Calculation of the deformational energy during slab-width rolling

This paper focuses on an automatic calculation of the deformational energy consumed for slab-width rolling. For the calculation of the deformational energy consumed during 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 accelerations of the unloaded edger using the velocity as an input signal. The existing measurement of electrical power and the model-estimated power of the unloaded edger make it possible to estimate the power consumed for the slab-width rolling only. The integration of the power over every pass through the edger yields the deformational energy.
