Vacuum casting equipment is a type of casting process equipment used for metal or alloy materials, mainly for manufacturing high-quality, complex-structured or specially required castings. During the vacuum casting process, gases and impurities can be effectively removed, the formation of pores and inclusions can be reduced, and the quality and performance of castings can be improved. Therefore, the key technologies of vacuum casting equipment are of vital importance.
I. Vacuum System Technology The vacuum system is the core component of vacuum casting equipment, and its performance directly affects the gas removal effect during the casting process and the quality of the castings. Key technologies include:
Pumping rate and final vacuum degree: The system is required to have a pumping rate and a reliable final vacuum degree to ensure the effective removal of gas during the pouring process.
Oil seal technology: High-performance vacuum pump oil seal technology is adopted to ensure the stable and reliable operation of the vacuum system.
Gas inlet valve technology: It is required that the inlet valve be reasonably designed, have good sealing performance, and be capable of quickly controlling the gas inlet to ensure the stability of the system under different process conditions.
Second, smelting and casting technology: For vacuum casting equipment, the smelting and casting processes are crucial technological links that directly determine the quality and performance of the castings. Key technologies include:
Smelting process control: The smelting system is required to have high-precision temperature control and composition analysis technology to ensure accurate control of alloy composition and temperature.
Pouring process control: The pouring system is required to have flow control and pressure control technologies to ensure the uniform flow and solidification of the metal during the pouring process.
Casting technology for refractory metals such as titanium alloys: For refractory metals like titanium alloys, the casting system is required to have high-temperature, high-pressure, and high-precision control technologies to ensure the quality and performance of the castings.
Iii. Intelligent Control Technology With the advancement of science and technology and the development of industrial automation, vacuum casting equipment is gradually moving towards intelligence. Key technologies include:
