Abstract

1449662 Rolling tubes VALLOUREC USINESA TUBES DE LORRAINE-ESCAUT ET VALLOUREC REUNIES 7 Sept 1973 [8 Sept 1972] 42092/73. Heading B3M A seamless metal tube is produced by piercing a solid bar with a mandrel to provide a tube blank surrounding the mandrel, and then rolling the blank, together with the mandrel, in a continuous rolling mill. The speed of the mandrel in the rolling mill is controlled, the mandrel is removed from the blank, it is then cooled and lubricated, and returned to the beginning of the installation for piercing another bar. The mandrel is supplied with a piercing head which can optionally be removed before the continuous rolling mill. Solid bars c are initially heated in a rotary hearth furnace 1 and are pierced in a stand 4 comprising skewed rolls while supported on a mandrel M. The resulting hollow blanks while still supported on the mandrels, are rolled in a continuous mill 12 having, successive stands arranged at 90 degrees to each other. The trailing ends of the mandrels are supported at 13 during rolling so that their speed can be controlled and they can be released after rolling. The mandrels are removed from the tubes E after rolling, and the tubes are cut by saws 18 and delivered to a furnace 19, whereas the mandrels are cooled at 17, lubricated at 21, and re-used in the piercing stand 4.
