Description
Изобретение относитс к огнеупорной промышленности и может быть использовано в производстве высокоглиноземистых материалов дл футеровки различных тепловых агрегатов, в частности высокотемпературных нагревательных печей, воздухонагревателей доменных печей, сталеразливочных ковшей.The invention relates to the refractory industry and can be used in the production of high-alumina materials for lining various thermal units, in particular, high-temperature heating furnaces, air heaters for blast furnaces, steel teeming ladles.
Известна шихта дл изготовлени огнеупорных изделий, включающа 81- 84 вес. % смеси обожженного и необожженного глинозема и 16-19 :вес. % циркона 1.The known charge for the manufacture of refractory products, comprising 81- 84 weight. % mixture of calcined and unfired alumina and 16-19: weight. % zircon 1.
Наиболее близкой к предлагаемой по технической суш,ности и достигаемому результату вл етс шихта дл изготовлени огнеупорных изделий, включаюш,а , вес. %:Closest to the proposed technical dryness and the achieved result is the mixture for the manufacture of refractory products, including, as well, weight. %:
температуре начала деформации под нагрузкой .temperature of onset of deformation under load.
Цель изобретени - повышение плотности , прочности, термостойкости и температуры начала деформации под нагрузкой.The purpose of the invention is to increase the density, strength, heat resistance and temperature of the onset of deformation under load.
Поставленна цель достигаетс тем, что шихта дл изготовлени огнеупорных изделий, включающа кварцит, циркон и св зующее, дополнительно содержит глинозем при следующем соотношении компонентов , вес. % :This goal is achieved by the fact that the charge for the manufacture of refractory products, including quartzite, zircon and binder, additionally contains alumina in the following ratio of components, weight. %:
