The traditional casting process mostly depends on a large number of empirical test data. Casting numerical simulation is an important means to make the casting process from empirical test to scientific guidance. The use of simulation can w predict the product quality, determine the best process scheme, reduce the...
The improved process scheme is adopted for the hook body steel casting to simulate the mold filling and solidification process. The interface heat transfer coefficient between the insulation riser and the sand mold is 100W / (M2 · K), and other settings remain unchanged. During the mold filling process,...
Figures 1 to 3 show the simulation analysis results of the casting solidification process of the hook tongue. Figure 1 shows the analysis results of cross-section temperature at different times during the solidification process of hook tongue. The solidification sequence is from the outer side of the hook wrist...
Figure 1 to figure 4 show the simulation analysis results of the hook tongue filling process. Figure 1 shows the filling sequence and temperature analysis results of each part at different times during the filling process of the original hook tongue process. It can be seen from Figure 1...
According to the technical requirements of hook body steel castings, in order to simplify the casting process and ensure the casting quality, the following casting process optimization scheme is proposed: (1) Change the introduction position of the inner gate and place it on one side of the hook body...
1. Model transformation and mesh generation The coupler knuckle and its casting process are modeled by UG, and then the steel castings and sand core models of coupler knuckle are derived by using Parasolid interface file format XT mesh file, and then import them into meshcast for finite element...
The steel castings of coupler body are the key parts of vehicle connection, which have a significant impact on driving safety. During the driving process of freight cars, the steel castings of coupler body will be frequently pulled and compressed. The coupler head is the main stress part, and...
The casting methods mainly include sand mold gravity casting, lost foam casting, pressure casting, centrifugal casting, etc. the cast steel joint of the four branch pipes adopts sand mold gravity casting. The casting process is divided into five steps: melting, molding, casting, heat treatment and post-treatment. In the molding...
There are many software for casting simulation, such as FLOW-3D, MAGMAsoft, ProCAST, Huazhu CAE, etc. Casting simulation is carried out by ProCAST software. As the flagship product of ESI group’s thermophysical comprehensive solution, ProCAST is the most integrated of all casting simulation software. It takes the lead in using...
In terms of smelting process and equipment for molten steel of steel castings, developed countries usually adopt relatively advanced process and equipment, such as high-power electric arc furnace, vacuum furnace and refining furnace (LF furnace, VOD furnace, etc.), and constantly develop various types of high-performance refractories to reduce the...
