Description

(54) ШИХТА ДЛЯ ИЗГОТОВЛЕНИЯ ОГНЕУПОРНЫХ ИЗДЕЛИЙ(54) FIELD FOR PRODUCTION OF REFRACTORY PRODUCTS

Изобретение относитс  к огнеупорным материалам и может использоватьс  дл  изготовлени  футеровок стекло варенных печей,дугогасительных камер и других изделий, работающих в услови х резких перепадов температур и в агрессивных средах. Известна шихта дл  изготовлени  огнеупоров, включающа  циркон и добавку пластинчатых монокристаллов окиси алюмини  в количестве 10- 20 вес.%. Прочность этого материала при сжатии составл ет 1700-1800кгс/с Наиболее близкой по технической сущности и достигаемому результату  вл етс  шихта дл  изготовлени  огне упорных изделий, включающа  50- 90 вес.% циркона,фракции 0,2-0,5 мм, 4-35 вес.% нестабилизированной двуокиси циркони  фракции менее 0,06 мм и 3-30 вес.% стабилизированной, двуокиси циркони  2. Недостатком огнеупоров, полученных из этих шихт,-  вл етс  сравнительно низка  механическа  прочность Цель изобретени  - повьвиенйе меха нической прочности. Это достигаетс  тем, что шихта Дл  изготовлени  огнеупорных изделий, включающа  циркон, двуокись циркони  стабилизированную и нестабилйзированную фракции менее 0,06 мм, содержит циркон фракции менее 0,2 мм при следующем соотнс дении компонентов, вес.%: Стабилизированна  Двуокись циркони  0,25-2,5 Нестабилизированна  двуокись циркони  0,25-3,5 Циркон фракции менее 0,2 Ъ9И Остальное Дл  получени  материала из шихты такого состава сырьевые материалы подвергали смешиванию в течение 0,5 ч. Затем из массы прессовали образцы (при удельном давлении 500 мг/см ) и обжигали при температуре 1620с. Конкретный состав предлагаемой шихты приведен в табл. 1. Свойства полученных образцов из предлагаемой и известной шихт приведены в табл. 2.The invention relates to refractory materials and can be used for the manufacture of linings for glass of boiled furnaces, arcing chambers and other products operating under conditions of sudden temperature changes and in corrosive environments. The known charge for the manufacture of refractories, including zircon and the addition of lamellar single crystals of alumina in an amount of 10-20 wt.%. The compressive strength of this material is 1700-1800 kgf / s. The closest to the technical essence and the achieved result is the charge for the manufacture of fire resistant products, including 50- 90 wt.% Zircon, fractions 0.2-0.5 mm, 4- 35% by weight of unstabilized zirconia fraction less than 0.06 mm and 3-30% by weight of stabilized zirconia dioxide 2. The disadvantage of refractories obtained from these materials is relatively low mechanical strength. The purpose of the invention is to improve mechanical strength. This is achieved by the fact that the charge for the manufacture of refractory products, including zircon, stabilized zirconia and unstable fractions less than 0.06 mm, contains less than 0.2 mm zircon fractions with the following ratio of components, wt.%: Stabilized zirconium dioxide 0.25 -2.5 Unstabilized Zirconia 0.25-3.5 Zircon fractions less than 0.25 °. Else To obtain material from a mixture of this composition, the raw materials were mixed for 0.5 h. Then, samples were pressed from the mass (at specific pressure 500 mg / m), and calcined at 1620s. The specific composition of the proposed mixture is given in table. 1. The properties of the samples obtained from the proposed and known charge are given in table. 2
