Laboratory and mathematical simulation of slab edging
Original language description
The combination of the above processes is often described as vertical-horizontal (V-H) rolling. This paper presents a comparison between results of laboratory slab edging in vertical stand and the results of mathematical modelling using the finite-element method. The paper provides a detailed description of digitization of the slab cross-section shape upon laboratory rolling and solutions to problems with determining its geometrical centre and aligning with the system of coordinates. Inverse analysis principles were employed for finding the basic initial and boundary conditions and simulation parameters (mesh density, maximum and minimum time increment) in order to achieve an optimum agreement between the resulting shape and the outcome of the laboratory rolling and between calculated and measured rolling forces. The most important factors affecting the metal flow in the roll gap include the friction, flow stress and temperature field homogeneity.
