures. Indeed, many of the reactions interfere with one another

Basic Oxygen Steelmaking Furnaces. The oxygen burns out the carbon as carbon monoxide CO and carbon dioxide CO2 gas which is collected in the chimney stack and cleaned of its dust (Fe203, and lime particles, etc.). The elements Mn, Si and P are oxidized and combine with lime (CaO) and FeO formed by the oxidation of Fe to form a molten slag.
