Abstract

EL ACERO UTILIZADO PARA LA FABRICACION DEL TUBO CONTIENE AL MENOS 0,3% DE CARBONO Y ELEMENTOS DE ALEACION TALES COMO EL CROMO Y EL MOLIBDENO EN CANTIDAD SUFICIENTE PARA QUE EL DESBASTE DEL TUBO PRESENTE UNA ESTRUCTURA BAINITICA TRAS LA FORMACION EN CALIENTE Y ENFRIAMIENTO NATURAL ASI COMO ELEMENTOS CARBURIGENOS TALES COMO EL NIOBIO Y EL VANADIO. SE REALIZA SUCESIVAMENTE, EL CALENTAMIENTO DE UN TRAMO DE BARRA PLENA DE ACERO A UNA TEMPERATURA DE PUESTA EN SOLUCION DE LOS ELEMENTOS CARBURIGENOS, LA FORMACION EN CALIENTE DE UN DESBASTE TUBULAR, EL ENFRIAMIENTO EN EL AIRE, EL ESTIRADO EN FRIO DEL DESBASTE Y EL MARTILLEO O EL LAMINADO EN FRIO DEL TUBO OBTENIDO. LA INVENCION PERMITE OBTENER MARCOS T HORQUILLAS DE CICLO MAS LIGEROS A CON RESISTENCIA MECANICA SUPERIOR.
