<p>1. Hollow billet outlet for a skew-rolling mill consisting of driven rollers (1) which are arranged at a distance from each other over the length of the outlet, are tilted with respect to the outlet longitudinal axis (2) and which receive the hollow billets, characterised in that the rollers (1) are arranged in pairs and in each case have an upper roller and a lower roller lying opposite, whereby the tilting of the lower rollers on the one hand and the tilting of the upper rollers on the other hand is equal but inverse, in that the rollers have a hyperbolic profile and are adjustable in their tilting and their rotational speed and in that between the rollers covers (3) are provided which prevent heat radiation from the hollow billet.</p> |
