Vacuum distillation method for magnesium alloy

Abstract

The invention discloses a vacuum distillation method for magnesium alloy. Waste scraps of the magnesium alloy are distilled under the vacuum degree of 0.8Pa so as to recycle high-risk waste magnesium, wherein the distillation temperature is 580 DEG C, the condensing temperature is 330 DEG C and the distillation time is 6 hours. The vacuum distillation method has the advantages of simple production process, high recovery rate of magnesium alloy, economy, feasibility, relatively low energy consumption, completely green metallurgy and great conservation of social wealth and resources and is environment-friendly, and a product has qualified performance. Therefore, the vacuum distillation method has wide application prospect and high application value.

Description

technical field [0001] The invention relates to a vacuum distillation method for magnesium alloys, in particular to a method for recycling waste magnesium alloys by adopting vacuum distillation. Background technique [0002] Magnesium alloy is the lightest commercial metal structure material, which has the advantages of small specific gravity, high specific strength and specific stiffness, good damping and thermal conductivity. In recent years, magnesium alloy materials have been widely used in the fields of aerospace, automobile manufacturing and electronics, followed by increasing magnesium alloy waste. The generation of magnesium and magnesium alloy waste not only comes from the production and processing of products, but also produces a large amount of waste when magnesium alloy products reach their service life. [0003] At present, the recycling methods for these magnesium alloy scraps mainly adopt flux refining method and flux-free refining method and so on. However,...

Problems solved by technology

Although the vacuum distillation method is a simple production process, relatively low energy consumption, environmental protection and pollution-free, and meets the requirements of green metallurgy, its research is limited to the analysis of theoretical feasibility and automatic control of equipment, and has no research on magnesium alloys. A practical study of distillation recovery

At the same time, for the distillation and purification of magnesium alloys, the higher the condensation temperature, the higher the purity of the magnesium alloys will be, but the less condensation (that is, the recovery) will follow, which obviously restricts the technology from being practical. The paradox of the application

Moreover, if the condensation temperature is increased blindly in order to simply improve the recovery purity of the magnesium alloy, it will lead to a large amount of energy consumption, resulting in an increase in the recovery cost.
