Aluminum-clad steel core aluminum stranded wire is an effective power transmission material, and its manufacturing process is the key. This article will introduce the production process of aluminum-clad steel-core aluminum stranded wire in order to better understand the advantages and characteristics of this material.
Raw materials for 1. production
The raw materials for the production of aluminum-clad steel core aluminum stranded wires include aluminum, steel wire and copper. Among them, aluminum is the main raw material, because of its good electrical conductivity, while lightweight is also an advantage. Steel wire is used to increase the strength and rigidity of the strands, and copper is used to improve electrical conductivity and corrosion resistance.
Production process of 2. aluminum-clad steel core aluminum stranded wire
The production process of aluminum-clad steel core aluminum stranded wire is mainly divided into the following steps:
Steel wire screwing: First, the high-strength steel wire is processed through a series of processes, including screwing and galvanizing, to increase its strength and corrosion resistance.
Aluminum cladding: The surface of the steel wire is coated with a layer of aluminum. This process is called aluminum cladding. Its purpose is to protect the steel wire from oxidation and corrosion, and it can also increase the adhesion of aluminum and steel wire.
Stranding: The aluminum-clad steel wire is twisted by mechanical twisting to form a stranded wire. In this process, the stranding length, direction and the number of stranding layers of the stranded wire will affect the performance of the stranded wire.
Extrusion: The surface of the stranded wire is coated with a layer of aluminum. This process is called extrusion. Its purpose is to protect the stranded wire from damage and corrosion, and it can also increase the adhesion of aluminum and stranded wire.
Heat treatment: Heat treatment of the extruded strands to eliminate internal stress and improve the strength and stability of the material.
Packaging: The heat-treated aluminum-clad steel core aluminum stranded wire is cut and packaged according to a certain length and specifications for transportation and use.
3. process optimization and control
The production process of aluminum-clad steel-core aluminum stranded wire needs to be optimized and controlled to ensure its performance and quality. Among them, the process optimization mainly includes the optimization of process parameters such as steel wire, aluminum package and stranded wire to improve the adhesion and strength of aluminum package and stranded wire. The process control mainly includes the control and monitoring of the entire production process to ensure that the production of aluminum-clad steel core aluminum strand conforms to relevant standards and specifications.
In terms of process optimization, the pretreatment of the steel wire is very important, because it directly affects the quality of the aluminum package. If the surface quality of the steel wire is not good, the adhesion between the aluminum clad and the steel wire will be reduced, resulting in reduced strength and stability of the stranded wire. Therefore, in the pretreatment process of the steel wire, proper cleaning and degreasing treatment should be carried out to ensure that the surface of the steel wire is clean, smooth and has good aluminum-clad adhesion. In terms of the process parameters of aluminum-clad and stranded wires, the thickness of aluminum-clad, the pitch and the number of layers of stranded wires will affect the performance of aluminum-clad steel-core aluminum stranded wires. In the process of process optimization, it is necessary to realize the performance of aluminum clad and stranded wire through reasonable parameter selection and adjustment.
