Description
Известен электроилавленый огнеупорный материал дл стекловаренных печей, включающий ZrOs, и СаО.Known electrofusion refractory material for glass furnaces, including ZrOs, and CaO.
Однако в стекловаренных нечах из такого материала можно производить варку стекла при температуре, не превышающей 1600°С и получать стекла с температурой разм гчени не выше 900°С.However, in glass melts from such a material, it is possible to make glass melting at a temperature not exceeding 1600 ° C and to obtain glasses with a softening temperature not higher than 900 ° C.
Дл радиотермической промышленности требуютс стекла с те у1пературой разм гчени , превышающей 1000°С, а также огнеупорный материал дл бассейнов стекловаренных печей , позвол ющий производить варку стекол при температуре 1700-1800°С.Glasses with a softening temperature exceeding 1000 ° C, as well as refractory material for glass-melting furnace pools, which allow the glass to be cooked at a temperature of 1700-1800 ° C, are required for the radio thermal industry.
Предлагаетс электроплавленый огнеупорный материал с повышенной стеклоустойчивостью . Он содержит те же компоненты в сле/жующем процентном соотношении: ZrO.SS-65; AlaOaSO-40; СаО 4,5-5,5. Предлагаемый электроплавленый огнеупорный материал характеризуетс небольшими объемными изменени ми нри полиморфных превращени х при t IOOO-1200 0 и обладает хорошими литейными свойствами.An electrofusion refractory material with improved glass resistance is available. It contains the same components in the following percentage: ZrO.SS-65; AlaOaSO-40; CaO 4.5-5.5. The proposed electrofused refractory material is characterized by small volumetric changes in polymorphic transformations at t IOOO-1200 0 and has good casting properties.
Предмет изобретени Subject invention
Электроплавленый огнеупорный материал дл стекловаренных печей, включающий ZrOg, AlaOs, СаО, отличающийс тем, что, с целью увеличени стеклоустойчивости при t 1700- 1800°С, указанные компоненты составл ют по весу: ZrOa 55-65о/о; AUOa 30-40о/о; СаО 4,5- 5,5%.Electrofusion refractory material for glass melting furnaces, including ZrOg, AlaOs, CaO, characterized in that, in order to increase glass stability at t 1700-1800 ° C, these components are by weight: ZrOa 55-65o / o; AUOa 30-40 o; CaO 4.5 - 5.5%.
