Australian Steel Institute
Steelmaking begins when iron ore is smelted to produce metallic iron, which is then converted to steel by removing excess carbon and adding various alloys in a Basic Oxygen Furnace. It is then continuously cast and rolled into a variety of shapes and sizes. Hot rolled steel is produced for various uses; e.g. welded beams, reinforcing bar and floor plate
