Description
Изобретение относитс к технолог производства белого портландцемента в частности к составу сырьевых смесей дл получени белого портландцементного клинкера. Известна сырьева смесь дл производства клинкера белого портландцемента , включающа карбонатный и алюмосиликатный компоненты 1. . Наиболее близкой к предлагаемой по технической сущности и достигаемому результату известна сырьева смесь дл получени белого портланд цементного клинкера (2, включающа известн ковый, алюмосиликатный компоненты и электротермофосфорный шлак при следующем соотношении компонентов , вес.%: Известн ковый компонент68-72 Алюмосиликатный компонент7.-9 Электротермофосфорный шлак21-23 Недостатком известной сырьевой смеси вл етс невысока степень белизны клинкера. Цель изобретени - повышение степени белизны клинкера. Поставленна цель достигаетс тем, что сырьева смесь дл получени белбго портландцементного клинкера, включающа известн ковый,алюмосили- , катный компоненты и электротермофосфорный шлак, содержит указанные ком- I поненты при следующем соотношении, вес.%: Известн ковый компонент58-68 Алюмосиликатный компонент1-6,9 Электротермофосфорный шлак 25,1-41 Сущность изобретени заключаетс в следующем. CjA, независимо от способа отбеливани (газовое или водное), обожженный с окислами железа в количестве до 2%, практически не окрашиваетс , а с добавкой соединений марганца даже в количестве 0,1% приобретает интенсивную окраску, котора с увеличением последнего до 2% измен етс от розового до коричневого цвета. По данным статистического химического анализа в состав электротермофосфорных шлаков входит от 0,1 до 0,3 МпО; Дл известных составов сырьевых смесей белого портландцемента это количество MnQ. вл етс .совершенно недопустиNBiM , так как происходит резкое сниж ние , белизны клинкера, из-за высокого содержани алюминатной фазы, котора интенсивно;окрашиваетс окисью MupraHifa. Поэтому уменьшение в срставе сырьевой смеси доли каолина, в котором содержитс до 26-30% , и| увеличение содержани фосфорного шлака, в котором, количество с на-j хрдитс в пределах 1-3% при высокомThis invention relates to a process for the production of white Portland cement, in particular, to the composition of raw mixes for the production of white Portland cement clinker. The known raw mix for the production of white Portland cement clinker, including carbonate and aluminosilicate components 1.. The raw mix for obtaining white portland cement clinker (2, including limestone, aluminosilicate components and electrothermophosphoric slag in the following ratio, wt.%: Limestone component 68-72 Aluminosilicate component7. -9 Electrothermophosphoric slag21-23 A disadvantage of the known raw mix is the low whiteness of clinker. The purpose of the invention is to increase the whiteness of clinker. It is believed that the raw mix for producing Belbgo Portland cement clinker, including limestone, aluminosilicate, catnah components and electrothermophosphoric slag, contains the indicated components in the following ratio, wt.%: Calcium 5858 Aluminosilicate component 1-6.9 Electrothermophosphorus slag 25.1-41 The essence of the invention is as follows: CjA, regardless of the bleaching method (gas or water), calcined with iron oxides in an amount up to 2%, practically does not stain, and with the addition of manganese compounds and e in an amount of 0.1% becomes intense color, which latter with the increase to 2% varies from pink to brown. According to the statistical chemical analysis, the composition of electrothermophosphorus slags includes from 0.1 to 0.3 MpO; For known compositions of raw mixtures of white Portland cement, this is the amount of MnQ. NBiM is completely unacceptable, as there is a sharp decrease in the whiteness of the clinker, due to the high content of the aluminate phase, which is intense; it is stained with MupraHifa oxide. Therefore, a decrease in the amount of kaolin in the raw meal mixture, which contains up to 26-30%, and | an increase in the content of phosphorus slag, in which, the amount of from-j hrits within 1-3% at high
КН (U,90-1,00), позвол ет повысить белизну клинкера.KN (U, 90-1.00), allows to increase the whiteness of the clinker.
Предлагаема сырьева смесь позвол ет получать высокоёшит вые клинкеры с КН 0,90-0,99, содержание алюминатной фазы в которых понижено о 3-9%.The proposed raw mix makes it possible to produce high-yielding clinkers with a CN of 0.90-0.99, the content of the aluminate phase in which is reduced by about 3-9%.
