Abstract

Disclosed is a skew rolling assembly suitable for large-size superalloy bars, including four rollers with completely identical shape and size, where the four rollers are all active rollers. In the production process, the four rollers play a role in promoting the forward flow of blank metal in a rolling direction, thus avoiding a rolling jamming phenomenon caused by the obstruction of guide plates to the forward flow of the blank in the rolling process of the prior art. The providing of the four rollers improves the rolling speed and increases the degree of deformation. Disclosed is a skew rolling method suitable for large-size superalloy bars. By utilizing the skew rolling assembly suitable for the large-size superalloy bars, and utilizing four rotating active rollers for the skew-rolling forming of bars, the rolling speed is improved, the problem that the cooperative rolling of two rollers and guide plates in the prior art is prone to the phenomenon of rolling jamming is avoided, the forming quality is guaranteed, the rolling production efficiency is improved, and the degree of deformation is increased.
