Steel manufacturing

Steel manufacturing

1. Take iron coke and limestone and put it in a blast furnace

   • Remove impurities from the molten iron like carbon and sillicon
     • Add elements for steels composition and its purpose.
       • Steel making by BOS or Electric arc furnace
         • Secondary steel making process to improve consistency, temperature and composition
           • Continous casting for solidification where the steel is cut into billets, blooms and slabs
             • HR: The pieces are put into a furnace until they reach a certain temperature for rolling. They pass through mill stands and at the end they are cooled in an appropiate way
             • CR: Thiner, better forming properties and surface finish, protection from corrosion and decorative purposes.
             • Tube: flat steel strip or plate and form it into a cylinder by rolling or pressing
