Abstract

METODO DE LAMINACION A ALTA VELOCIDAD DE APROXIMADAMENTE 120 A 140 METROS POR SEGUNDO Y MAS, PARA MATERIAL LAMINADO QUE TIENE UNA SECCION CIRCULAR Y UN DIAMETRO DE 5,5 A 6,5/7 MM O SU EQUIVALENTE LLEVANDOSE A CABO LA LAMINACION A ALTA VELOCIDAD POR UN SISTEMA QUE COMPRENDE POR LO MENOS UN CONJUNTO DE LAMINACION 11 Y UN CABEZAL 12 FORMADOR DE ROLLOS; CONJUNTO DE LAMINACION 11 QUE INCLUYE UNA PLURALIDAD DE PARES DE RODILLOS CON SUS EJES COLOCADOS ALTERNATIVAMENTE A APROXIMADAMENTE 90 (GRADOS) ENTRE SI, ESTANDO LAS VELOCIDADES DE LOS PARES DE RODILLOS ESTRICTAMENTE CORRELACIONADAS Y CONTROLADAS DISPONIENDOSE EL SISTEMA PREVIAMENTE, ANTES DE LA LLEGADA DEL MATERIAL LAMINADO, PARA UNA VELOCIDAD DE LAMINACION ENTRE 40 Y UNOS 100 METROS POR SEGUNDO Y VENTAJOSAMENTE ENTRE 60 Y 80 METROS POR SEGUNDO, MANTENIENDOSE ESTA VELOCIDAD DE LAMINACION POR LO MENOS HASTA QUE EL EXTREMO DELANTERO DEL MATERIAL LAMINADO HAYA ENTRADO EN EL CABEZAL L2 FORMADOR DEL ROLLO DESPUES DE LO CUAL EN POR LO MENOS UNA ELEVACION DEL INCREMENTO SE LLEVA LA VELOCIDAD DE LAMINACION A 120 A 140 METROS POR SEGUNDO Y SE MANTIENE EN ESTE NIVEL DURANTE TODO EL PERIODO DE LAMINACION DE LA SECCION ESPECIFICA, REDUCIENDOSE LA VELOCIDAD A LA PRIMERA VELOCIDAD DE ARRANQUE EN EL MOMENTO TRANSITORIO DE LLEGADA DE LA SIGUIENTE SECCION ESPECIFICA. SISTEMA PARA LA LAMINACION A ALTA VELOCIDAD DE SECCIONES CIRCULARES QUE TIENEN UN DIAMETRO DE 5,5 A 6,5/ MM, O SU EQUIVALENTE, A 120 A 140 METROS POR SEGUNDO O MAS, SEGUN EL METODO ANTERIOR, LLEVANDOSE A CABO LA LAMINACION A ALTA VELOCIDAD CON UN SISTEMA QUE COMPRENDE POR LO MENOS UN CONJUNTO LAMINADOR 11 Y UN CABEZAL 12 FORMADOR DEL ROLLO, CONJUNTO DE LAMINACION 11 QUE INCLUYE UNA PLURALIDAD DE PARES DE RODILLOS CON SUS EJES SITUADOS ALTERNATIVAMENTE A APROXIMADAMENTE 90 (GRADOS) ENTRE SI, ESTANDO LAS VELOCIDADES DE LOS PARES DE RODILLOS ESTRICTAMENTE CORRELACIONADAS Y CONTROLADAS, EN CUYO SISTEMA LOS MOTORES SON REGULADOS, CONTROLADOS Y ACCIONADOS POR UN SISTEMA DE CONTROL Y ACCIONAMIENTO 22 QUE COMPRENDE SENSORES Y MONITORES PARA EJECUTAR EL CONTROL Y LA COMPROBACION Y QUE COMIENZA LA LAMINACION A BAJA VELOCIDAD Y, CUANDO EL MATERIAL LAMINADO HA ENTRADO EN EL CABEZAL 12 FORMADOR DEL ROLLO, ELEVA LA VELOCIDAD DE ENROLLAMIENTO A LA VELOCIDAD MAXIMA.
