The bimetallic jaw wear-resistant castings were successfully poured by using bimetallic liquid pouring / transformation molding technology. The composite casting […]
The physical and mechanical properties of bimetallic composites are different. Although the two metals maintain their original characteristics, their comprehensive
China has also carried out numerical simulation of casting solidification since 1978. Although it started late, it has also developed
Since the 1960s, forsund, Denmark, first applied the finite difference method to study the numerical simulation of solidification process, which
The basic idea of computer solidification simulation is that firstly, the geometric modeling of casting entity is meshed and discretized
The level of numerical simulation has reached a high level in developed countries, especially in the United States and Europe
Compared with foreign countries, the research on numerical modeling of casting solidification in China started late, but made rapid progress.
The basis of casting process design is the casting forming theory. The casting forming theory studies the mechanical, physical and
Firstly, cast the steel castings of the coupler according to the original casting process design. The main problems exposed are:
Due to the differences in product structure, weight, process equipment of production enterprises, production conditions and process technology level, there
For thousands of years, people have mainly solved engineering problems through trial and error, especially how to produce high-quality castings.
As a material processing technology that has been used for thousands of years, sand casting is the most direct way
