Abstract

PROCESO DE MEJORA DE LA CURVABILIDAD DE TUBOS DE COBRE O ALEACION DE COBRE DUROS QUE COMPRENDE UN TRATAMIENTO TERMICO DE DICHOS TUBOS DUROS CARACTERIZADO EN QUE SE HACE DESFILAR EN CONTINUO TUBOS DUROS EN UN DISPOSITIVO DE CALENTAMIENTO QUE PERMITE LLEVAR EL TUBO A UNA TEMPERATURA DE TRATAMIENTO COMPRENDIDA ENTRE T SUB RM-50 C Y T SUB RM-100 C DURANTE UNA DURACION COMPRENDIDA ENTRE 0,1 Y 10 SEGUNDOS, SIENDO T SUB RM LA TEMPERATURA ( C) A LA QUE LA CURVA DE ABLANDAMIENTO DE DICHO COBRE O ALEACION DE COBRE, QUE DA LA CARGA A LA ROTURA RM EN FUNCION DE LA TEMPERATURA, PRESENTA UN PUNTO DE INFLEXIONPROCESS TO IMPROVE THE CURVABILITY OF HARD COPPER TUBES OR COPPER ALLOY, WHICH INCLUDES A THERMAL TREATMENT OF SUCH HARD TUBES CHARACTERIZED IN WHICH A HARD TUBE IS DEPENDED IN A CONTINUOUS DEVICE TO TAKE A TREAT TO TREAT THE TUBE BETWEEN T SUB RM-50 CYT SUB RM-100 C DURING A DURATION INCLUDED BETWEEN 0.1 AND 10 SECONDS, WITH T SUB RM THE TEMPERATURE (C) AT WHICH THE SOFTENING CURVE OF SUCH COPPER OR COPPER ALLOY, WHICH GIVES THE LOAD TO THE RM BREAKDOWN ACCORDING TO THE TEMPERATURE, PRESENTS A Tipping Point
