Problems solved by technology

[0002] In recent years, China's galvanized steel strand industry has developed rapidly, and domestic production technology has been continuously improved. In order to obtain greater investment returns, domestic galvanized steel strand enterprises have continuously improved their production scale and product quality. The requirements for stranded wire are getting higher and higher, specifically in terms of strength, toughness, tensile strength and corrosion resistance. -Hydrochloric acid washing-water washing-solvent treatment-drying-hot-dip galvanizing-wiping-receiving-finished products, the steel strands produced are used in daily life, such as galvanized steel strands for overhead cables, However, because the overhead cable is completely exposed to the natural environment, the wind and rain environment is harsh, and some human factors, it is easy to break, corrode, and have a short service life. In addition, because the surface is not very smooth, it is easy to cause accidental injury to personnel, so A galvanized steel strand used for overhead guy wires and its production process that can overcome the above shortcomings and provide assistance for people's lives has become a technical problem that those skilled in the art need to solve urgently

Abstract

The present invention discloses a zinc-plating steel strand for overhead guying, and a production process thereof, wherein the zinc-plating steel strand comprises seven steel wires with a diameter of 6.6 mm, one of the steel wires is positioned on the center of the circumference while other six steel wires are uniformly distributed on the same circumference, the seven steel wires are closely attached, the outer sides of every steel wire are respectively provided with a zinc-plating layer, and a layer of a rubber sleeve is covered outside the zinc-plating layer. The zinc-plating steel strand has characteristics of high strength, good toughness and strong corrosion resistance, and has high safety through sleeving the protection sleeve on the surface. In addition, the zinc-plating steel strand production process has characteristics of simple process, easy operation and low cost.
