Alloying elements and additional agents can be added either in the furnace or the ladle. During the steel production process, oxygen may become dissolved in the liquid metal. As the steel solidifies, the oxygen can combine with carbon to form carbon monoxide bubbles that are trapped in the steel and can act as initiation points for failure. Deoxidizing agents, such as aluminum, ferrosilicon and manganese, can eliminate the formation of the carbon monoxide bubbles.
Completely deoxidized steels are known as killed steels. Steels that are generally killed include:. Regardless of the refining process, the molten steel, with the desired chemical composition, is then either cast into ingots large blocks of steel or cast continuously into a desired shape. Continuous casting with hot rolling is becoming the standard production method, since it is more energy efficient than casting ingots, as the ingots must be reheated prior to shaping the steel into the final product.
Cold-formed steel is produced from sheets or coils of hot rolled steel which is formed into shape either through press-braking blanks sheared from sheets or coils, or more commonly, by rollforming the steel through a series of dies. No heat is required to form the shapes unlike hot-rolled steel , and thus the name cold-formed steel. Cold-formed steel members and other products are thinner, lighter, and easier to produce, and typically cost less than their hot-rolled counterparts.
