Abstract

Η εφεύρεση σχετίζεται με άκαυστο πυρότουβλο που περιέχει γραφίτη που προορίζεται για καμίνια της βιομηχανίας τσιμέντου και με την χρήση του εν λόγω πυρότουβλου στα προηγούμενα αναφερόμενα καμίνια τσιμέντου ώστε να αντιμετωπίσουν την συναφή θερμική και φυσικό-χημική παραμόρφωση. Η σύνθεση του τούβλου της εφεύρεσης περιέχει μεταξύ 75 και 62 % κατά βάρος μαγνησίτη (MgCO3), μεταξύ 12 και 20 % κατά βάρος αλουμίνα (Αl2Ο3) και μεταξύ 4 και 11 % κατά βάρος γραφίτη. Η εν λόγω σύνθεση περιέχει επίσης μεταξύ 9 και 7 % κατά βάρος πρόσθετα που χρησιμοποιούνται για να βελτιώσουν την αντοχή σε θερμικό σοκ, την θερμική αντοχή και την αντοχή σε οξείδωση (σε μία σύνθεση που περιέχει σκόνη αργιλίου, μέταλλο πυριτίου, καρβίδιο πυριτίου και άργιλο) και μεταξύ 3 και 4 % κατά βάρος ρητίνες. Το εν λόγω πυρίμαχο υλικό χρησιμοποιείται για την επένδυση των καμινιών τσιμέντου στην υψηλή και χαμηλή μεταβατική ζώνη (4) καθώς και στην ζώνη πυροσυσσωμάτωσης (5).
