Aluminum Alloy Casting Process Performance Requirements

- Jul 10, 2017-

In aluminum alloy casting its products are the most widely used in the use of his and other alloys is no way to compare, because of its aluminum alloy casting the different components in the use of the alloy shown in the physical and Chemical performance is different.

Aluminum alloy casting in the production process of its crystallization process is not the same, in use must be for its aluminum alloy characteristics, a reasonable choice of casting method so as to effectively prevent the scope of the license to effectively reduce the casting of defects generated The

The performance of the aluminum alloy casting process is usually understood in the process of being used as a combination of those properties that are most prominent in the process of cooling, crystallization and crystallization of the equipment. The properties of the aluminum alloy depend on the composition of the alloy, but also Casting factors, alloy heating temperature, the complexity of the mold, pouring riser system, gate shape and so on.

The flowability of aluminum alloy casting mainly refers to the ability of the alloy liquid to fill the mold, the product of its mobility, to a certain extent, the effective decision whether the alloy casting complex castings. The eutectic alloy is the best in aluminum alloy.

There are many factors that affect the flowability of aluminum alloy casting, mainly the composition, temperature and solid particles of metal oxides, metal compounds and other pollutants in the alloy liquid, but the external fundamental factors are pouring temperature and pouring pressure.

In the actual production of aluminum alloy casting, in addition to strengthening the melting process, the alloy must also improve the casting process, without affecting the quality of castings under the premise of increasing the pouring temperature, to ensure the mobility of the alloy.
