Iron and Steel Industries
Quick Review

➢ Iron and steel is the mother of all industries and forms the backbone of industrial development.
➢ It provides raw material to industries for manufacturing industrial machinery, railway engines, railway tracks, electrical machinery, defence equipments, bridges, dams, shops, automobiles, etc.
➢ India has one of the richest reserves of all the raw materials required for the industry, namely, capital, cheap labour, iron ore, power, coal, etc.
➢ Indi is the fifth largest crude steel producing country in the world.
➢ The main raw materials required for iron and steel is iron ore, manganese, limestone, silica, chromate, feldspar, scrap iron, flux and fuel.
➢ To make steel, impurities in the iron ore like, sulphur, silica, phosphorous, lime, etc. needs to be removed. It is done through the following process-
(a) During the iron making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes such as limestone.
(b) This slag floats on the molten iron and is collected at the base of the furnace at regular intervals.
(c) The product obtained is known as pig iron which can be converted into wrought iron, steel and cast iron.
(d) Through deoxidation the impurities are removed to convert pig iron into steel.
(e) The steel is cast into ingots and rolled into different sizes.
