Abstract

The invention relates to a method for producing multi-element alloy by means of ring-pull cans. The method for producing the multi-element alloy by means of the ring-pull cans is characterized in that necessary raw materials, namely aluminum ingots, for producing traditional multi-element alloy are replaced by the ring-pull cans (the aluminum content of the ring-pull cans is 75% or over), and the contents of all elements are determined by adding the industrial waste such as waste residues and dedusting micro powder, so that reasonable proportioning is conducted. According to the method, the ring-pull cans are added, and various kinds of waste are heated, mixed and molten in a refining furnace by means of the heat of molten iron in a submerged arc furnace, so that a multi-element alloy product meeting user requirements is produced. The ring-pull cans, the waste residues and the waste powder are used for synthesizing the multi-element alloy, power consumption can be reduced by 2000-3500 KWH per ton of products, 12498.5 tons of standard coal can be saved each year, and 16000 tons of various kinds of waste powder can be disposed. The production cost is greatly reduced, resources and energy are greatly saved, and the additional value of the product is increased; a large quantity of industrial waste and residues are comprehensively utilized, and the purposes of saving energy, reducing consumption and achieving cyclic utilization are achieved; the national requirements for energy conservation and emission reduction are met, and a novel energy saving and consumption reducing approach is created for high-energy-consumption enterprises.

Description

technical field [0001] The invention belongs to the field of smelting multi-element alloys, aiming at the large quantity of waste articles in Ningxia area and the characteristics of easy purchase, and the method for producing multi-element alloys from unique mountain stones and other waste residues. Background technique [0002] A multi-element alloy is an alloy formed of two or more metal elements.
