Background

The precoated sand is used for complex castings with higher requirements on dimensional accuracy, and is one of the best molding materials for automobiles, tractors, hydraulic parts and the like. Along with the development of the machinery industry, especially the automobile industry, at home and abroad, the requirement on the quality of castings is higher and higher, and the application of the precoated sand is wider and wider. With the rapid development of technology, highly automated casting lines are used in large quantities, which is a major measure for mass casting to improve productivity. However, the short cycle time of the molding sand and the high temperature of the sand have a great influence on the performance of the molding sand, the production order and the quality of the cast product, which has resulted in the so-called hot sand problem. The higher the automation degree of the moulding line, the faster the circulation of sand, and the more serious the hot sand problem will be. Therefore, the temperature of the circulating sand must be effectively controlled on a casting production line to ensure the quality of the castings.

The boiling cooling bed is a cooling device which is most used and has the widest application range in a mold casting sand treatment system. The boiling cooling bed mainly comprises an air box, a boiling box, a diffusion box, a blast system and an exhaust system.
