Description
Плавка в электрических дуговых печах белого электрокорунда из глинозема сопровождаете значительными иотер ми гли1юзема, уносимого печными га:.ами в атмосферу.Melting in electric arc furnaces of white electrocorundum from alumina is accompanied by significant sources of glyulese carried by furnace hectares: to the atmosphere.
Известны снособы брикетировани глинозема, в цел х уменьшени его уноса, с нрименением органических св зок, которые при нагревании иа колошнике печи разлагаютс , а образующийс нри этом порошкообразный глинозем уноситс печными газами , что не позвол ет эти снособы внед)ить в производство.Dust briquetting alumina is known, in order to reduce its entrainment, with the use of organic bindings, which decompose when heated in the furnace head, and the resulting alumina powder is carried away by furnace gases, which prevents these demolitions from being put into production.
Г1р ; кч1ение .еоргаиичесикх в жущих веществ сильио ограничиваетс вредным вли нием небольших количеств Na.,O, К.,0, СаО, .VI рО.G1p; The exclusion of organic substances in syringes is limited by the harmful effects of small amounts of Na., O, K., 0, CaO, .VI pO.
В цел х св зывани имеющихс в глиноземе этих вредных примесей и повьнпеии таким образо.м качества белого электрокорунда, к глинозему добавл етс 2-4% кремнезема в виде чистого кварца.In order to bind these harmful impurities present in alumina and in such a manner as white electrocorundum, 2-4% silica in the form of pure silica is added to alumina.
Описываемый способ предусматривает применение в качестве св зки дл брикетироваии глииозема каолиновой глины, котора повышаетThe described method involves the use of kaolin clay as a binder for the briquetting of gliozem, which increases
содержание кре.мнезема Р. нпгхте до 2%, что исключает дополнительную добавку чистого кварца и обеспечивает прочность брпкетов до расплавлени глинозема в нечи.the Creme's silica content is up to 2%, which excludes the additional addition of pure quartz and ensures the strength of the briquettes before the alumina melts in some way.
По описывае: юму способ} шннозем смешивают с каолиновой глиной в количестве о-10% от его веса и с водой в количестве 16-35% от веса сухой массы.According to the description: the Yuma method} is mixed with kaolin clay in the amount of about 10% of its weight and with water in the amount of 16-35% of the weight of the dry mass.
