Mold filling process refers to the flow process of liquid metal in each component of gating system and mold cavity.
For iron mold sand coated casting, generally, its cooling speed is fast, the apparent shrinkage time is long, and the
The gating system, riser and chill must be designed according to the solidification principle of castings in sand casting process.
Foundry industry plays an important role in the development of national economy. In recent years, the output and quality of
The mold free digital precision forming machine is used to realize the milling and forming of glass sand and resin
The filling process and solidification process of typical box castings are simulated by using the casting process numerical simulation software.
1. Simulation of mold filling process of excavator rear axle casting After improving the process, the mold filling process of
1. Optimization of gating system In view of the turbulent flow caused by the unstable flow of liquid metal in

1. Cause analysis The modified ductile iron casting process is drawn into a three-dimensional diagram by 3D software, and then
In the actual production of castings, there will be many defects, so the design and optimization of casting process scheme
① Upgrading of molten steel smelting equipment. Open hearth steelmaking was eliminated in the metallurgical industry four years ago, and
According to the characteristics of sand mold casting process, a low carbon evaluation model is proposed, which can effectively evaluate
When the volume fraction of carbide with high hardness in the solidification structure of Cr based alloy is 20 ~
The whole contour of eutectic structure in hypereutectic chromium cast iron is very similar to that of Hypoeutectic and eutectic
According to the different carbon content, the solidification structure of chromium alloys can be divided into hypoeutectic, eutectic and hypereutectic.
The solidification structure of chromium alloys is closely related to the content of C and Cr in them. According to
At present, FDM / FEM integration is widely used in the calculation system of temperature and stress field in casting
