STUDIES REGARDING THE OPTIMIZATION OF
WITDRAWING ROLLERS AT VERTICAL CONTINUOUS
CASTING OF STEEL
This paper presents an optimization method for withdrawal rollers to the
withdrawal plant at vertical continuous casting of steel. Optimizing rollers was
achieved by: use of statistical calculations applied to quantities, experimental
measurements obtained directly from the withdrawal of blanks, using
techniques CAD (Computer Aided Design) and CAE (Computer Aided
Engineering) design, modeling and optimization of cylinders; using finite
element method, FEM for static and dynamic simulations, the behavior of
withdrawal-straightening rolls in continuous casting process for determining
stress, elongation and movements that occur in this process. The study is both
experimental and theoretical, and aims to improve the process of withdrawal of
the semi continuous casting with vertical curvilinear wire of steel, using modern
methods of analysis, design and optimization of mechanical drives.
