Abstract
PARA FABRICAR UNA BANDA DE ACERO 12 DE DESBASTE CON MATERIAL 4 YA FUNDIDO, PRIMERO SE SEPARAN LAS PARTES 4A,4B DE LA MISMA LONGITUD (3) DE LO OBTENIDO DE LA FUNDICION SECA. A CONTINUACION ESTAS PARTES SE INTRODUCEN UNA DETRAS DE OTRA EN EL HORNO 5, DONDE SON MANTENIDASA UNA TEMPERATURA DE LAMINADO. MAS TARDE ESTAS PARTES 4A,4B PASAN UNA DETRAS DE OTRA A TEMPERATURA DE LAMINADO EN EL LAMINADOR 9. ESTA PREVISTO QUE LAS PARTES 4A,4B PASEN ENTONCES ESTIRADAS AL HORNO 5, DEJANDOLAS ALLI HASTA EL LAMINADO. HASTA EL COMIENZO DEL LAMINADO EN SI SE PREPARAN UNA SERIE DE ESTAS PARTES Y SE ALMACENAN LA FUNDICION CONTINUA SIGUE DURANTE EL LAMINADO Y LAS PARTES 4A,4B FORMADAS PASAN AL HORNO 5 Y SE DEJAN HASTA EL LAMINADO. LOS TIEMPOS DE MONTAJE EN EL LAMINADOR 9 SE SELECCIONAN EN LAS PAUSAS DE LOS CICLOS DE LAMINADO, LAS PARTES 4B QUE SE ESTAN FORMANDO ENTRETANTO PASAN AL HORNO 5, DONDE QUEDAN ALMACENADAS (15).
