aluminum alloy melting

2.1 Overview
As we all know, aluminum alloy is extremely sensitive to melting conditions. After melting, the temperature and distance between overheating and thermal insulation have a lot to do with the quality of aluminum liquid. During the melting process, the atmosphere of the mountain is not adapted, which will also cause a large amount of inhalation and form a slag. For example, when melting in the oxidation atmosphere, the metal is over-burning, and the melted aluminum forms a large amount of residue, which may pollute the metal liquid. When the aluminum liquid is melted in the restoring atmosphere, it will absorb hydrogen. After the aluminum liquid is poured and solidified, the casting is loose and pore defects. Therefore, both atmosphere is not suitable, and the restoration atmosphere is particularly harmful. It is best to melt in the mountains atmosphere.
The control of ingredients in smelting is also important. Because the mechanical and physical properties of aluminum alloy are related to the alloy composition, the alloy composition also affects the casting and processing process. During the smelting process, iron, or. Manganese elements can synthesize complex products. Blood is a high-hardness, high-melting point compound. It is usually deposited in the lower part of the aluminum to form a residue. It is one of the sources of the hard point of the casting. Its harm is a tool for damaging and complex and expensive, which causes a large number of workpieces to error in processing. To prevent the formation of this hard point, the slag coefficient should be calculated based on the melting conditions (thermal insulation conditions). The calculation formulas determined and adopted according to the production experience of domestic and foreign factories are as follows:
wyr ++ 3 itc [w | 75%
In other words, when the slag coefficient does not exceed 1.75%, it can prevent the formation of scum.
