  • Solving method of oxidizing slag in aluminum casting
  • Editor：Hangzhou Hongcheng Pml Precision Mechanism LtdDate：2016-01-06 17:49 Click：
    Hangzhou Hongcheng Pml Precision Mechanism Ltd are made of aluminum castings by aluminum casting, die-casting, high strength casting and so on. It is a device device for the obtained pure aluminum or aluminum alloy.
    aluminum casting is often encountered with oxidation slag, most of which are dispersed on the surface of aluminum castings, and some are distributed in the corner position that can not be used for the same period, and too many ports in the port will be yellow or gray. It can be seen from mechanical processing that it can be found in the pickling or caustic washing process:  
    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.
