Description
Изобретение относитс к составам сырьевых смесей при производстве глиноземистого цемента.FIELD OF THE INVENTION The invention relates to compositions of raw materials for the production of high alumina cement.
Цель изобретени - повьш1ение прочности и стабилизаци ее роста.The purpose of the invention is to increase strength and stabilize its growth.
Пример. Сырьевые смеси готов т путем перемешивани двух шламов. Шлам алюмосульфокальциевый (АСШ) образуетс в процессе многоступенчатой очистки сточных вод обработки алюминиевых сплавов и имеет химсостав, мас.%: , 323-38Example. Raw mixes are prepared by mixing the two slurries. Aluminosulfocalcium (ACS) sludge is formed in the process of multistage sewage treatment of aluminum alloys and has a chemical composition, wt.%:, 323-38

Минеральна часть КАШ в основном представлена кальцитом (50-60 мас.%) и бёмитом.The mineral part of the KSB is mainly represented by calcite (50-60 wt.%) And boehmite.
-В процессе обжига смесь шламов про вл ет большую реакционную способность , вследствие высокой степени дисперсности ( 3 10000 ) и гомогенности (на молекул рном уровне) шихты. Эти характеристики обусловлены происхождением шламов путем химического вьщелени из растворов. Обжиг .смесей осуществл ют при 1400-1440 С.In the firing process, the mixture of sludge exhibits a high reactivity due to the high degree of dispersion (3 10,000) and homogeneity (at the molecular level) of the charge. These characteristics are due to the origin of the sludge by chemical separation from solutions. Roasting of the mixtures is carried out at 1400-1440 C.
