Zusammenfassung:	CET APPAREIL COMPREND DEUX TAMBOURS REFROIDISSEURS CONTRAROTATIFS 14 DANS UN CAISSON 13 ET AU MOINS UN ECHANGEUR DE CHALEUR 21 PRODUISANT DE LA VAPEUR, PAR EXEMPLE POUR L'ENTRAINEMENT D'UNE TURBINE 22. DU LAITIER FONDU 5 PROVENANT D'UN HAUT FOURNEAU EST VERSE DANS UNE POCHE 45 ENTRE LES DEUX TAMBOURS ET EST SOLIDIFIE SOUS FORME D'UNE COUCHE RELATIVEMENT MINCE EN LIAITIER VITREUX 5 SUR LA SURFACE LATERALE DES TAMBOURS. UN RABOT 17 EN BAS ENLEVE LE LAITIER VITREUX. LES TAMBOURS 14 SONT REFROIDIS INTERIEUREMENT PAR UN CALOPORTEUR DONT LE POINT D'EBULLITION EST D'AU MOINS 200C A LA PRESSION ATMOSPHERIQUE ET QUI CIRCULE DANS UNE PARTIE DE L'ECHANGEUR 21. An apparatus for manufacturing a vitreous slag, which comprises: a pair of cooling drums, the peripheral surfaces of said pair of cooling drums being in contact with each other, and said pair of cooling drums rotating in directions opposite to each other at the same peripheral speed; a pair of weirs provided at the upper halves of the both ends of said pair of cooling drums so as to be in contact with said both ends of said pair of cooling drums, a slag sump being formed by means of said pair of weirs and the bodies of said pair of cooling drums, and molten slag being poured into said slag sump; a cooling medium for cooling said pair of cooling drums, said cooling medium comprising a high boiling point heat medium having a boiling point under 1 atmospheric pressure of at least 200 DEG C., said high boiling point heat medium being fed into each of said pair of cooling drums, exchanging heat with said molten slag in said slag sump, deposited onto the peripheral surfaces of said pair of cooling drums, and being discharged from each of said pair of cooling drums under a pressure of up to 5 kg/cm2 for heat recovery, whereby said molten slag is substantially completely converted into a vitreous slag through heat exchange with said high boiling point heat medium, and is peeled off from the peripheral surfaces of said pair of cooling drums by a scraper.
