Abstract
A method of and apparatus for localized control of heat flux in continuous casting of thin cast strip comprising removing oxides from the casting surface of each casting roll by contacting the casting surface of each casting roll with the rotating brush in advance of the casting area, and delivering gas at the casting surface between the rotating brush and entry to the casting area to form a gas layer on the casting surface of each casting roll where the oxides have been removed. The delivering of gas at the casting surface between the rotating brush and entry to the casting area is preferably done in at least three zones along the casting roll axes to form a gas layer on the casting surface of each casting roll where the oxides have been removed, where the gas projected in the respective zones can be of different composition, mixture, pressure, or combination thereof.
