Overview Highlights The basic steel products industry is involved in manufacturing hot metal, pig iron, and silvery pig iron from iron ore and iron and steel scrap. It also converts pig iron, scrap iron, and scrap steel into steel, and hot rolls iron and steel into basic shapes such as plates, sheets, strips, rods, bars, and tubing.

Integrated steel plants utilize mostly five materials such as raw materials, air, water, fuel and power to produce steel. During the production of steel, 2–4 t of wastes are being generated per tonne of steel produced.The various solid wastes in the form of slags and sludges that are emerged from steel plants are blast furnace slag, blast furnace flue dust and sludge, …

How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...
