Problems solved by technology

[0003] In the existing technology, the requirements of users were not fully considered in the process of this brand product, which caused many problems in the later die-casting parts. The most important thing is that the performance of this brand alloy cannot meet the high requirements of different users, which limits the application. expand
[0004] According to the existing production method to produce AlSi12Fe aluminum alloy ingots, the product is not easy to demould, the needle-shaped silicon structure is coarse, and the comprehensive performance of the die-casting product cannot meet the further quality requirements of the die-casting users.

Abstract

The invention relates to the technical field of aluminum alloys, in particular to a production method for improving comprehensive properties of an AlSi12Fe aluminum alloy ingot. The production method comprises the following steps of: melting, slagging off, melting silicon, checking a fracture structure, cooling, deslagging, refining, adding a modificator, degassing, standing, and casting an ingot. According to multiple tests on comprehensive properties of the AlSi12Fe aluminum alloy ingot produced by the method, the tested results are superior to those of the AlSi12Fe aluminum alloy ingot produced by an existing production method.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a production method for improving the comprehensive performance of AlSi12Fe aluminum alloy ingots. Background technique [0002] AlSi12Fe is an aluminum-silicon alloy in cast aluminum alloys. This grade of alloy has excellent casting properties and is widely used, such as automotive wiper joints. The production process of AlSi12Fe aluminum ingots in the prior art is too simple at present, and the production process is just a formality, so the product quality situation is not ideal. [0003] In the existing technology, the requirements of users were not fully considered in the process of this brand product, which caused many problems in the later die-casting parts. The most important thing is that the performance of this brand alloy cannot meet the high requirements of different users, which limits the application. expand. [0004] According to the existing production me...
