The Finite Element Analysis of the Stress Field in the Core of Continuous Casting Slab

The continuous caseter was widely used of in steelmaking enterprises, with the improvement of product quality, the optimization of the cost control and the improvement of production efficiency, the process requirements in production the was continuously improved and updated. The velocity of cooling water was taken as a variable to conduct the numerical simulation analyze of the entire model. 6m/s, 8m/s, 10m/s, 12m/s, 14m/s were set as velocity of cooling water respectively, and then used the finite element method to analysis the stress of the core of the slab. In the stress field analysis, when the cooling water speed was up to 10m/s, the decline of billet stress was the most notable, which decreased 50MPa. When the velocity water was other value, the stress decreased as well, but the decreased was slight. So that set the crystallizer cold water speed as 10m/s was the optimal decision, which effectively supported the continuous casting production with theory.
