Aluminum alloy gravity casting is an indispensable part of the aluminum alloy casting process. Due to the large volume and weight of the equipment used in casting, it is relatively difficult to maintain the equipment during casting. Therefore, in normal circumstances, when performing gravity casting of aluminum alloys, attention should be paid to daily maintenance to reduce mechanical equipment failures. incidence rate. So what needs to be done when gravity casting of aluminum alloys is carried out? Before the gravity casting of aluminum alloy, the lubrication of the machine should be done to maintain the normal use of the parts. At the same time, the external cleaning of the casting equipment should also be done to avoid the casting equipment from being unable to work properly due to excessive dust.

At the same time, after the aluminum alloy gravity casting, it is necessary to regularly check the various parts of the casting equipment.If there is serious damage and wear, it should be replaced in time to avoid affecting the normal production. During gravity casting of aluminum alloy, it is also necessary to regularly process the waste aluminum water in the furnace to ensure that the furnace is in a clean state when gravity casting of aluminum alloy is performed. In addition, the alumina in the furnace should also be removed regularly. During the use of the casting equipment, it is necessary to inspect and maintain the casting equipment every day, not only to ensure the stability of the mechanical equipment in use, but also to ensure that the potential hidden dangers of the machine can be eliminated in time during the maintenance process.

Nowadays, there are mainly two kinds of Rubber Tracks aluminum alloy casting methods, one is aluminum alloy gravity casting, and the other is aluminum alloy sand casting. These two casting methods have their own advantages in use. In the production of aluminum alloy castings in many industries, not only aluminum alloy gravity casting is used, but also aluminum alloy sand casting is occasionally used.While many manufacturers today use both methods to produce aluminum alloy castings, many are unaware of the difference between gravity casting and sand casting. In fact, the castings produced by the aluminum alloy gravity casting machine have uniform wall thickness, high tissue density, smooth inner and outer surfaces, consistent external dimensions, and fast finishing speed.

The castings produced by aluminum alloy sand casting are prone to slag inclusion, blisters and looseness, rough inner and outer surfaces, inconsistent external dimensions, and slow and inaccurate finishing. In terms of yield, the qualified rate of gravity casting is higher than that of sand casting, and it also has the advantages of low pouring temperature, low pollution and low noise. However, when aluminum alloy sand casting is performed, a large amount of flue gas will be generated, which will cause relatively large pollution and generate more noise. It is precisely because of this that the gravity casting method has been well developed and popularized, and the aluminum alloy sand casting technology is gradually withdrawing from the industrial stage.
