[0002] At present, the copper-clad iron alloy 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 iron alloy. , 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 iron alloy 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] Firstly, a preferred method for manufacturing copper / iron alloy 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 numerical values in the following examples.
[0023] First, the copper strip is coated on the iron alloy 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-type vacuum annealing treatment; after tank-type vacuum annealing treatment The composite blank is drawn multiple times, and at the same time as the last drawing of the composite wire with a diameter ranging from 0.60 to 1.50 mm, the composite wire is in the drawn state and is subjected to continuous annealing treatment through an electric heating box ;After the continuous annealing treatment of stewing type, and then through multiple draw...

Abstract
The present invention discloses one kind of composite copper / ferroalloy wire and its making process. The making process includes coating ferroalloy 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 / ferroalloy wire with required specific weight, elongation, conducting performance and tensilestrength.
Description
technical field [0001] The invention relates to a copper / iron alloy composite wire and a manufacturing method thereof. Background technique [0002] At present, the copper-clad iron alloy 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 iron alloy. , the purpose of saving copper is not achieved, or the tensile strength and elongation are not ideal. In a word, copper-clad iron alloy thin wires with low price and meeting the standard requirements have not been produced on the market so far. [0003] On the other hand, the traditional method of manufacturing copper-clad iron alloy 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 performance of the final product is not ideal.
