Abstract
For steel billets cooling after the continuous casting process, structures calls steel mill bags are used for store the billets. The billets are stacked on XX to YY sets up billets. These bags are to enable the slow cooling of the billets and thus improve the metallurgical quality of the material. The study aimed to create a computational tool able to simulate the cooling profile of these billets, helping in decision making in the industrial environment. The model allows simulation of various load situations, various sizes and types of billets. Results were validated with the numerical model developed by SILVA , which had been validated with experimental tests. The difference for the existing model was approximately 2%, which validates the results and let the tool able to be used in the industrial environment. The model allowed better planning of production, representing a potential gain of 12 hours in 72 hours of production
