СП 1 Изобретение относитс к шихте дл изготовлени безобжиговых монолитных футеровок и штучных изделий и может быть использовано, например, в металлургической промьшшенности. Известна шихта дл изготовлени безобжиговых изделий, включающа кварцит и огнеупорную глину. Издели из такой шихты имеют значительный рост при высоких температурах (2,5 3,5%), низкую термостойкость (12 теплосмены) и высокую кажущуюс пористость (до 30%), причем во врем службы при высокой температуре издели сильно разрыхл ютс . Описываема шихта, с целью повы шени плотности и термост-ойкости изделий, содержит указанные компоненты в следующих количествах, мае. %: йварцит 90-92, огнеупорна глина 8-10, и, кроме того, сверх . 100% раствор моноалюмофосфата плот ностью 1,45-1,70 г/см 5-15. При этом кварцит содержит сл:еду ;ие фракции, мае. %: 1-0,5 мм 40-78 0,5-0,088 мм . 2-15 0,088-0,0001 мм 15-40 Издели , изготовленные из описываемой шихты прессованием при давлении 800 кг/см, имеют после сушки при 120-150 0 механическую прочность 300-350 кг/см при пористости 14-16%. После обжига при 1350-1400°С механическа прочность и пористость изделий практически не мен ютс . Во врем обжига издели дают рост в пределах до 1%, а при повторном обжиге изменени их размеров и разрыхлени не наблюдаетс , структура остаетс плотной. Издели имеют следуюш 1е свойства: Термостойкость, водные теплосмены (1300°С - вода) Огнеупорность,С Температура деформации под нагрузкой 2 кг/см ,0 Кажуща с пористость , %14-16SP 1 The invention relates to a charge for the manufacture of unburned monolithic linings and piece goods and can be used, for example, in the metallurgical industry. A known charge for the manufacture of unburned products, including quartzite and refractory clay. Products from such a mixture have significant growth at high temperatures (2.5–3.5%), low heat resistance (12 heat exchanges) and high apparent porosity (up to 30%), and the product looses much during high temperature service. The described charge, in order to increase the density and thermal stability of products, contains the indicated components in the following amounts, May. %: Yvartzit 90-92, refractory clay 8-10, and, in addition, above. A 100% solution of monoaluminophosphate with a density of 1.45-1.70 g / cm 5-15. At the same time quartzite contains the following: food, its fraction, May. %: 1-0.5 mm 40-78 0.5-0.088 mm. 2-15 0,088-0,0001 mm 15-40 The products made of the described mixture by pressing at a pressure of 800 kg / cm have, after drying at 120-150 0, mechanical strength of 300-350 kg / cm with a porosity of 14-16%. After firing at 1350-1400 ° C, the mechanical strength and porosity of the products remain almost unchanged. During firing, the products give an increase in the range of up to 1%, and when fired again, no change in their dimensions and loosening is observed, the structure remains dense. The products have the following properties: Heat resistance, water heat exchange (1300 ° C - water) Fire resistance, C Temperature of deformation under load 2 kg / cm, 0 Appearing with porosity,% 14-16
