Steel making process. Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron ...

When this process step is over, the iron has turned to steel. The liquid steel is then cast into solid slabs or ingots and processed to long products like bars or wire or flat steel strip in several rolling operations. Other additional operations to enhance the characteristics and functions of steel include tempering or coating.
