Problems solved by technology

However, due to the backwardness of its traditional technology and technical defects, after being drawn into thin wires, its elongation rate is not as good as that of pure copper, and its application fields have been restricted, such as being used as a five-category, super-category, six-category, seven-category cable. Inner conductors and coaxial cable shielding layer braided materials have not been popularized and applied because their elongation cannot meet the corresponding requirements. It is required to have higher torsional thrust than coaxial cable shielding layer braided mesh material, which is closely related to the elongation of the wire

Abstract

The invention discloses a production process of a copper-clad steel signal line for blasting. The production process comprises the following steps: material selection, decladding, drawing, wire coiling and taking up, high-temperature tempering, pickling, water washing, acid electrolysis, water washing, pre-pretreatment Treatment of electrodeposition, water washing, thick treatment electrodeposition, water washing, pretreatment electro-deposition, water washing, post treatment electro-deposition, water washing, oxidation treatment, drying, wire take-up, fine drawing and tempering to obtain a finished product copper-clad steel line. A steel wire is thinned by once drawing, thereby avoiding the problem of insufficient ductility caused by multiple times of drawing, the strength of the line isgreatly improved by the twice high-temperature tempering, furthermore, the surface of the line is bright, and the resistance is reduced, the copper-clad steel signal line has high strength and low cost, and can be widely applied to occasions with strict requirements for mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of blasting signal wires, and in particular relates to a production process for blasting copper-clad steel signal wires. Background technique [0002] Blasting refers to a construction method that uses explosives to excavate earth and stone, demolish or destroy foundations, buildings, and structures, generally including rock and soil blasting, demolition blasting, metal blasting, explosive processing, seismic exploration blasting, oil and gas wells Blasting, high-temperature blasting, underwater blasting and other blasting, so the signal line for blasting needs to move frequently with equipment and instruments in a complex environment, and has high requirements for the speed, reliability, electromagnetic shielding performance, and mechanical properties of the signal line. It has also shifted from coaxial cable to twisted pair and optical fiber. Twisted pair has developed from the original category 1, category ...
