Abstract

PROCEDIMENTO DE METALISTERIA, CONCRETAMENTE PARA OBTENER TRAMOS DE TUBOS DE DISTINTOS TAMAÑOS PARA VARIOS USOS, HECHOS DE ACERO CON UN CONTENIDO DE CARBONO DE ENTRE EL 0,10% Y EL 0,50% CON TOLERANCIAS REDUCIDAS. EL PROCEDIMIENTO CONLLEVA LA PROVISION, COMO MATERIAL INICIAL, DE UNA BARRA REDONDA DE ACERO LAMINADO EN CALIENTE QUE SE PREPARA Y SE CORTA PARA OBTENER AL MENOS UN BLOQUE (15) QUE SE PERFORA Y SE SOMETE A TRATAMIENTO QUIMICO. SE PRESIONA EL BLOQUE (15) Y SE LE SOMETE OPTATIVAMENTE A UN TRATAMIENTO FINAL DE VOLTEO Y CALOR PARA OBTENER EL PRODUCTO ACABADO (15A), COMO UN CILINDRO HIDRAULICO O OELODINAMICO O UNA FUNDA PARA FILTROS DE LATA PRESION O UN TUBO PARA ALTAS PRESIONES, O UN MANGUITO, UTILIZANDO UNA CANTIDAD DE ACERO REDUCIDA.
