Steel Production
What is Steel?
Steel is an iron (Fe) Carbon (C) alloy. The carbon content is generally in 0.1 - 2.1% range. The amount of carbon in steel plays an active role in the classification of steel. Apart from carbon, there are alloying elements and impurities (which create impure pollution) in different proportions. It is the chemical composition of the elements the steel contains and the internal structure of the steel that gives the steel different properties. Alloying elements can be added to the steel at different rates, and the internal structure is controlled by heat treatments such as improvement, normalization, and etc., and steel with different properties is obtained according to the purpose of use. Manganese (Mn), Phosphorus (P), Sulfur (S) and Silicon (Si) are elements originating from the raw material during production and are found in certain proportions within the steel. Other elements (Cr, Ni and etc.) are added to the steel structure in desired amounts in the form of ferro-alloys.Modern steel production can be divided into six stages;
1. Iron Production
2. Primary Steel Production
3. Secondary Steel Production
4. Continuous Casting
5. Primary Shaping
6. Production, Fabrication and Finishing
