Abstract

PROCEDIMIENTO DE ELABORACION DE CABLES Y VARILLAS DE ACERO POR ESTIRADO EN FRIO.CONSISTENTE EN ESTIRAR ACERO CON BAJO CONTENIDO EN CARBONO QUE POSEE UNA MICROESTRUCTURA DOBLE CONSISTENTE EN UNA FASE FUERTE DISPERSA EN UNA MATRIZ DE FERRITA BLANDA. ESTRUCTURAS PREFERIDAS SON LAS QUE INCLUYEN COMO FASE FUERTE FERRITA-MARTENSITA O FERRITA-BAINITA. EL ACERO DE PARTIDA TIENE LA SIGUIENTE COMPOSICION: 0,05/0,15 C; 1/3 SI; Y, EVENTUALMENTE, 0,05/0,15 V. ESTE ACERO SE TRATA TERMICAMENTE HASTA CONSEGUIR LA DOBLE MICROESTRUCTURA INDICADA Y LUEGO SE ESTIRA EN PASADAS MULTIPLES, SIN RECOCIDOS INTERMEDIOS, CON UNA REDUCCION TOTAL DE SECCION DE HASTA 99,9, OBTENIENDOSE RESISTENCIAS A LA TRACCION USUALES ENTRE 827 MPA Y 2687 MPA, PUDIENDOSE SUPERAR 2756 MPA.PROCEDURE FOR THE ELABORATION OF STEEL CABLES AND RODS BY COLD DRAWING. CONSISTENT IN STRETCHING STEEL WITH LOW CARBON CONTENT THAT HAS A DOUBLE MICROSTRUCTURE CONSISTENT OF A STRONG PHASE DISPERSED IN A SOFT FERRITE MATRIX. PREFERRED STRUCTURES ARE THOSE THAT INCLUDE AS STRONG PHASE FERRITE-MARTENSITE OR FERRITE-BAINITE. THE STARTING STEEL HAS THE FOLLOWING COMPOSITION: 0.05 / 0.15 C; 1/3 YES; AND EVENTUALLY, 0.05 / 0.15 V. THIS STEEL IS THERMICALLY TREATED UNTIL THE INDICATED DOUBLE MICROSTRUCTURE IS REQUIRED AND THEN IT IS STRETCHED IN MULTIPLE PASSES, WITHOUT INTERMEDIATE ANNEALING, WITH A TOTAL REDUCTION OF SECTION OF UP TO 99.9, RESISTING AT THE USUAL TRACTION BETWEEN 827 MPA AND 2687 MPA, IT CAN BE EXCEEDED 2756 MPA.
