  • Determination of the deformational energy during slab-width rolling on an edger mill = Določanje deformacijske energije pri valjanju slabov na krčilnem ogrodju
    Vode, Franci ...
    The production of hot-rolling strips of known dimensions requires planning of the slab dimensions and the dimension-change traction of slabs along the production line. A combination of an edger-roll ... gap measurement and the deformational energy consumed to achieve the desired slab width on the edger enable a rough estimation of the slab widths during rolling. The paper is focused on an automatic calculation of the deformational energy consumed for slab-width rolling on the basis of existing edger measurements. For the calculation of the deformational energy consumed for slab-width rolling a mathematical model of an unloaded edger was built. The edger roller was treated as a stiff, rotary-driven body. The model calculates the consumed power for the velocity changes of the unloaded edger using the velocity input signal. The constructed model has enabled an estimation of the power consumed for the slab-width rolling only. The integration of the power over every pass through the edger yields the deformational energy. The acquired information is instantly written in a database, where they can be accessible for an estimation of the slab width during rolling.
