Removal of crystallisation from aluminium casting parts, temperature and quality of return material
In the process of manufacturing Aluminum Casting Parts, it is necessary to effectively prevent the generation of pores. In the process of manufacturing, it is necessary to take effective measures to reduce the moisture of its raw materials as much as possible. In the process of processing aluminum castings, it is necessary to choose a reasonable Investment Casting process. Effectively strengthen its smelting quality management. All the raw materials used in Aluminum alloy castings and the tools needed for smelting need to be carefully removed from the surface of the oil and rust, and the quality of the alloy in the product and the return material also needs to be controlled in time, and the quality is poor. The returned material has broken metal scraps and so on. In general, the metal surface not only condenses its water, but also effectively interacts with the metal oxide film to form its crystal water, and then bakes at a low temperature at a certain temperature, so that its dissolved water and partial condensation can be effectively removed. of water. 
Aluminum investment casting can easily remove most of their crystals at 500 degrees. In the process of operation, it is necessary to shorten the smelting time as much as possible, so as to effectively reduce the amount of inhalation of its aluminum alloy, and the smelting of its products. The temperature must not be too high. Because the higher the temperature is, the larger the suction volume will be, so in general, the temperature will not exceed 800 degrees. During the smelting process, it must be controlled by a temperature measuring device, and it needs to be effective in the process of use. Control its deterioration time, the longer the deterioration time, the higher the deterioration temperature. The liquid surface of the Aluminum Alloy Investment Castings is protected by an oxide film, which can effectively prevent the molten metal from directly reacting with the moisture in the atmospheric water. In this way, the damage and deterioration of the oxide film should be avoided as much as possible during the smelting and casting process.
