[0002] At present, as a composite wire, the steel-clad wire is intended to have both the electrical conductivity of stainless steel and the tensile strength and elongation of steel. Although there are many related introductions, the actual obtained steel-clad wire may have too large a specific gravity. , the purpose of saving stainless steel is not achieved, or the tensile strength and elongation are not ideal.
[0003] On the other hand, the traditional method of manufacturing ladle 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] Firstly, a preferred method for manufacturing steel / 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 numerical values in the following examples.
[0023] First, the stainless steel strip is coated 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-type vacuum annealing treatment; after tank-type vacuum annealing treatment The final 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 kept in the drawn state for continuous annealing by electric heating box Processing: after stew-type continuous annealing treatment, and then through multiple drawing, forming wire...

Abstract
The present invention discloses one kind of composite steel / steel wire and its making process. The making process includes coating carbon steel core with stainless steel 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 steel / steel wire with required specific weight, elongation, conducting performance and tensile strength.
Description
technical field [0001] The invention relates to a steel / steel composite wire and a manufacturing method thereof. Background technique [0002] At present, as a composite wire, the steel-clad wire is intended to have both the electrical conductivity of stainless steel and the tensile strength and elongation of steel. Although there are many related introductions, the actual obtained steel-clad wire may have too large a specific gravity. , the purpose of saving stainless steel is not achieved, or the tensile strength and elongation are not ideal. In a word, the stainless steel-clad thin wire with low price and meeting the standard requirements has not been produced on the market so far. [0003] On the other hand, the traditional method of manufacturing ladle 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 ca...
