Regenerated aluminum strong-magnetism iron-removing device and method thereof

Abstract

A regenerated aluminum high-efficiency iron-removing device and a method thereof are characterized in that: 1) two hollow stirring rods are selected, the two stirring rods are allowed to be welded in parallel and be fixed on an iron-made sealed container, a water cooling circulation system is formed in the cavities of the stirring rods and the interior of the sealed container, the strong-magnetism iron-removing device with water cooling is prepared, and the exterior is coated with heat resistant asbestos cloth; 2) when iron removal of a regeneration aluminum molten liquid is required, the water cooling circulation system of the strong-magnetism iron-removing device is started, iron in the molten aluminum is absorbed and cleared up by utilizing a magnetic force of a strong magnet during stirring; and 3) the strong-magnetism iron-removing device can be recycled. The method is simple, is convenient for practical operation, good in iron removing effect and low in cost, and quite easily removes the impurity iron by utilizing magnetism adsorption. Moreover, with adopting of the water cooling circulation system, the magnetism of the magnet is ensured to not lose due to the high temperature, so that the strong-magnetism iron-removing device can be recycled.

Description

technical field [0001] The invention relates to the technical field of aluminum smelting, in particular to a regenerated aluminum strong magnetic iron removal device and method. Background technique [0002] Recycled aluminum is an indispensable resource for the sustainable development of the aluminum industry. Compared with the production of primary aluminum, each ton of recycled aluminum can save 95% of energy and greatly reduce harmful emissions such as carbon dioxide. It not only saves energy and purifies the environment, but also greatly Reducing the production cost of aluminum alloy products has good social and economic benefits. The world's recycled aluminum accounts for 45% of the total demand in the aluminum market. The sources of raw materials for scrap aluminum recycling are complex and diverse, and a certain amount of inclusions will inevitably be brought in, especially the relatively high content of iron, which will easily lead to the failure of aluminum alloy i...

Problems solved by technology

The world's recycled aluminum accounts for 45% of the total demand in the aluminum market. The sources of raw materials for scrap aluminum recycling are complex and diverse, and a certain amount of inclusions will inevitably be brought in, especially the relatively high content of iron, which will easily lead to the failure of aluminum alloy ingots. Defects such as porosity and slag inclusion in the middle have a great impact on the performance of aluminum, and high-iron aluminum cannot be used directly

In the process of producing aluminum alloy from secondary aluminum, iron removal is a very important step. The traditional method is to remove iron by adding iron remover, which is costly and will produce other substances
