Application of fluid mechanics principle: Through reasonable design of pouring system, control of alloy liquid flow rate and other methods to achieve effective control of material flow.
Application of the principle of thermodynamics: By accurately controlling the temperature field distribution, the heat conduction performance of the material is affected, and then the material flow is regulated.
Computer simulation and optimization: The use of computer simulation technology to predict and optimize the material flow process to provide guidance for actual production.
Glue injection process: By injecting glue into the mold cavity, improve the filling performance, prevent porosity, cold insulation and other defects.
Melting welding process: The use of high temperature melting metal to fill the gap, to achieve a tight fit between the billet and the cavity.
Compression filling technology: By applying external pressure to promote the fluidity of metal materials, improve the filling effect.
Taking an aerospace metal forgings as an example, the application of material flow and filling control technology is analyzed. The forging is made of aluminum alloy material, which requires high strength and corrosion resistance. During the manufacturing process, material flow and filling control is achieved through the following steps:
Material flow control: Computer simulation technology is used to predict the flow behavior of alloy liquid and optimize the pouring system design. At the same time, the alloy liquid temperature and pouring speed are controlled to ensure the smooth flow of materials.
Filling control: The aluminum alloy material is closely bonded to the cavity using the melting welding process. By precisely controlling the welding temperature and welding speed, the filling effect is good, and the defects such as porosity and cold insulation are avoided. Compression filling technology is used to promote the fluidity of metal materials and improve the filling effect by applying external pressure.
