Abstract

L'invention concerne la fabrication des tubes sans soudure. Entre un perceur 2 et un train de laminage continu 4 est disposé un élongateur, de préférence du type à deux cylindres obliques. L'élongation effectuée dans le perceur est comprise entre environ 1,3 et environ 2, celle de l'élongateur est comprise entre environ 1,4 et environ 2, et celle du laminoir continu est inférieure ou égale à environ 4. Avantageusement le même mandrin est utilisé dans l'élongation et dans le laminoir continu où il est retenu à vitesse controlée. Application notamment aux tubes de fort diamètre.The invention relates to the manufacture of seamless tubes. Between a piercer 2 and a continuous rolling train 4 is disposed an elongator, preferably of the type with two oblique rolls. The elongation carried out in the piercer is between approximately 1.3 and approximately 2, that of the elongator is between approximately 1.4 and approximately 2, and that of the continuous rolling mill is less than or equal to approximately 4. Advantageously the same mandrel is used in elongation and in continuous rolling mill where it is retained at controlled speed. Application in particular to large diameter tubes.
