[0002] At present, the copper-clad steel conductor is a composite conductor whose purpose is to have both the electrical conductivity of copper and the tensile strength and elongation of steel. Although there are many related introductions, the real copper-clad steel conductor may have too large a , the purpose of saving copper is not achieved, or the tensile strength and elongation are not ideal.
[0003] On the other hand, the traditional method of manufacturing copper-clad steel composite wire usually adopts one-time annealing treatment. With this traditional manufacturing method, no matter how the annealing treatment conditions are set, the expected ideal tensile strength and elongation cannot be obtained. rate, the final product performance is not very ideal

Embodiment 1
[0022] First, a preferred method for manufacturing copper / steel composite wire of the present invention is provided, but those skilled in the art can easily infer that the relevant numerical range of the manufacturing method of the present invention is not limited to the specific values in the following examples.
[0023] First, the copper strip is wrapped on the carbon steel wire core to make a composite billet, the diameter of the composite billet is 1.5-2.6mm, and then the composite billet is put into a vacuum tank for tank vacuum annealing treatment; after tank vacuum annealing treatment The composite billet is drawn for multiple times, and at the same time as the final drawing of the composite wire with a diameter ranging from 0.60 to 1.50 mm, the composite wire is in the drawn state to be subjected to continuous annealing through an electric heating box. After the continuous annealing treatment of the stewing type, the forming wire with a diameter ranging from 0.08 to 0...

Abstract
The present invention discloses one kind of composite copper / steel wire and its making process. The making process includes coating carbon steel core with copper band to form composite blank and vacuum annealing of the composite blank in a vacuum tank; drawing for several times and continuous annealing during the last drawing; twisting to form stranded wire and on-line annealing in fine pipes; and winding onto a take-up bobbin to obtain final product. The making process can obtain composite copper / steel wire with required specific weight, elongation, conducting performance and tensile strength.
Description
technical field [0001] The invention relates to a copper / steel composite wire and a manufacturing method thereof. Background technique [0002] At present, copper-clad steel wire is used as a composite wire, and its purpose is to have both the electrical conductivity of copper and the tensile strength and elongation of steel. Although there are many related introductions, the real copper-clad steel wire or the specific gravity is too large. , the purpose of saving copper material is not achieved, or the tensile strength and elongation are not ideal. In short, there is still no copper-clad steel thin wire that is cheap and meets the standard requirements on the market. [0003] On the other hand, the traditional method of manufacturing copper-clad steel composite wire usually adopts one-time annealing treatment. With this traditional manufacturing method, no matter how the annealing treatment conditions are set, the expected ideal tensile strength and elongation cannot be obt...
