With the rapid development of the national economy, the foundry industry as the basic equipment has also developed rapidly, and the output of various wear-resistant castings is continuously increasing. At present, the acceleration of world economic globalization provides opportunities for the development of China's foundry industry, and the demand for castings keeps increasing. However, at present, there are still many problems in China's castings, such as poor comprehensive quality of castings, poor working conditions, low productivity of manufacturers, ineffective improvement of casting technology and economic benefits, which seriously restrict the development of foundry industry.

Therefore, it is imperative for the development of foundry industry to grasp the technological improvement of foundry industry in China and strive to improve the internal and external quality of castings, which is also the foundation of the evergreen development of foundry industry.
