Development status of casting technology in China

Compared with foreign countries, the research on numerical modeling of casting solidification in China started late, but made rapid progress. In the late 1970s, Shenyang Foundry Research Institute, Dalian University of technology and Tsinghua University successively carried out the research on Foundry digitization. In terms of mathematical and physical...

Development status of casting technology

The basis of casting process design is the casting forming theory. The casting forming theory studies the mechanical, physical and chemical changes of metal in the process of transformation from liquid to liquid and solid mixed state and then to solid state. These changes occur in the mold cavity....

Development of casting simulation technology

For thousands of years, people have mainly solved engineering problems through trial and error, especially how to produce high-quality castings. Because casting includes smelting, molding, pouring and post-treatment processes, each process requires professional knowledge and technology, but most factories complete all processes alone. Since the 20th century, scientific research...

Casting technology of locking block for heavy lathe

At present, the production of heavy-duty lathe locking block has the advantages of low yield, high cost, complex on-site operation process, shrinkage and porosity defects. Based on this situation, the process needs to be improved. The locking block is a thick wall casting, with a wall thickness of 260mm,...
