Title (EN) SPINEL REFRACTORY GRANULATES WHICH ARE SUITABLE FOR ELASTICIZING HEAVY-CLAY REFRACTORY PRODUCTS, METHOD FOR THEIR PRODUCTION AND USE THEREOF
(FR) GRANULATS DE SPINELLE IGNIFUGES CONVENANT POUR RENDRE ÉLASTIQUES DES PRODUITS IGNIFUGES EN CÉRAMIQUE GROSSIÈRE, PROCÉDÉ POUR LES RÉALISER ET LEUR UTILISATION
(DE) ZUR ELASTIFIZIERUNG VON GROBKERAMISCHEN FEUERFESTERZEUGNISSEN GEEIGNETE FEUERFESTE SPINELLGRANULATE, VERFAHREN ZU IHRER HERSTELLUNG UND IHRE VERWENDUNG
Abstract:
(EN) The invention relates to a granular refractory mineral elasticizing granulate for refractory products, in particular for basic refractory products, wherein the minerals consist of mono-phase fused spinel mixed crystals or multi-phase fusion products of the ternary system MgO-Fe2O3-Al2O3 of the composition range MgO: 12 to 19.5, in particular 15 to 17 wt.-%, remainder: Fe2O3 and Al2O3 in a quantity ratio range of Fe2O3 to Al2O3 between 80 to 20 and 40 to 60 wt.-%, the respective mixed crystals having an Fe2O3 and Al2O3 content in a solid solution, starting from an MgO content between 12 and 19.5 wt.-%, from the limited ranges indicated for each case, to obtain 100% in the total composition. The invention also relates to a method for producing said elasticizing granulate and to the use of the same.
(FR) La présente invention concerne un granulat d’élastification minéral ignifuge granulaire destiné à des produits ignifuges, notamment à des produits ignifuges basiques, se composant d’un point de vue minéral respectivement d’un cristal mixte de spinelle de frittage monophasique ou d’un produit de fusion polyphasique du système à trois composantes MgO-Fe2O3-Al2O3 avec une composition de l’ordre de MgO: 12 à 19,5, notamment 15 à 17 % en poids, reste : Fe2O3 et Al2O3 avec des rapports quantitatifs de Fe2O3 à Al2O3 de l’ordre de 80 à 20 et 40 à 60 % en poids, les cristaux mixtes respectifs ayant, à partir d’une teneur en MgO de 12 à 19,5 % en poids, une teneur respective en Fe2O3 et Al2O3 en solution solide dans les plages de valeurs délimitées comme respectivement approprié, de sorte que l’on obtient un total de 100 % pour l’ensemble de la composition. L'invention concerne en outre un procédé pour produire ce granulat d’élastification et son utilisation.
(DE) Die Erfindung betrifft ein körniges feuerfestes mineralisches Elastifizierergranulat für Feuerfesterzeugnisse, insbesondere für basische Feuerfesterzeugnisse, mineralisch bestehend jeweils aus einem monophasigen Schmelzspinellmischkristall oder mehrphasigen Schmelzprodukt des Dreistoffsystems MgO-Fe2O3-AI2O3 aus dem Zusammensetzungsbereich MgO: 12 bis 19,5, insbesondere 15 bis 17 Gew.-% Rest: Fe2O3 und Al2O3 im Mengenverhältnisbereich Fe2O3 zu Al2O3 zwischen 80 zu 20 und 40 zu 60 Gew.-% wobei ausgehend von einem MgO-Gehalt zwischen 12 bis 19,5 Gew.-% die jeweiligen Mischkristalle jeweils einen Fe2O3- und Al2O3-Gehalt in fester Lösung aus den dafür jeweils angegebenen begrenzten Bereichen derart enthalten, dass sich eine Gesamtzusammensetzung zu 100 % ergibt. Die Erfindung betrifft außerdem ein Verfahren zur Herstellung des Elastifizierergranulats sowie dessen Verwendung.
