With the vigorous development of China's foundry industry,how to improve the production ef-ficiency of castings and reduce the space occupied by equipment has become an important issue faced by various production enterprises.As a key link to improve production efficiency,the rapid cooling technology after the production of castings is gradually attracting widespread attention in the industry.Rapid cooling not only significantly reduces cooling time and equipment required to cool castings,but also optimizes production processes and increases overall production efficiency.In this paper,the cooling method of castings is analyzed,and the characteristics,working principles and functions of water spray cooling and blowing cooling are analyzed,and the rapid cooling products of air cooling and water cool-ing are developed and designed.
