Abstract

The invention discloses an annealing method of an exterior aluminum wire of a composite-core soft aluminum stranded wire, comprising the following steps of S1, material selection: selecting an aluminum wire meeting specifications; S2, heating: heating the demanded aluminum wire and a heating furnace; S3, insulation treatment: standing the demanded aluminum wire in the heating furnace; S4, decreasing temperature treatment: decreasing the internal temperature of the heating furnace; S5, cooling: quickly placing the aluminum wire in a cold water basin; S6, drying: placing the cooled aluminum wire on a blow drying machine; S7, oil coating: coating the aluminum wire surface with oxidation-resistant oil. By the annealing method, the aluminum wire is relatively strong in plasticity to facilitate cutting and cold deformation and the aluminum wire stranding process can be completed, and thus the annealing method can be widely used and popularized, and economic and social benefits are increased.

Description

technical field [0001] The technical field of aluminum stranded wire processing technology of the present invention is specifically a method for annealing the outer layer aluminum-shaped wire of a composite core soft aluminum stranded wire. Background technique [0002] With the sustained and stable growth of my country's national economy, energy construction will become the key to sustainable development, and electricity is the main body of clean secondary energy capacity. Most of the energy must be converted into electricity before it can be effectively used. The origin of our country's energy Concentrated in the southwest and northwest regions, while a large amount of energy consumption is concentrated in the industrially developed southeast coastal regions. [0003] Annealing heat treatment is divided into complete annealing, incomplete annealing and stress relief annealing, diffusion annealing, spheroidizing annealing, recrystallization annealing, the mechanical properti...
