The steel-framed building derives most of its competitive advantage from the virtues of prefabricated components, which can be assembled speedily at site. Unlike concreting, which is usually a wet process conducted at site, steel is produced and subsequently fabricated within a controlled environment. This ensures high quality, manufacture offsite

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. ...

the crude steel before converting the liquid steel into a solid. (Steelmaking) The majority of the BOS process usually occurs in large steel processing plants known as steel mills (Steelmaking). This is necessary because steelmaking is a fast-paced process that cannot afford the lengthy transportation time from one plant to another.

Steel plants also use water for an array of miscellaneous applications to support plant operations, including water for general cleaning purposes, drinking, sanitary systems, and other needs. Many of these applications have less stringent water quality requirements than those required by cooling and process equipment employed in steel production.

Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being continually improved ...

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).
