ABSTRACT:
Pre-reduction equipment for guiding a pipe blank and reducing its end before it enters an "Assel" rolling mill, which is disposed immediately downstream from the pre-reduction equipment and consists of several freely rotatable rollers, which are disposed uniformly distributed about the pipe blank and can be set concentrically against the pipe blank and the setting motion of which can be controlled as a function of the determined position of the pipe blank. In order to make it reliably possible to initially roll particularly short pipe blanks with simple means, it is proposed that, for the initial rolling of short pipe blanks, the blanks are introduced into the "Assel" rolling mill by moving the pre-reduction equipment with the rollers clamping the pipe blank and, during the initial rolling in the "Assel" rolling mill, can be rotatably guided in lunette fashion by the rollers of the pre-reduction equipment.
