Abstract
1. Способ корректировки состава алитового портландцементного клинкера на основе высокосульфатной сырьевой смеси, состоящей из карбонатной породы, глины, гипса и корректирующих добавок, включающий сушку сырьевых компонентов, экспресс анализ их химического состава, расчет состава сырьевой смеси, ее шихтовку, совместный помол компонентов сырьевой смеси, гомогенизацию, кальцинацию, обжиг сырьевой смеси до клинкера и его помол с технологическими добавками, отличающийся тем, что при содержании в сырьевой смеси SOболее 2,0%, расчет состава сырьевой смеси ведут в два этапа, на первом этапе расчет ведут на формирование в клинкере портландцемента моноалюмината кальция СА при коэффициенте насыщения КН=1 и степенях насыщения СН=0 или СН=1, а на втором этапе расчет ведут на основе сырьевой смеси, компонентами которой являются клинкер, полученный на первом этапе расчета без учета SO, и корректирующие добавки, при этом расчет ведут на получение алитового портландцементного клинкера, содержащего CS, CS и CAF при коэффициентах насыщения от КН=0,92 до 0,98, глиноземистых модулях от p=1,7 до 4,0 и кремнеземных модулях от n=2,0 до 3,0, а при шихтовке сырьевой смеси, ее расчетный состав корректируют путем уменьшения количества рассчитанной глины от 4,0 до 20% и введения корректирующих добавок от 4,0 до 23%.2. Способ по п.1, отличающийся тем, что в качестве корректирующей добавки вводят кварцевый песок.3. Способ по п.1, отличающийся тем, что в качестве корректирующей добавки вводят гидроксид алюминия.4. Способ по п.1, отличающийся тем, что в качестве корректирующей добавки вводят карбонатную породу.1. A method for adjusting the composition of alite Portland cement clinker based on a high-sulfate raw mix consisting of carbonate rock, clay, gypsum and corrective additives, including drying the raw components, express analysis of their chemical composition, calculation of the composition of the raw mix, its blending, joint grinding of the raw mix components , homogenization, calcination, firing the raw material mixture to clinker and grinding it with technological additives, characterized in that when the content of the raw material mixture is more than 2.0%, the calculation of the composition of the raw materials The mixture is carried out in two stages, at the first stage, the calculation is carried out to form calcium monoaluminate CA in clinker of Portland cement at saturation coefficient KH = 1 and degrees of saturation CH = 0 or CH = 1, and at the second stage, the calculation is based on the raw material mixture, the components of which are the clinker obtained at the first stage of the calculation without taking into account SO, and corrective additives, while the calculation leads to an alite Portland cement clinker containing CS, CS and CAF with saturation coefficients from KN = 0.92 to 0.98, alumina modules from p = 1.7 to 4.0 and silica 's modules from n = 2,0 to 3,0, and at burdening the raw mix, its calculated composition is adjusted by reducing the amount calculated clay from 4.0 to 20%, and introducing corrective additives from 4.0 to 23% .2. The method according to claim 1, characterized in that quartz sand is introduced as a corrective additive. The method according to claim 1, characterized in that aluminum hydroxide is introduced as a corrective additive. The method according to claim 1, characterized in that carbonate rock is introduced as a corrective additive.
