Abstract
Procedimento di prelaminazione controllata per bramme sottili (20) uscenti da colata continua in cui prelaminazione è effettuata con una pluralità di coppie di rulli (14-16) raggruppate in uno o più gruppi di prelaminazione (10) essendo posto subito a valle dei rulli al piede (12) della lingottiera (11), in dette coppie di rulli (14-16) essendo presente almeno un rullo mobile (16), dette coppie di rulli (14-16) essendo associate a mezzi di precisione (18) ed a mezzi a capsula idraulica (17), essendo presenti mezzi a trasduttore di posizione (24), essendo detti mezzi a trasduzione di precisione (18) e di posizione (24) associati a mezzi di elaborazione (21), almeno la prima di dette coppie di rulli (14-16) lavorando sulla bramma (20) appena uscita dalla lingotteria (11) e con un esile pellesolidificata, il gruppo di elaborazione (21) essendo ulteriormente associato sia a mezzi rilevatori di temperatura a bagno liquido(25a) in maniera, che a mezzi rilevatori di velocità di colata (26) e a mezzi rilevatori di temperatura (25b) della bramma (20), sia uscente dalla lingotteria (11) che all'interno del gruppo di prelaminazione (10) e, in base ad un programma di asservimento e controllo, condizionando la posizione reciproca dei rulli (16) di almeno parte delle coppie di rulli (14-16) per ottenere una prelaminazione con riduzione dello spessore della bramma (20) uscente dall'ultima coppia di rulli di prelaminazione (14-16) di almeno 10% tale da annullare il cuore liquido e da portare a contatto le zone bifasiche, si che la struttura di solidificazione centrale risulti affinata e la segregazione centrale venga minimizzata.Dispositivo idoneo ad eseguire la preliminazione controllata di bramme sottili secondo il procedimento di cui sopra, presentante mezzi rilevatori di temperatura bagno liquido (25a) in maniera mezzi rilevatori di temperatura (25b) bramma (20), mezzi rilevatori velocità bramma (26), mezzi rilevatori presenza cono liquido(28).Controlled pre-lamination process for thin slabs (20) coming out of continuous casting in which pre-lamination is carried out with a plurality of pairs of rollers (14-16) grouped in one or more pre-lamination groups (10) being placed immediately downstream of the rollers at the foot (12) of the ingot mold (11), in said pairs of rollers (14-16) being present at least one mobile roller (16), said pairs of rollers (14-16) being associated with precision means (18) and hydraulic capsule means (17), with position transducer means (24) being present, said precision (18) and position transducer means (24) associated with processing means (21), at least the first of said pairs of rollers (14-16) working on the slab (20) just out of the ingot mold (11) and with a thin solidified skin, the processing group (21) being further associated both with liquid bath temperature detecting means (25a) in a , which at casting speed detecting means (26 ) and to temperature detecting means (25b) of the slab (20), both leaving the ingot mold (11) and inside the pre-lamination group (10) and, on the basis of a slave and control program, conditioning the mutual position of the rollers (16) of at least part of the pairs of rollers (14-16) to obtain a pre-lamination with a reduction in the thickness of the slab (20) leaving the last pair of pre-lamination rollers (14-16) by at least 10% such as to cancel the liquid heart and to bring the biphasic areas into contact, so that the central solidification structure is refined and the central segregation is minimized. liquid bath (25a) in the manner of temperature detecting means (25b) slab (20), slab speed detecting means (26), liquid cone presence detecting means (28).
