ABSTRACT:
A method is disclosed for the deoxidation of open type steels, e.g. rimmed and capped steels, which are particularly useful in the production of sheet products with improved formability. The requisite amount of deoxidation in the ladle is achieved through the use of conventional deoxidizers, other than aluminum (preferably silicon carbide). Deoxidation in the mold is also achieved without the use of aluminum. Here, however, it is necessary that mold deoxidation be achieved through the use of magnesium, generally added in the form of a magnesium-nickel alloy.
