Research status of casting simulation in China

Casting belongs to liquid metal forming technology. In actual production, casting engineers often make process according to previous experience, and lack of scientific and rigorous judgment on flow field, temperature field and defect location and size. However, casting defects often exist in the body, which is difficult to find...
