Abstract

The invention relates to an aluminum alloy smelting refining agent. The aluminum alloy smelting refining agent consists of the following components by weight percent: 40-70% of potassium chloride, 15-30% of sodium aluminum fluoride, 1-10% of hexafluorobenzene, 5-15% of calcium sulphide and 5-20% of sodium sulfate. By adopting the aluminum alloy smelting refining agent, the hydrogen removing ability is enhanced, the content of hydrogen is reduced to 0.12ml / gAL, the impurity removing effect is obvious, after the refining agent is added, the refining production process is simple, and the utilization rate of the refining agent is improved.

Description

technical field

[0001] The invention relates to an aluminum alloy melting and refining agent. Background technique

[0002] In the modern automobile manufacturing industry, lightweight is a consensus indicator to measure the advanced technology development. Aluminum alloy has the advantages of low density, excellent thermal and electrical conductivity, and easy forming, so it is widely used. Aluminum alloy forming methods mainly include casting forming and deformation processing, among which casting forming is still a widely used forming method in modern aluminum alloy production.

[0003] In modern aluminum alloy casting, the complexity of product structure and simplification of processing technology have become the main ways to reduce production costs. For this reason, various compact casting processes have been developed, and die-casting technology has become one of the main molding methods. It has high production efficiency, It has the advantages of saving raw material...
