Abstract

PROCEDIMIENTO DE LAMINADO EN CALIENTE PARA LA FABRICACION DE TUBOS METALICOS SIN SOLDADURA.SE CONTROLA EL MOVIMIENTO DEL MANDRIL DURANTE TODO MOMENTO EN QUE LA PIEZA SEMIACABADA ESTA COGIDA EN CUALQUIER JAULA DE LAMINACION, MOVIENDO PARA ELLO EL MANDRIL AXIALMENTE EN LA MISMA DIRECCION QUE LA PIEZA SEMIACABADA A UNA VELOCIDAD CONSTANTE, DE MODO QUE EL MANDRIL ESTA PRESENTE Y ES CONTROLADO EN CADA JAULA DE LAMINACION, EN EL MOMENTO EN QUE EL EXTREMO DELANTERO DE LA PIEZA SEMIACABADA LLEGA A CADA JAULA. LA VELOCIDAD DEL MANDRIL SE MANTIENE CONSTANTE HASTA QUELA PIEZA SEMIACABADA ABANDONA LA JAULA DE LAMINACION DE SALIDA.
