Description

Изобретение относитс  к ироизводству алюмини  электролизом. Известна шихта дл  подовой массы алюминиевых электролизеров, имеюща  следующий состав, %: Искусственный графит45-65 Термоантрацит15- 35 Каменноугольный среднетемпературный пек18-24 Предлагаема  щихта отличаетс  от известной тем, что в качестве св зующего применена каменноугольна  смола и органическа  пластифицирующа  добавка (например, олеинова  кислота), а щихта имеет следующий состав, %: Литейный кокс30-35 Искусственный графит 5--10 Смола каменноугольна 4-7 от веса Органическа  пластифицирующа  добавка 0,1-0,2 Термоантрацит Остальное. По сравнению с пеком каменноугольна  смола  вл етс  более поверхностно-активным веществом, хорошо смачивает твердые компоненты шихты, обладает высокой способностью внедр тьс  в толп1у коксовых зерен. Все сухой щихты эти свойства каменноугольной смолы и введение пластифицирующей добавки в количестве 0,1-0,2% от веса сухой шихты, позвол ют снизить количество св зующего в шихте и улучшить качество подовых швов, а также уменьшить образование усадочных трещин и щелей в процессе обжига подины. Предмет изобретени  1.Шихта дл  подовой массы алюмитщевых электролизеров, содержаща  термоантрацит, литейный кокс, искусственный графит и св зующее , отличающа с  тем, что, с целью увеличени  ПЛОТ1ШСТИ подовых щвов, в качество св зующего применена каменноугольна  смола и ограническа  пластифицирующа  добавка , а шихта имеет следующий состав, %: Литейный кокс30-35 Искусственный графит 5-10 Смола каменноуголь}1а 4-7 от веса Органическа  плассухой тифицирующа  шихты добавка0,1-0,2 ТермоантрацитОстальное. 2.Шихта по п. 1, отличающа с  тем, что в качеетве органической пластифицирующей добавки примснепа олеинова  кислота.The invention relates to the production of aluminum by electrolysis. The known charge for the bottom mass of aluminum electrolysis cells, having the following composition,%: Artificial graphite 45-65 Thermoanthracite 15- 35 Coal medium temperature peck18-24 The proposed blend differs from the known one in that coal tar and organic plasticizer are used as a binder (for example, as an binder and as an adhesive plasticizing agent (for example, an resin used as a binder and an organic plasticizing agent (for example, an resin used as a binder and an organic plasticizing agent (for example, used as a binder) ), and the substance has the following composition,%: Foundry coke 30-35 Artificial graphite 5--10 Coal tar 4-7 by weight Organic plasticizing agent 0.1-0.2 Thermoanthracite Else. Compared with pitch, coal tar is a more surfactant, well wets the solid components of the charge, has a high ability to penetrate into the masses of coke grains. All of these dry properties of coal tar and the introduction of a plasticizer in an amount of 0.1-0.2% of the dry weight of the mixture, reduce the amount of binder in the mixture and improve the quality of the bottom seams, as well as reduce the formation of shrinkage cracks and crevices in the process. roasting the bottom. The subject matter of the invention 1. A mixture for the bottom mass of alumina electrolyzers, containing thermoanthracite, foundry coke, artificial graphite and a binder, characterized in that, in order to increase the DUTY of the bottom chvov, coal tar and a plasticizing agent are used as the binder, It has the following composition,%: Foundry coke30-35 Artificial graphite 5-10 Coal tar} 1a 4-7 by weight Organic Dust typical charge blend additive 0,1-0,2 Thermo anthracite Else. 2. A mixture according to claim 1, characterized in that oleic acid is used as an organic plasticizing agent.
