Problems solved by technology

[0005] Due to the uneven shrinkage around the rectangular row during drawing and extrusion, the solid-phase combination is poor, which affects the mechanical properties;
[0006] Copper layer coverage is uneven, which affects the conductivity;
[0007] Low yield, low production efficiency, high cost, etc.

Embodiment Construction

[0035] Taking the small-sized aluminum row blank (below 60*8 mm) as an example, the process flow is as follows figure 1 and shown in Figure 2. First use the coil, before the first coil 1 is used up, the head end of the coil 2 is welded or squeezed to the end of the coil 1, the time required is 3-4min, and the running speed of the whole line is decelerated at this time to 1-2m / min, after the welding is completed, the running speed of the whole line will return to 8-9m / min.

[0036] The docking method of the copper strip is the same as that of the aluminum row. Before the coil 1 of the copper strip is finished, the head end of the copper coil 2 is connected with the end of the copper coil 1 by argon arc welding or extrusion, and the whole line runs The center line is at a height of 1.2m, and the copper skin elevation is below the operating center line. The centerline of the copper skin and the centerline of the aluminum row are in a vertical plane.

[0037] In the role of pin...

Abstract

The invention relates to a continuous metallurgical composite production process for copper-clad aluminum rows. The process comprises a pretreatment step, a continuous coating step, a welding step, acontinuous rolling step, an on-line automatic monitoring step and a diffusion heat treatment step, thereby achieving the following technical effects of: (1) ensuring full uniform combination of coppersheets and aluminum rows, as well as uniform thickness of copper coating; and (2) greatly improving finished-product rate and ensuring yield and quality. Therefore, the production process solves theproblem of producing the copper-clad aluminum rows with various specifications, is particularly applicable to the manufacture of large-size copper-clad aluminum rows, and has huge economic benefit.

Description

technical field [0001] The invention relates to a production process of a copper-clad aluminum bar, in particular to a production process of continuous metallurgical compounding of a copper-clad aluminum bar. Background technique [0002] Copper-clad aluminum refers to a composite conductor material that uses aluminum as the base material and is seamlessly wrapped around a layer of copper. The metallurgical combination between copper and aluminum is used to manufacture copper-clad aluminum busbar composite materials, which are used to replace pure copper busbars and pure aluminum busbars. Best product. Because the busbar is used according to the length, the copper-clad aluminum busbar per unit weight is 2.45 times longer than the copper busbar with the same area, and the copper volume ratio of the copper-clad aluminum busbar is 15%. For example, the copper density is 8.89g / cm 3 , the aluminum density is 2.73g / cm 3 , the mass of copper in the copper-clad aluminum bar accoun...
