Description
Известна шихта дл изготовлени цирконовых огнеупорных изделий, содержаща порошкообразный цирконовый брикет, обезжелезненный циркон и св зку, в качестве которой используют огнеупорную глину, каолин, AlaO,, MgO, фосфорную кислоту.The known charge for the manufacture of zircon refractory products, containing powdered zircon briquette, iron neutral zircon, and a bond, which is used as refractory clay, kaolin, AlaO ,, MgO, phosphoric acid.
Цель изобретени - улучшить формовочные свойства и качество изделий. Достигаетс это тем, что предложенна шихта содержит в качестве св зки кремнеоргаиическую смолу в количестве 8-12% по весу.The purpose of the invention is to improve the molding properties and quality of products. This is achieved by the fact that the proposed mixture contains, as a binder, an organosilicon resin in an amount of 8-12% by weight.
Изготовл ют данную шихту следуюш;им образом .This mixture is manufactured in the following way.
Цирконовый брикет прессуют из циркона на сульфитно-спиртовой барде в качестве св зки. Содержание барды должно составл ть не менее 2э/о на вес сухого веш,ества сверх 100%. В случае необходимости получени плотного цирконового брикета можно в качестве св зки применить до 5% смолы Ф-9. Обжиг брикета производ т при температуре 1560- 1600°С. Затем осуществл ют размол на фракции 2-0,5 мм и меньше 0,5 мм.A zircon briquette is pressed from zircon on sulfite-alcohol bard as a binder. The content of bards must be at least 2e / o by weight of dry weight over 100%. If it is necessary to obtain a dense zircon briquette, up to 5% of resin F-9 can be used as a binder. The briquette is fired at a temperature of 1560 - 1600 ° C. Then grinding into fractions of 2-0.5 mm and less than 0.5 mm is carried out.
45% порошкообразного цирконового брикета смешивают с 55Vo обезжелезненного циркона и 8-12% кремнеорганической смолы Ф-9. Кремнеорганическа смола Ф-9 резко улучшает прессуемость шихты, позвол ет полностью избежать брак по прессовочным трещинам и изготовл ть крупногабаритные издели с объемным весом сырца 3,38-3,40 г/смз. Разлага сь в обжиге, она образует аморфную окись кремни , котора вл етс прекрасной спекающей добавкой, позвол ющей получить издели с пористостью 5-7а/о.45% of powdered zircon briquette is mixed with 55Vo of iron-free zircon and 8-12% of silicon-like resin F-9. Silicone resin F-9 dramatically improves the compressibility of the charge, completely avoids the marriage of pressing cracks and manufactures large-sized products with a raw weight of 3.38-3.40 g / cm 3. When decomposed in roasting, it forms amorphous silicon oxide, which is an excellent sintering additive, which makes it possible to obtain products with a porosity of 5-7a / o.
