Abstract

PURPOSE: To make excellent the dimensional accuracy of the product, by installing the mandrel transferrer for restraining the mandrel while the rolling work at a desired speed, in the inlet side of the mandrel mill.
CONSTITUTION: The mandrel is inserted into the pipe and is rolled on ths skid 10 so as to embark on the roller table 3. The rear end of the mandrel is caught by the pawls 11 of the thrust block before starting the rolling of the front end of the pipe, and the mandrel is sent into the rolling mill at the specified speed; during the rolling work, the mandrel speed is controlled. The pawls 11 of the thrust block are opened or closed by rotating pinions 15 with movement of the rack 13 owing to the cylinder 12. When the rear end of the pipe passes over the stand of the third from the inlet side, the pawls 11 catching the rear end of the mandrel are opened to the position 11' by the cylinder 12, in order to release the mandrel and also to retreat the thrust block.
