Abstract

Esta solicitud se refiere a una instalación 10 para la laminación de un tubo sin costura. La instalación comprende un perforador giratorio 20 capaz de perforar una palanquilla 11 contra una punta 22 montada sobre una palanca de modo de obtener un tubo perforado 12. La palanca está conectada a un freno 26 capaz de contrarrestar el impulso axial que se genera sobre la palanca durante la perforación. La instalación comprende también un laminador longitudinal 30 capaz de laminar el tubo perforado 12 sobre un mandril 32 para obtener un tubo semielaborado 13. El mandril está conectado a un freno de mantenimiento 34 capaz de imprimir al mandril una velocidad predeterminada durante la laminación. En la instalación según la presente el freno 26 y el freno de mantenimiento 34 se logran mediante un único freno de impulso-mantenimiento 36. La presente también hace referencia a un método para la laminación de un tubo sin costura.This application refers to an installation 10 for rolling a seamless tube. The installation comprises a rotary perforator 20 capable of drilling a billet 11 against a tip 22 mounted on a lever so as to obtain a perforated tube 12. The lever is connected to a brake 26 capable of counteracting the axial impulse generated on the lever during drilling The installation also comprises a longitudinal laminator 30 capable of laminating the perforated tube 12 on a mandrel 32 to obtain a semi-finished tube 13. The mandrel is connected to a maintenance brake 34 capable of printing to the mandrel a predetermined speed during lamination. In the installation according to the present the brake 26 and the maintenance brake 34 are achieved by a single impulse-maintenance brake 36. The present also refers to a method for rolling a seamless tube.
