Description
Изобретение может быть использовано в доменных печах металлургических заводов при производстве чугуна. Известна глазурь дл защиты футеровки доменной печи, включающа SiO2, АЬОз, СаО. Цель изобретени - повыщение огнеупорности и шлакоустойчивости рабочей поверхности футеровки воздушных фурм доменной печи . Это достигаетс тем, что глазурь содержит указанные компоненты в следующих количествах (вес. %): SiOa и, кроме того, 25-27 0,9-1,2 Описываема глазурь Имеет следующие свойства: Темлература разлива глазури, °С Температура разм гчени глазури при повторном нагреве, °С Растрескивание и отслоение глазури при 20-кратном нагреве до i 1500°C Не обнаружено Химического взаимодействи сло глазури дри 20-кратном погружении глазурованной плитки в струю движущегос доменного шлака с температурой 1480-1520°С не обнаружено . Применение описываемого состава глазури .дл покрыти рабочей поверхности футеровки фурм обеспечивает срок службы фурмы - Л О-12 Мес цев. Предмет изобретени Глазурь дл защиты футеровки воздушных фурм доменной печи, включающа SiOa, АЬОз, СаО, отличающа с тем, что, с целью повышени огнеупорности и щлакоустойчивости рабочей поверхности футеровки воздушных фурм доменной печи, она содержит указанные компоненты в следующих количествах (вес. %): SiOa20-23 АЬОз38-40 СаО11 - 13 и, кроме того, 25-27 TiOa 0,9-1,2The invention can be used in blast furnaces of metallurgical plants in the production of iron. Known glaze to protect the lining of a blast furnace, including SiO2, ABOz, CaO. The purpose of the invention is to increase the refractoriness and slag resistance of the working surface of the lining of air tuyeres of the blast furnace. This is achieved by the fact that the glaze contains the indicated components in the following amounts (wt.%): SiOa and, in addition, 25-27 0.9-1.2 The glaze described has the following properties: Temlaratura of the glaze spill, ° C The softening temperature of the glaze when reheating, ° C. Cracking and peeling of the glaze at 20-fold heating to i 1500 ° C. Not detected. Chemical interaction of the glaze layer and 20-fold immersion of the glazed tile into the jet of the blast furnace slag with a temperature of 1480-1520 ° C was not detected. The use of the described composition of the glaze. For coating the working surface of the lining of the tuyeres ensures the service life of the tuyere - L O-12 Month. The subject of the invention Glaze to protect the lining of air blast furnace tuyeres, including SiOa, ABOz, CaO, characterized in that, in order to increase the refractoriness and resistance of the working surface of the blast furnace tuyeres lining, it contains these components in the following amounts (wt.%) : SiOa20-23 AL3838-40 CaO11 - 13 and, moreover, 25-27 TiOa 0.9-1.2
