Abstract
Przedmiotem zgłoszenia jest bezcementowy ogniotrwały beton korundowo-spinelowy, który składa się ze spiekanego lub topionego kruszywa korundowego o uziarnieniu 0,2 - 6,0 mm w ilości 60 - 65% masowych, elektrokorundu białego o uziarnieniu poniżej 0,1 mm w ilości 10 - 12% masowych, mieszaniny aktywowanych mechanicznie do uziarnienia poniżej 63 µm: tlenku glinu oraz spiekanego lub topionego tlenku magnezu w łącznej ilości 25 - 28% masowych, wodnej 40 - 50% zawiesiny nano-cząstek tlenku glinu w ilości 1,0 - 4,0% masowych w stosunku do masy suchych składników, organicznego dodatku upłynniającego na bazie glikolu polietylenowego w ilości do 0,2% masowych w stosunku do masy suchych składników oraz wody w ilości 2,0 - 5,0% masowych w stosunku do masy suchych składników. Przedmiotem zgłoszenia jest także sposób otrzymywania prefabrykatu z bezcementowego ogniotrwałego betonu korundowo-spinelowego, który polega na tym, że do kruszywa korundowego dodaje się wodną 40 - 50% zawiesinę nano-cząstek tlenku glinu oraz 40 - 60% przewidzianej ilości wody i całość miesza przez okres 2 - 3 minut. Następnie dodaje się mieszaninę tlenku glinu oraz drobnoziarnistego elektrokorundu białego i miesza przez okres 1 - 2 minut. Następnie dodaje się pozostałą część wody i organiczny dodatek upłynniający na bazie glikolu polietylenowego i miesza się przez okres 1 - 2 minut. Z kolei dodaje się tlenek magnezu mieszając wszystkie składniki aż do uzyskania żądanej półpłynnej konsystencji masy, z której otrzymuje się prefabrykat znanym sposobem.The subject of the application is cementless refractory corundum-spinel concrete, which consists of sintered or fused corundum aggregate with a grain size of 0.2 - 6.0 mm in the amount of 60 - 65% by weight, white electrocorundum with a grain size less than 0.1 mm in the amount of 10 - 12% by weight, a mixture of mechanically activated to a grain size below 63 μm: aluminum oxide and sintered or fused magnesium oxide in a total amount of 25 - 28% by weight, aqueous 40 - 50% suspension of nano-alumina particles in the amount of 1.0 - 4.0 % by mass with respect to the mass of dry ingredients, an organic flow additive based on polyethylene glycol in an amount of up to 0.2% by mass in relation to the mass of dry ingredients and water in an amount of 2.0 - 5.0% by mass in relation to the mass of dry ingredients. The subject of the application is also a method of obtaining a prefabricated element of cementless refractory alumina-spinel concrete, which consists in adding an aqueous 40 - 50% suspension of alumina nano-particles and 40 - 60% of the intended amount of water to the alumina aggregate and mixing it for a period 2 - 3 minutes. A mixture of alumina and fine white electrocorundum is then added and mixed for 1-2 minutes. The remainder of the water and the organic polyethylene glycol flow additive are then added and mixed for a period of 1-2 minutes. The magnesium oxide is then added, mixing all the ingredients until the desired semi-fluid consistency of the mass is obtained, from which the preform is obtained in a known manner.
