In this work is presented an optimization solution of correcting withdrawal rollers to the withdrawal of the semifinished products of steel to vertical continuous casting plant of steel for increase the productivity of continuous casting process. To optimize rollers was used statistical calculations applied to experimental measurements obtained directly from the withdrawal of blanks and using modern techniques, such as: CAD (Computer Aided Design) and CAE (Computer Aided Engineering) for design, modeling and optimization of rollers. Also, has been used finite element method (FEM) for static and dynamic simulations, the behavior of withdrawal-straightening rolls in continuous casting process for determining stress, strain and displacement that occur in this process concerning the semi-finished products withdrawn. The studies aim to improve the process of withdrawal of the semi continuous castings with vertical curvilinear wire of steel for improve the quality of semi-finished products.
