- Effective solution of oxidizing slag in aluminum casting process
- Editor：Hangzhou Hongcheng Pml Precision Mechanism LtdDate：2016-04-19 17:22 Click：
aluminum casting is a production method, is a widely used industry, aluminum casting, aluminum casting, low pressure cast aluminum and so on are very good choice. Generally speaking, since it is not pure mechanization, there will be good and bad, so Hangzhou Hongcheng Pml Precision Mechanism Ltd how to tell people how to distinguish the quality of aluminum casting?
aluminum casting is often encountered with oxidation of slag, most of the medium is dispersed on the surface of aluminum castings, and some are distributed in the corner position that can not be found at the same time, and too many ports will be yellow or gray. It can be seen from mechanical processing that it can be found at the time of pickling or caustic washing:
the material in the furnace is not clean enough, the amount of the furnace material is too large; the design of the casting system is not reasonable; the slag in the aluminum casting alloy solution is not clean enough, and in the process of pouring it may be brought into the slag because of the unstandard operation; in the metamorphic treatment. The time is too long to prevent.
the material in the furnace is not clean enough, the amount of the furnace material is too large; the design of the casting system is not reasonable; the slag in the aluminum casting alloy solution is not clean enough, and in the process of pouring it may be brought into the slag because of the unstandard operation; in the metamorphic treatment. The time is too long to prevent. to solve these problems effectively, we need to master the reasonable standard casting speed and try to avoid getting the gas into it. In the core sand, it is not allowed to mix organic matter, which can reduce the gas volume of the material; improve the discharging function of the core sand and let the aluminum cast. It is becoming more and more powerful. In addition, it is necessary to choose a reasonable chill and improve the defects of gating system design so as to solve the appeal problem.
