Problems solved by technology

If these waste metals are discarded at will, it will not only cause environmental pollution, but also waste limited metal resources.
[0003] At present, there are more dross on the scrap metal in the recycling process of scrap metal, that is, there is a lot of ash and dust mixed with the scrap metal in the recycling stage, and the ordinary recycling processing has not been properly treated, making it difficult to remove it in subsequent processing, making the scrap metal processed into semi-finished products The metal content is impure, the quality is not high, and it does not meet the requirements for the use of metal products. It also brings difficulties to subsequent processing procedures, increases processing energy consumption, and increases the cost of scrap metal recycling and processing.

Abstract

The invention discloses a recovery processing and purification method for waste metal. The recovery processing and purification method for the waste metal comprises the following steps: pretreatment,forging and briquetting, smelting, mold forming and detection. The recovery processing and purification method for the waste metal has the following advantages: the waste metal is recovered and purified through the technical processes of pretreatment, forging and briquetting, smelting, mold forming and the like, the technical flow is shortened, the treatment time is reduced, the turnover and circulation of the metal are accelerated, and the utilization efficiency for the metal is increased; and different impurities in the waste metal are removed by charging different reaction gases, a good effect is achieved, and the smooth progress of the subsequent processing procedure is guaranteed, so that the processing energy consumption is reduced, the processing cost is saved, the processing quality for the waste metal is guaranteed, and the processing economic benefits of the waste metal are increased.

Description

technical field [0001] The invention relates to the technical field of scrap metal recycling, in particular to a recycling, processing and purification method of scrap metal. Background technique [0002] The phenomenon of new and old replacement in the use of metal products is inevitable. Due to the corrosion, damage and natural elimination of metal products, a large amount of scrap metal is produced every year. If these waste metals are discarded at will, it will not only cause environmental pollution, but also waste limited metal resources. [0003] At present, there are more dross on the scrap metal in the recycling process of scrap metal, that is, there is a lot of dust and dust mixed with the scrap metal in the recycling stage, and the ordinary recycling processing has not been properly treated, making it difficult to remove it in subsequent processing, making the scrap metal processed into semi-finished products The metal content is impure, the quality is not high, a...
