[0002] In the production of lithium battery diaphragm industry, the thickness of the diaphragm is one of the important physical property indicators. The molten polymer material flows out after the thickness is controlled by the opening of the die outlet, and adheres to the cold roller under its own weight. Through the cooling effect of the cold roller, the initial thick sheet is formed. This process is called casting. The cooling effect of the thick sheet on the cold roller is one of the important factors that determine the quality of the casting, and the quality of the casting will affect the physical, mechanical, electrical and other properties of the subsequent stretch-formed film, as well as the product yield. Therefore, ensuring the quality of the casting is a key step in producing high-quality films.

With the increase in production line speed, the diameter of the cold roller is getting larger and larger, resulting in increased processing and procurement costs. Since the thick film castings are thicker and the speed is higher in the production process, it is difficult to obtain thick films of good quality through the existing casting cooling methods.
