Abstract

SE PRESENTA UN METODO Y UN APARATO PARA EL LAMINADO CONTINUO EN CALIENTE DE PRODUCTOS FERROSOS ALARGADOS QUE EMPLEA UN BLOQUE DE POSFINALIZACION DE BANCOS DE RODILLOS CORRIENTE ABAJO DE LOS BANCOS FINALIZADORES DEL TREN LAMINADOR. UNOS RECIPIENTES DE AGUA U OTROS DISPOSITIVOS REFRIGERADORES SIMILARES SE ENCUENTRAN INTERPUESTOS PREFERIBLEMENTE ENTRE EL ULTIMO BANCO DE FINALIZACION DEL TREN LAMINADO Y EL BLOQUE DE POSTFINALIZACION INCLUYE AL MENOS DOS BANCOS DE REDUCCION SEGUIDOS POR AL MENOS DOS BANCOS DIMENSIONADORES. LOS BANCOS DE REDUCCION TIENEN UNA SECUENCIA DE PASO OVAL ORES TIENEN UNA SECUENCIA DE PASO REDONDEADO EMPLEAN EMBRAGUES U OTROS MEDIOS EQUIVALENTES EN EL TREN IMPULSOR PARA PERMITIR QUE SE HAGAN CAMBIOS ENTRE LAS RELACIONES DE VELOCIDAD DEL IMPULSO EN EL INTERIOR DEL BANCO DE AL MENOS LOS BANCOS DE REDUCCION, Y TAMBIEN ENTRE ALGUNO O TODOS LOS BANCOS DIMENSIONADORES RESTANTES. SE SUMINISTRA UN PROGRAMA FIJO DE LAMINADO PARA TODOS LOS BANCOS DE LAMINADO DURANTE EL AVANCE DE LOS BANCOS FINALIZADORES. DE ESTA FORMA, EL GRUPO FINALIZADOR RECIBE UNA PRIMERA SECCION DE PROCESAMIENTO QUE TIENE UN AREA Y UNA CONFIGURACION DE SU SECCION DE CORTE SUBSTANCIALMENTE CONSTANTE. LA PRIMERA SECCION DE PROCESAMIENTO PASA A TRAVES DEL GRUPO FINALIZADOR Y EL LAMINADO SE PRODUCE TANTO EN NINGUNO, COMO EN ALGUNO, O COMO EN TODOS LOS BANCOS DE RODILLOS FINALIZADORES, DEPENDIENDO DEL TAMAÑO DEL PRODUCTO FINAL DESEADO. EL PRODUCTO CONTINUA ENTONCES A TRAVES DE LOS RECIPIENTES DE AGUA REFRIGERANTE HASTA EL BLOQUE POSTFINALIZADOR, COMO SEGUNDA SECCION DE PROCESAMIENTO. LAS RELACIONES DE VELOCIDAD DEL IMPULSO DENTRO DEL BANCO DE LOS BANCOS DE RODILLOS EN EL BLOQUE POSTFINALIZADOR SON APROPIADAMENTE AJUSTADAS PARA ACOMODAR EL GIRO DE LOS RODILLOS DE LA SEGUNDA SECCION DE PROCESAMIENTO. LAS REDUCCIONES TOTALES EFECTUADAS EN LOS BANCOS DE REDUCCION INICIALES DEL BLOQUE POSTFINALIZADOR ESTAN SOBRE EL 14%, MEDIANTE LO CUAL SE PRODUCE UN NIVEL INCREMENTADO DE ENERGIA EN EL PRODUCTO SUFICIENTEPARA CREAR UNA DISTRIBUCION SUBSTANCIALMENTE UNIFORME DE LOS GRANOS FINOS. TIPICAMENTE, ESTAS REDUCCIONES TOTALES INICIALES, SERAN DEL ORDEN DE 20-50%. REDUCCIONES SIGNIFICATIVAMENTE MAS LIGERAS DEL ORDEN DE 2-15% TIENEN LUGAR EN LAS SECUENCIAS DE PASO REDONDEADO DOR PARA OBTENER LAS DESEADAS TOLERANCIAS CERRADAS DE DIMENSINAMIENTO EN EL PRODUCTO ACABADO. EL INTERVALO DE TIEMPO ENTRE LA REDUCCION MAYOR EFECTUADA EN LA FRECUENCIA DE PASO OVAL ONDEADO Y LAS REDUCCIONES MAS LIGERAS QUE SE EFECTUAN DURANTE EL DIMENSIONAMIENTO EN LA SECUENCIA DE PASO REDONDEADO REDONDEADO ES TAL QUE EL TAMAÑO DEL GRANO RESULTANTE A LO LARGO DE LA SECCION DE CORTE DEL PRODUCTO NO VARIARA EN MAS DE 2, Y EN LA MAYOR PARTE DE LOS CASOS EN MENOS DE 1 (NUMERO DE TAMAÑO DE GRANO ASTM).
