Abstract

Forno a longheroni refrattari con caricamento centrale per riscaldo ed accumulo di prodotti caldi in cui la carica centrale proviene da una colata continua, o da precedenti lavorazioni a caldo, mentre un lato del forno (10) serve per l'introduzione della carica fredda (12) e l'altro lato per l'evacuazione della carica riscaldata (15), il canale di guida (22) centrale essendo definito da una pluralità di longheroni fissi (23) cooperanti con una pluralità di longheroni mobili (24, 24a, 24b) sostanzialmente affacciati in posizione alta, essendo la larghezza di detto canale di guida (22) ed eventualmente la posizione alta di detti longheroni mobili (24) funzione della sezione del prodotto caldo (26) entrante.
