Influence of the Axial Reduction Conditions on the Variation in the Thickness of a Wheel Rim at the Initial Stage of Rolling

By finite-element simulation of the rolling of a Ø957 mm wheel blank on a horizontal six-roll wheel-rolling mill, it is established that rolling resulting in a 18–20 mm axial reduction of the rim minimizes its thickness variation and prevents an abrupt change in the thickness of the web at the junction between its forged and rolled portions.
