ABSTRACT:
A control system and method for controlling the oxygen content in continuously cast metal. The control system includes means for sensing the oxygen content of the molten metal at a first point upstream from the casting mold, either means for measuring the rate molten metal enters the casting mold or means for supplying molten metal to the casting mold at a constant rate, oxygen addition means for adding oxygen to the molten metal before it enters the casting mold, and control means for controlling the oxygen addition means in response to both the rate metal is supplied to the casting mold and the oxygen level of the molten metal at the first point. In the method of the invention, oxygen is added to the molten metal intermediate the first point and the casting mold in response to the oxygen content of molten metal at the first point and the rate molten metal enters the casting mold.
