Cold Rolling Composite Technology: An Efficient, Eco-friendly Method for Metal Composites.

Cold-rolled composite is a composite technology that realizes metallurgical bonding between two or more metal materials with different compositions at normal temperature by using larger rolling pressure. In this paper, the flow and technical advantages of cold rolling composite technology will be discussed.

Cold rolling composite process flow

    1

(1) Cladding: Performing ultra-high strength and large reduction rolling on the combined strips.

(2) Annealing: Subjecting the composite plate to heat treatments such as diffusion annealing.

(3) Precision Rolling: Improving the plate shape and surface quality through leveling or tension leveling to meet supply requirements.

(4) Cleaning: Removing residues from the surface of the composite material.

(5) Temper Rolling: Repairing the material surface and performing other finishing operations.

(6) Slitting: Slitting the material according to customer requirements.
