    摘要： A twin drum-type continuous casting process for casting thin cast strip by solidifying molten steel continuously fed between a pair of cooling drums placed parallel to each other, wherein the cooling drums are given an added degree of concave crown such that a solid fraction at the thickness center of the thin cast strip, when the distance from the edges toward the center of the thin cast strip at the closest position of the cooling drums is within 50 mm, is exhibited which is a value greater than the fluid critical solid fraction, or alternatively the cooling rate near the edges of the cooling drums is improved.

    摘要： A cooling drum for a twin-drum continuous casting machine is capable of ensuring an excellent drum body interior cooling effect and advantageously overcoming both the problem of wear of the cooling drum end portions that are pressure-contacted with, and slide on, the side dams and the problem of their local deformation, and that, as a result, can ensure long-term maintenance of a suitable pressure-contact sliding state between the side dams and the cooling drum so as to enable stable continuous casting over a prolonged period. The cooling drum comprises a drum body portion of a material having a thermal conductivity of 100-400 W/mK and drum end portions part or all of whose portions in pressure-contact with the side dams and/or part or all of whose inner regions are formed of a reinforcing material that is a high-hardness material having a Vickers hardness HV (250 g) of 300-600.
