Problems solved by technology

In fact, with the increase of aluminum content, the adhesion of the coating is stronger, and the wear resistance and corrosion resistance are better. The structure is uniform and the resistance to plastic deformation increases, so the higher the aluminum content, the more difficult it is to draw into wire

example 1

[0021] Zinc-aluminum alloy, wherein the atomic percentage of metal aluminum in the alloy is 55%. First, 663g of zinc ingots containing 99.99% of zinc and 337g of aluminum ingots containing 99.7% of aluminum are placed in a vacuum induction melting furnace to melt into ZnAl 55 For alloy ingots, the melting temperature is 650°C, the dummy speed is 50-80mm / min, the cutting size is Φ18-30mm, and the lubricant is high-quality carbon ink. Then put the finished alloy ingot into a rotary forging machine for rotary forging to make its composition uniform. The heating temperature of the rotary forging is 400°C, the forging temperature is 400°C, and the final forged size is Φ8-15mm. Then put the forged alloy wire into the drawing equipment for medium-temperature drawing. At this time, the heating temperature is 350°C, the drawing temperature is 300°C, and the finally drawn alloy wire has a specification of Φ2.5-4mm.

Abstract

The invention supplies allumen and its manufacturing method. The atom percentage of its components metallic aluminum is 41-55%. The rest is zinc. The method includes the following steps: using level continuous casting after smelting for zinc and aluminum to gain Zn Al alloy bar; high temperature rotary swaging or hot rolling; middle temperature drawing to form alloy filament. The invention also supplies the application of the alloy as steel surface anticorrosive.

Description

technical field [0001] The invention relates to a zinc-aluminum alloy wire, its manufacturing method and its application, and belongs to the field of light alloy materials and corrosion and protection. Background technique [0002] Metal corrosion and anti-corrosion problems are closely related to the development of modern science and technology and people's lives. Almost all metal materials are used in a certain environment. Metal materials are affected by the environment during use, and are often gradually damaged or degraded over time, which is usually called "corrosion" or "aging". More than 90% of the use of metal materials is steel. The annual corrosion rate of existing steel and metal equipment in the world is about 10%. The annual loss due to corrosion in the world is about 700 billion U.S. dollars. The loss accounts for about 2% to 4% of the total output value of the national economy. It can be seen that the corrosion problem of metals, especially steel, is very se...
