摘要： A method of controlling heat flux between the casting pool and the surfaces of the casting roll in a strip steel casting process includes controlling the concentration of nitrogen in the steel melt. The concentration of nitrogen may be controlled to achieve an operational heat transfer to the casting roll. The beat flux to the casting rolls may be controlled by maintaining the sum of partial pressures calculated from the nitrogen and hydrogen concentrations in the casting pool below 1.15 atmospheres. Decreasing the concentration of nitrogen can increase heat flux at the casting rolls.

摘要： 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.
