Development prospect of casting simulation technology
Since the 21st century, solidification numerical simulation technology has been developing continuously, and it is in the stage of optimization design. The numerical analysis of flow field and temperature field in the process of filling and solidification of axle housing has been developed more mature, and the casting simulation...

Present situation of casting technology at China and abroad
In foreign countries, the analysis unit of “heat and mass flow analyzer” of Columbia University was first used in casting simulation technology. Prosenjit Das et al. Used regression analysis method and Taguchi method to optimize the process of ordinary sand mold casting of aluminum alloy materials, and obtained the...

Sand mold casting technology of tractor axle housing
A certain type of broken axle housing of a company is mainly used for tractor load-bearing bridge, with an annual output of 10000 sets. The service conditions of the axle housing include plateau, saline alkali, desert and other terrain and latitude. Under full load condition, it must bear high...

Casting technology of lost foam casting shell
The shell casting process of lost foam casting has cleaned the foam thoroughly and thoroughly through the roasting process before pouring liquid metal. Therefore, it thoroughly eliminated the unfriendly influence and trouble caused by the foam mold in the liquid metal forming process. Very careful, always on tenterhooks, the...

Study on the casting technology of nodular cast iron into cylinder
According to the analysis of the casting structure and key casting technology difficulties of the intake cylinder, this paper mainly focuses on the theoretical research, design and calculation of the core casting technology scheme and process of the intake cylinder, and determines the final optimization process technology scheme. In...

Feeding theory and technology of cylinder body cast iron
As one of the key parts of the engine, the cast iron parts of the engine block have high quality requirements, and the structure of the cylinder block is more complex than that of the general castings, so it is difficult to produce, and a large number of core...
