Computational modelling of effects of roll gap geometry in hot rolling

The effects of initial slab thickness, reduction, roll diameter, and speed on the rolling load, torque, temperature distribution in the stock, and redundant shear strain have been computed for rolling of Kh18N9T stainless steel. Two new concepts – the ‘net shear angle’ and the ‘average shear strain’ of a rolling pass have been introduced to quantify the degree of inhomogeneity in deformation. Finally, the results are compared with those of similar rolling theories.
