The invention provides a secondary cooling method and device for a continuous casting machine. The method comprises the following steps of: arranging a plurality of secondary cooling subareas in a casting direction, wherein each secondary cooling subarea comprises at least one cooling unit; arranging a plurality of spraying collector tube outlets in a spraying collector tube, wherein each sprayingcollector tube outlet is connected with a corresponding spray nozzle pipeline and a corresponding spray nozzle; introducing a cooling medium into the spraying collector tube through spraying collector tube inlets, and spraying and impacting the cooling medium to the surface of cast blank to perform secondary cooling through the multiple spray nozzles; and independently controlling each secondarycooling subarea by regulating pressure and flow of the cooling medium. According to the secondary cooling method provided by the invention, outflow amount of single spray nozzle can be controlled andregulated, so that secondary spraying water amount inside single subarea is close to linear changes, smooth transition of secondary cooling water amount between every two adjacent subareas is guaranteed, cooling uniformity of the secondary cooling subareas is improved, stress concentration of cast blank and crack generating probability are reduced, cost increase is hardly generated, and operability is strong, and therefore, the secondary cooling method has a very wide market and a very wide application prospect.

The invention discloses a single-stand reversible rolling process for an ultrathin wide red copper belt, particularly relates to the technical field of reversible rolling of red copper belts. The technical scheme is that the single-stand reversible rolling process comprises the following specific steps that S1, a copper raw material is put into an intermediate frequency furnace for smelting until a liquid state is reached; S2, the obtained smelting liquid forms a casting blank with a certain section shape and a certain size specification through a continuous casting machine, and the casting blank is cooled through water till the temperature of the casting blank is reduced to 20-30 DEG C; S3, the casting blank is put into a forging press to be forged and pressed, and a red copper plate material is obtained; and S4, the red copper plate material is put into water, and the red copper plate material is cleaned. The single-stand reversible rolling process has the beneficial effects that the red copper plate material is rolled for four times through a rolling mill, then the red copper belt is reversibly rolled through a reversible rolling mill, therefore the thickness of the red copper belt can be reduced, the use range of the red copper belt can be widened, and the tensile strength and smoothness of the red copper belt can be improved.
