Abstract

Une structure de moulage et un procédé de fabrication de tuyaux qui sont capables d'exécuter un processus de moulage par une opération de moulage en continu par des rouleaux utilisant des rouleaux bi-fonction convenablement utilisés pour des tuyaux d'acier d'une pluralité de tailles. Une structure de moulage et un procédé de fabrication de tuyaux dans lesquels la structure de moulage de tuyaux comprend un poste de défonçage, un poste de regroupement ou un poste de rouleau-cage et un poste de galets de guidage, caractérisés en ce qu'une courbe dont l'incurvation varie en continu ou au pas à pas est utilisée en tant que calibre à galets pour mouler en courbe les tuyaux en une forme sensiblement semi-circulaire ou sensiblement en une forme de produits finis par une pluralité d'étages de galets supérieurs et inférieurs du poste de défonçage avec un laminoir à galets de guidage sans fournir de rouleau-cage.
