Abstract

LA INVENCION SE REFIERE A UN PROCESO DE LAMINADO DE UN PRODUCTO PLANO (5) POR PASADAS SUCESIVAS EN UN LAMINADOR REVERSIBLE, ALTERNATIVAMENTE EN UN SENTIDO Y EN OTRO. SEGUN LA INVENCION, EL PRODUCTO (5) QUE TIENE UN ESPESOR BRUTO (E SUB 0) SENSIBLEMENTE UNIFORME, SE DA A LOS CILINDROS (2, 2''), PARA LA PRIMERA PASADA DE ARRANQUE (P SUB 1), UN DESVIO (E SUB 1) INFERIOR A (E SUB 0) QUE DETERMINA UN ANGULO DE ATAQUE (A SUB 1) SUFICIENTEMENTE REDUCIDO PARA EVITAR UN RECHAZO DE ENTRADA Y SE DISMINUYE, A LO LARGO DE ESTA PRIMERA PASADA (P SUB 1), EL DESVIO DE LOS CILINDROS (2, 2'') HASTA UN VALOR (E SUB 2) DE TAL MANERA QUE LA REDUCCION TOTAL DE ESPESOR (E SUB 0-E SUB 2) PERMANECE COMPATIBLE CON LA POTENCIA Y LA FUERZA MAXIMAS DEL LAMINADOR, Y DESPUES, PARA LA SEGUNDA PASADA (P SUB 2), SE DA A LOS CILINDROS DE TRABAJO (2, 2'') UN DESVIO (E SUB 3) DE MANERA QUE EL ANGULO DE ATAQUE (A SUB 2) SEA BASTANTE REDUCIDO PARA EVITAR UN RECHAZO DE ENTRADA Y SE DISMINUYE, DURANTE ESTA SEGUNDA PASADA (P SUB 2), EL DESVIO DE LOS CILINDROS HASTA UN VALOR (E SUB 4) COMPATIBLE CON LA POTENCIA Y LA FUERZA MAXIMAS DEL LAMINADOR Y ASI SUCESIVAMENTE. LA INVENCION SE APLICA ESPECIALMENTE AL LAMINADO DE CHAPAS METALICAS.THE INVENTION REFERS TO A PROCESS OF LAMINATING A FLAT PRODUCT (5) BY SUCCESSIVE PASSES IN A REVERSIBLE LAMINATOR, ALTERNATIVELY IN ONE DIRECTION AND IN ANOTHER. ACCORDING TO THE INVENTION, THE PRODUCT (5) THAT HAS A GROSS THICKNESS (E SUB 0) SENSITIVELY UNIFORM, IS GIVEN TO THE CYLINDERS (2, 2``), FOR THE FIRST STARTING PASS (P SUB 1), A DEVIATION ( E SUB 1) LESS THAN (E SUB 0) THAT DETERMINES AN ANGLE OF ATTACK (A SUB 1) SUFFICIENTLY REDUCED TO AVOID REJECTION OF ENTRY AND DECREASE, DURING THIS FIRST PASS (P SUB 1), THE DEVIATION OF THE CYLINDERS (2, 2``) UP TO A VALUE (E SUB 2) SO THAT THE TOTAL THICKNESS REDUCTION (E SUB 0-E SUB 2) REMAINS COMPATIBLE WITH THE MAXIMUM POWER AND STRENGTH OF THE LAMINATOR, AND THEN, FOR THE SECOND PASS (P SUB 2), THE WORKING CYLINDERS (2, 2 '') ARE GIVEN A DEVIATION (E SUB 3) SO THAT THE ANGLE OF ATTACK (A SUB 2) IS ENOUGH REDUCED TO AVOID A REJECTION OF ENTRY AND DECREASES, DURING THIS SECOND PASS (P SUB 2), THE DEVIATION OF THE CYLINDERS UP TO A VALUE (E SUB 4) COMPATIBLE WITH THE MAXIMUM POWER AND STRENGTH OF THE LAMINATOR AND SO ON. THE INVENTION APPLIES ESPECIALLY TO THE LAMINATE OF METAL SHEETS.
