A high-strength galvanized steel strand

Abstract

The invention belongs to the technical field of stranded wire production, and specifically relates to a high-strength galvanized steel stranded wire. The galvanized equipment used in the production process of the stranded wire includes a casing, an aqueduct box and a reel; There are aqueduct boxes fixedly connected in left and right symmetry inside; the interiors of the two aqueduct boxes are filled with zinc liquid; the bottom positions of the inner surfaces of the two aqueduct boxes are all rotated and connected with spiral coils; the lower surface of the shell is on the two sides The positions of the two spiral coils are fixedly connected with the first motor; the left and right sides of the casing are fixedly connected with the support plate near the upper surface of the casing; the upper surfaces of the two support plates are provided with reels; through the present invention Effectively realize the automatic spiralization treatment of straight steel wire, by soaking the spiralized steel wire in the zinc liquid, and by changing the pitch of the spiral steel wire, the immersion time of the steel wire in the zinc liquid is guaranteed as much as possible without affecting the plating While improving zinc efficiency, the quality of hot-dip galvanizing is improved.

Description

technical field [0001] The invention belongs to the technical field of stranded wire production, in particular to a high-strength galvanized steel stranded wire. Background technique [0002] The stranded wire is realized by twisting a single wire around the stranded wire shaft at an equal angular velocity and moving forward at a uniform speed. Steel, copper and aluminum wires are commonly used. Steel, copper and aluminum wires can be twisted into various cross-sections of different specifications and types. When the wire core and stranded wire of wire and cable are produced, the surface of the raw steel wire needs to be galvanized. Galvanizing refers to the surface treatment of plating a layer of zinc on the surface of metal, alloy or other materials for aesthetics and antirust. technology. [0003] According to the production method of CN103952932B HDPE hot-dip galvanized prestressed steel strand for bridge cables, the hot-dip galvanized prestressed steel strand is used i...

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art and solve the problem in the prior art, when making stranded wires, it is first necessary to obtain galvanized steel wires. The galvanized effect of these steel wires directly affects the quality of the steel wires, which in turn affects the quality of the stranded wires. Quality, when steel wire is produced, the hot-dip galvanizing process is adopted. The galvanizing equipment in this process is a simple aqueduct box structure. A zinc layer is formed on the surface of the steel wire, but the production is in the following contradictions. If the transmission speed of the steel wire is increased, the production efficiency will be improved, but the immersion time of the steel wire in the zinc solution will be reduced, which is not conducive to the adhesion of zinc on the surface of the steel wire and affects the plating of the steel wire. The quality of zinc, but if the transmission speed of the steel wire is reduced, the production efficiency will be reduced, and the linear steel wire has a short galvanizing distance inside the aqueduct box, which is difficult to meet the galvanizing time requirements during galvanizing production. At the same time, it is mentioned in the above patent Double shafts are used inside the zinc pot to prolong the galvanizing distance, and at the same time adjust the vehicle speed to achieve the purpose of controlling the galvanizing time, but this method is difficult to effectively improve the galvanizing time and other problems. This invention proposes a high-strength galvanized steel strand Wire
