Casting filtration technology analysis: how to ensure the quality of casting parts
First, the principle of casting filtration technology
Casting filtration technology refers to the casting process through the filter to remove impurities in the metal liquid, thereby reducing the defects in the casting, improve the quality of castings. These impurities mainly include metal inclusions, porosity, sand and so on.
Casting filters are generally made of quartz sand, wire mesh, ceramic fiber and other filter materials. Its working principle is to filter the impurities in the metal liquid through the filter's pore size and distribution, so that the quality of the casting parts poured at the end is more stable and reliable.
Second, the application of casting filtration technology
Casting filtration technology has become one of the essential technical means of modern casting production, commonly used in the casting of precision casting, high-quality casting and casting of important parts and components in the field of manufacturing.
In the automotive, aviation, aerospace and other fields, the requirements of the parts are very high, such as the requirements of lightweight, high strength, high temperature, high corrosion resistance and other characteristics. At this point, casting filtration technology can help casting enterprises to meet the requirements of product performance, thereby improving product competitiveness.
Third, the development trend of casting filtration technology
With the continuous development of science and technology, casting filtration technology is becoming more and more mature. In the future, casting filtration technology will pay more attention to integration and intelligence, such as the use of software-controlled digital filtration process, which can achieve fully automatic control, intelligent self-learning, data analysis and other functions to improve the efficiency and accuracy of the casting process.
In addition, the research and development of new filter materials is also an important development direction of casting filtration technology. For example, the application of nanotechnology materials such as carbon nanotubes can allow the casting filter to filter smaller impurities and further improve the performance of castings.
In short, the application of casting filtration technology helps to ensure the quality of casting parts, improve the competitiveness of casting enterprise products. With the development of science and technology and the application of new materials, casting filtration technology, efficiency and accuracy will be further enhanced.
Third, loss-in-weight casting
Loss-in-weight casting is a kind of advanced manufacturing technology applicable to the production of high-temperature alloy ultra-thin-walled rotor. In the production of intake pipe, loss-in-weight casting can be used to produce ultra-thin-walled, curved, complex shape of the intake pipe. Loss-in-weight casting can realize the directional solidification of high-temperature alloy, so that the intake pipe has better high-temperature performance and impact resistance. However, the cost of loss-in-weight casting is relatively high, and the manufacturing process also requires high equipment and technology.
In summary, the casting method of intake duct includes sand casting, precision casting and loss-in-weight casting. According to the shape, size and requirements of the intake pipe to choose the appropriate casting method can ensure the quality and performance of the intake pipe.
