Description
Изобретение относитс к производству основных огнеупоров и может быть использовано при изготовлении футеровок, бетонных изделий, набивных масс, мертелей, обмазок дл печей и оборудовани металлургической , энергетической, химической промышленности, которые эксплуатируютс при температурах до 1600°С.The invention relates to the production of basic refractories and can be used in the manufacture of linings, concrete products, ramming masses, mortars, coatings for furnaces and equipment for the metallurgical, energy, chemical industry, which are operated at temperatures up to 1600 ° C.
Целью изобретени вл етс повышение прочности и уменьшение усадки.The aim of the invention is to increase the strength and reduce shrinkage.
Обработка огнеупорного заполнител перед смешиванием с цементом, кальций- содержащим магнийгидроалюминатным раствором создает на зернах поверхностный слой гидроксида магни в коллоидно- дисперсном состо нии при наличии центров кристаллизации.Processing the refractory filler before mixing with cement, calcium-containing magnesium hydroaluminate solution creates on the grains a surface layer of magnesium hydroxide in a colloid-dispersed state in the presence of crystallization centers.
Пример. Цемент предлагаемого химического состава получают из сырьевой смеси доломита, каустического магнезита, глинозема и хромита. Сырьевую смесь размалывают до тонины, характеризуемой прохождением 95% через сито № 006. Продукт помола брикетируют, обжигают при 1600°С и размалывают до тонины прохождени 95% через сито № 006.Example. The cement of the proposed chemical composition is obtained from the raw mix of dolomite, caustic magnesite, alumina and chromite. The raw meal is milled to a fineness characterized by 95% passage through sieve No. 006. The grinding product is briquetted, calcined at 1600 ° C and grinded to 95% passing through sieve No. 006.
Раствор дл обработки огнеупорного заполнител получают интенсивным перемешиванием каустического огнемагнезита, алюмината кальци и водыThe refractory aggregate treatment solution is obtained by vigorous agitation of caustic fire magnesite, calcium aluminate and water.
Огнеупорный заполнитель обрабатывают в растворе при 18°С.Refractory aggregate is treated in solution at 18 ° C.
После обработки огнеупорный заполнитель смешивают с цементом.After processing, the refractory aggregate is mixed with cement.
Составы и режимы изготовлени огнеупорных масс приведены в табл.1-5: в табл.1 - минералогический состав; в табл.2 - прочность огнеупоров с использованием корундового заполнител ; в табл.3 - с использованием периклазового заполнител ; в табл.4 - с использованием диоксидаThe compositions and modes of manufacture of refractory masses are given in Tables 1-5: Table 1 contains the mineralogical composition; in table 2 - the strength of refractories using corundum filler; in table 3 - using periclase filler; in table 4 - using dioxide
