Abstract

Production of a hollow block (1) made from metallic material, especially roller bearing steel comprises deforming a cylindrically deformed starting material (2) in a cross rolling mill (3, 4) using an axially fixed mandrel (5) to form a tubular hollow block. The starting material is made from a pre-deformed material produced by direct continuous casting, in which the starting material is not pre-rolled before being introduced into the cross rolling mill.
