Abstract

Metal tubes are produced in the absence of welding, by boring out a solid bar on a mandrel. This mandrel and the hollow blank left after boring is introduced into a continuous rolling mill. The mandrel is retained during the rolling operation by imposing on it a speed calculated in such a way that its available length is at least equal to that which is strictly necessary for the particular rolling operation. After the blank has been rolled, the mandrel is released in such a way that the mandrel, engaged partly in the rolled blank, stops its travel through the mill. The mandrel is removed from the rolled blank which is subjected to the further-processing stages whilst the mandrel is cooled and is then inspected, lubricated and made ready for boring another solid bar.
