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.

摘要： A method of and apparatus for continuous casting of thin cast strip including removing oxides from the casting surface of each casting roll by contacting the casting surface of each casting roll with a rotating brush between the nip and the casting area, determining the temperature in segments along the casting roll surfaces or across the cast strip adjacent the nip, and delivering gas adjacent the casting surface between the rotating cleaning brush and the casting area regulated in segments corresponding to the determined temperature in the segment to control the quality of the strip produced. The gas delivery adjacent the casting surface between the rotating brush and the casting area may be done in at least five segments along the casting roll, and the temperature determination step may be done in a continuum such as by a scanning pyrometer. The temperature determination of the cast strip may be done between 0.2 and 1 meter from the nip.

摘要： A method of casting steel strip by introducing molten plain carbon steel on casting surfaces at least one casting roll with the molten steel having a free nitrogen content below 120 ppm and a free hydrogen content below about 6.5 ppm measured at atmospheric pressure. The free nitrogen content maybe below about 100 ppm or below about 85 ppm. The free hydrogen content maybe between 1.0 and 6.5 ppm at atmospheric pressure. Novel cast strip of plain carbon steel is produced having a strip thickness less than 5 mm or less than 2 mm by use of the method.
