ABSTRACT:
An apparatus and method for casting metal strip includes a moveable chill body having a quench surface thereon. A nozzle mechanism deposits a stream of molten metal onto a quenching region of the quench surface to form the strip, and a gas supply mechanism provides an initial gas mixture, which consists essentially of carbon monoxide and oxygen. An ignition mechanism ignites the initial gas mixture to create an exothermic reaction which provides a low density, reducing flame atmosphere at a depletion region located substantially adjacent to and upstream from the quenching region. A control mechanism controls the initial gas mixture to produce an adjusted reducing flame atmosphere at the depletion region in which the adjusted reducing flame has a burnt gas composition that includes substantially no free oxygen.
