Description
. .1 . . .one .
Изобретение относитс к составам огнеупорных изделий, предназначенных дл работы в стекловаренных печах.The invention relates to compositions of refractory products intended for use in glass melting furnaces.
Известна шихта дл изготовлени огнеупорных изделий, включающа окись хрома, двуокись титана, окись магни .A known charge for the manufacture of refractory products, including chromium oxide, titanium dioxide, and magnesium oxide.
Цель изобретени - повышение прочности и стеклоустойчивости, снижение смачиваемости. Достигаетс это тем, что шихта дополнительно содержит глину при следующем соотношении компонентов, вес.:The purpose of the invention is to increase the strength and glass resistance, reducing wettability. This is achieved by the fact that the mixture additionally contains clay in the following ratio of components, weight:
89-97 89-97
Окись хрома 1-5 Двуокись хрома Chromium Oxide 1-5 Chromium Dioxide
°& Окись магни Глина° & Clay Oxide
ПРИМЕР. Окись хрома измельчают до размера зерен менее 8 мкм. Шихту составл ют в следующем соотношении (вес.):EXAMPLE. Chromium oxide is crushed to a grain size of less than 8 microns. The mixture is in the following ratio (wt.):
Окись хрома . . 92 Двуокись титана 3,5Chromium oxide. . 92 Titanium Dioxide 3.5

Шихту смешивают, прессуют при давлении 500 кг/см и обжигают при с выдержкой 6 час. Пористость изделий 8, плотность 4,73 г/см-, предел прочности, при сжатии 2400-3500 кг/см2.The mixture is mixed, pressed at a pressure of 500 kg / cm and calcined with a holding time of 6 hours. The porosity of the products is 8, the density is 4.73 g / cm-, the ultimate strength, in compression is 2400-3500 kg / cm2.
