Embodiment

[0010] The surface treatment method of the casting roll is carried out through the following steps:

[0011] S1: A concavo-convex pattern forming operation to form a concavo-convex pattern on the surface of a casting roll; and an electropolishing operation by electrolytic polishing to round a plurality of convex portions and a plurality of concave portions of the concavo-convex pattern formed in the concavo-convex pattern forming operation shape.

[0012] S2: In the concavo-convex pattern forming operation, the surface of the casting roll can be surface-treated using a shot peening method.

[0013] S3: In the shot peening method for the concave-convex pattern forming operation, when the casting roll is surface treated, shot peening balls with a diameter of at least 3.5 mm may be projected.

[0014] An advantage of the present invention is that it is possible to improve the shape of the convex portion that determines the surface roughness of the surface treatment portion to pr...

Abstract

The invention relates to a surface treatment method for a casting roller. The surface treatment method comprises the steps: carrying out concave-convex pattern forming operation for forming a concave-convex pattern on the surface of the casting roller; carrying out electrolytic polishing operation for electrolytic polishing; and treating a plurality of convex parts and a plurality of concave parts of the concave-convex pattern formed in the concave-convex pattern forming operation to form a round.

Description

technical field [0001] The invention relates to a method for surface treatment of a casting roll used in a twin-roll sheet casting process. Background technique [0002] Generally, the casting process is the process of solidifying molten metal to produce a slab of uniform thickness. Recently, a thin plate casting technique has been developed and used, in which molten metal is directly solidified into a thin plate having a thickness close to the final product by using two casting rolls, but the roughness of the casting roll surface is an urgent problem to be dealt with. Contents of the invention [0003] The surface treatment method of a casting roll provided by the invention can solve the above problems. [0004] A method for surface treatment of casting rolls provided by the present invention includes: a concave-convex pattern forming operation for forming concave-convex patterns on the surface of the casting roll; The plurality of convex portions and the plurality of c...
