What is the removal temperature of aluminum castings?
Everyone has been exposed to the element of aluminum, and many products are made of aluminum. What is the crystal removal temperature of aluminum castings during the aluminum casting process? Aluminum castings need to effectively prevent the formation of pores during the production process, and effective measures need to be taken to minimize the amount during the production process. The moisture content of the raw materials, the process of aluminum castings processing requires a reasonable selection of the casting process, and effectively strengthens its smelting quality management.
All the raw materials needed for aluminum castings and the tools needed for smelting need to be carefully removed from the surface of the oil and rust. The quality of the alloy in the product and the reheating material also needs to be controlled in time, and the quality is poor. The recycled materials include metal scraps and so on.
In general, in addition to condensing its water, the surface of the metal effectively forms its crystal water with the oxide film of the metal, and then it is baked at a certain temperature at a low temperature, so that it can effectively remove the dissolved water and part of the condensed water. Of water.
Aluminum castings can easily remove most of their crystals at 500 degrees Celsius. In the process of operation, it is necessary to shorten the melting time as much as possible, so as to effectively reduce the amount of air intake of the aluminum alloy and the melting of the products. The temperature must not be too high.
Because the higher the temperature, the larger the air intake, 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 during use. Control the time of its deterioration, the longer its deterioration time, the higher its deterioration temperature.
The liquid surface of the aluminum alloy of the aluminum casting is protected by the 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 melting and casting process.
After aluminum castings are cast, they still need a certain processing technology, so that the surface accuracy is better, the gloss and brightness are improved, and then they are applied to our lives.
