Изобретение -относитс к производству в жущих материалов и может исполь-. зоватьс в промьпиленности строительных материалов.The invention relates to the production of living materials and can be used. appear in industrial materials.
Известна сырьева смесь дл производства цементного клинкера, включающа , %: известковый компонент 74-79 j глинистый компонент 19-24 ; железосодержащий компонент 0,5-2 и комплексную добавку, состо щую из Ti Oj -0,61 ,0,- ZnO - 0,6-1,0, BjOi - 0,3 0 ,5% 11 ..The known raw mix for the production of cement clinker, including,%: limestone component 74-79 j clay component 19-24; an iron-containing component of 0.5-2 and a complex additive consisting of Ti Oj -0.61, 0, - ZnO - 0.6-1.0, BjOi - 0.3 0, 5% 11 ..
Наиболее близкой по технической сущности и достигаемому эффекту к насто щему изобретению вл етс сырьева смесь дл получени цементного клинке- ра, включающа , %: известн ковый компонент 79-93, iaлюмocиликaтный KQM .понент 3,5-20,5, корректирукший компонент , состо щий из продукта очистки серной кислоты, содержащей сернокислое железо 3,5-6,5 21 .The closest to the technical essence and the achieved effect to the present invention is the raw mix for the production of cement clinker, including,%: limestone component 79-93, i-luminescent KQM. Component 3.5-20.5, corrected component, condition from the sulfuric acid cleaning product containing ferrous sulphate 3.5-6.5 21.
Недостатками известной сырьевой смеси вл ютс низка скорость процессаThe disadvantages of the known raw material mixture are low speed of the process.
клинкерообразовани и недостаточна прочность цемента.clinker formation and cement strength is insufficient.
Цель изобретени - ускорение проlecca клинкерообразовани н повьпиение прочности цемента.The purpose of the invention is the acceleration of clinker formation and cement strength.
Поставленна цель достигаетс тем, что сырьева смесь дл получени портландцементного клинкера, включающа известн ковый, алюмосиликатный, желеto зосодержащий компоненты и добавку, в качестве добавки содержит отход сернокислотного производства двуокиси титана при следующем соотношений компонентов , вес.%: /This goal is achieved by the fact that the raw mix for obtaining portland cement clinker, including limestone, aluminosilicate, gelled components and an additive, contains an additive of sulfuric acid titanium dioxide production as an additive in the following ratios of components, wt.%: /

При введении в состав цементных сырьевых смесей добавки железогипса, вследствие увеличени в ее составе окис -Т обладающих пониженной поверхностной активностью, и уменьш к количе Ьва наиболее noaepxHocTHOt 0KTifBHoro окисла SOa, в печи образо- рываютс обладающие большой гидраиионной активностью клинкерные гранулы размером 5-2О мм, что и приводит к повышению марочноети цемента.When iron-gypsum additives are added to cement raw mixes, due to an increase in its composition —T having a lower surface activity, and reducing the amount of SOh to the most noaepxHocTHOt 0KTifBHoro oxide of SOa, 5-2O2 , which leads to an increase in the cement grade.
Готовые с.ерьвые смеси обжигают при 1400, 1350, 1300°С,.полученные спеки размалывают.Ready s.erve mixes are burned at 1400, 1350, 1300 ° С, the grinders produced are ground.
Состав сырьевь1Х смесей и прочностные характеристики цементов на основе nonvneHHbix клинкеров приведены в т:аблице .The composition of raw material mixtures and the strength characteristics of cements based on nonvneHHbix clinkers are given in t: table.
Таким образом, введение с состав цементных сырьевых смесей добавки железогипса увеличивает скорость реакций клинкерообразовани , улучшает работу вращающихс печей, повьпиает гид- ратационную активность клинкера.Thus, the introduction of iron-gypsum additive to the composition of cement raw mixes increases the rate of clinker formation reactions, improves the performance of rotary kilns, increases the hydration activity of the clinker.
