Problems solved by technology

In the actual recycling of scrap aluminum, the waste aluminum is smelted first to remove all impurity components to obtain relatively pure aluminum for ingot casting, and the regenerated aluminum ingots are sold to downstream companies, and secondary melting is performed to add alloy components according to product requirements. , casting to make products, this two-melting first removes the alloy and then supplements the alloy process, which is a serious waste of energy, and many alloy composition resources are not rationally utilized

Abstract

The invention relates to the field of waste metal recovery, and particularly relates to an energy-saving and cost-reducing technology for directly utilizing smelting of aluminium scraps. Two smelting procedures of smelting and utilizing secondary aluminium are replaced by one smelting procedure by virtue of changing the traditional secondary aluminium smelting technology, so as to finish the overall process from smelting to utilizing. Energy conservation and consumption reduction are greatly achieved by reducing two smelting procedures, and purifying and adding alloying components. The method provided by the invention not only is simple in flow, but also can be used for saving energy source, and reducing emission of wastes.

Description

technical field [0001] The invention relates to the field of waste metal recycling, in particular to an energy-saving and consumption-reducing process for directly utilizing waste aluminum smelting. Background technique [0002] At the present stage, while the economy is developing rapidly, the over-exploitation of resources and the depletion of resources have become bottlenecks to curb development, and if a large amount of scrap metal produced every year is not recycled, it will cause serious pollution and aggravate the depletion of resources. Therefore, now The recycling of scrap metal has been paid more and more attention by various countries. Facts have proved that compared with traditional ore smelting, secondary smelting has obvious energy-saving effects. The smelting process of scrap steel can save 74% of energy and reduce 86% of air pollution; the smelting of scrap copper can save 85% of energy; Smelting can reduce energy consumption by 95%; smelting waste lead can ...
