The rolling component comprises a plurality of solid roller shafts 2, and the roller shafts 2 are arranged in the oven 1 in pairs up and down. The length of the roll shaft 2 is 1 m-2 m, and the roll shaft is made of high-strength alloy steel and has high strength, rigidity, wear resistance and hardenability. The roll shaft has higher processing precision, such as roundness, cylindricity, radial run-out and the like, the smooth finish of the outer surface is high, and the surface smoothness of the produced composite metal plate can be ensured.
