Abstract

A processing method of a steel wire for an armored cable comprises the following steps: peeling and coating treatment of a raw material wire: carrying out coating treatment on the surface of the wire in a coating tank filled with a coating agent solution, and then drying; the wire obtained after coating treatment and drying is subjected to single-pass or multi-pass drawing on a wire drawing machine, the total area reduction rate ranges from 35% to 42%, and the wiring speed is controlled to range from 300 m / min to 400 m / min in the rough drawing process; rough annealing is conducted, specifically, the wire rod subjected to rough drawing is annealed in an annealing furnace, the annealing temperature is 980-1000 DEG C, and quenching is conducted to the room temperature after online annealing; fine drawing: performing fine drawing on the wire after rough annealing, and performing single-pass or multi-pass drawing on a wire drawing machine with the total area reduction rate of fine drawing being 45-65%; fine annealing: carrying out online annealing at 1000-1080 DEG C on the wire rod subjected to fine drawing, and quenching to room temperature after carrying out online bright annealing; and sanding and packaging: carrying out surrounding type grinding and polishing on the finely drawn wire rod on an abrasive belt grinding machine to obtain a final finished product. The cable has the advantages of good mechanical property and tensile strength and low possibility of causing high temperature of the cable.

Description

technical field [0001] The present application relates to the technical field of cable steel wire, in particular to a processing method of steel wire for armored cables. Background technique [0002] The construction of submarine cable projects is limited by conditions such as geography, marine engineering, and construction equipment. The construction of the project involves a wide range of technical fields, large investment scale, and complex construction techniques. The project construction period can generally be divided into two stages. The pre-construction work mainly involves engineering design, submarine cable routing selection, submarine cable manufacturing and transportation. The project construction period mainly includes submarine cable routing positioning, submarine cable laying, submarine cable protection, land Equipment installation, testing and commissioning, project acceptance. Specifically, it is mainly reflected in the following aspects: [0003] Great le...
