High-strength galvanized steel strand

Abstract

The invention belongs to the technical field of stranded wire production, and particularly relates to a high-strength galvanized steel strand. Galvanizing equipment used in a stranded wire productionprocess comprises an outer shell, aqueduct boxes and reels. The aqueduct boxes are fixedly connected to the interior of the outer shell in a bilateral symmetry mode; zinc liquid is contained in the two aqueduct boxes; spiral winding discs are rotationally connected with the bottoms of the inner surfaces of the two aqueduct boxes; first motors are fixedly connected with of the lower surface of theouter shell on the positions of the two spiral winding discs; supporting plates are fixedly connected with the left and right side faces, close to the upper surface of the outer shell, of the outer shell; and the reels are arranged on the upper surfaces of the two supporting plates. According to the steel strand, the automatic spiral treatment of linear steel wire is effectively realized, the spiral steel wire is soaked in the zinc liquid, the soaking time of the steel wire in the zinc liquid is ensured as much as possible through the change of the screw pitch of the spiral steel wire, and thehot galvanizing quality is improved while the galvanizing efficiency is not influenced.

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
