Description
Известен способ иолучени аЛюмомагнезИальной шпинели из тонкомолотон смеси технического глинозема и обожженного магнезита. Синтез осуществл ют снлавлением смеси.There is a known method of obtaining aluminum lumomagnesial spinel from a fine grind of a mixture of technical alumina and calcined magnesite. The synthesis is carried out by firing the mixture.
Целью даниого изобретени вл етс улучшение физико-химических и механических свойств.The aim of the invention is to improve the physicochemical and mechanical properties.
Достигаетс это тем, что в расплав каолина с добавками антрацита и железной стружки ввод т .магнезит в количестве, обеспечиваюш ,ем содержание 5-35 вес. з/ MgO в шиинели .This is achieved by introducing into the molten kaolin with the addition of anthracite and iron shavings magnetite in an amount that ensures the content of 5-35 wt. C / MgO in Fiinel.
Сугцность предлагаемого способа заключаетс в следующем.The integrity of the proposed method is as follows.
Агломерированный или брикетироваииьп каолин в смеси с углеродистым восстановителем (антрацитом) и железной стружкой плав т в рудовосстановительной электропечи на электрокорунд и ферросилиций.Agglomerated or briquetted kaolin in a mixture with carbonaceous reducing agent (anthracite) and iron chips is melted in an ore reduction furnace for electrocorundum and ferrosilicon.
После окончани восстановительных процессов , о чем суд т по химическому составу штанговых проб электрокорунда, в печь подают магнезит (спекшийс или плавленный) из расчета иолучени в алюмомагнезиальном расплаве от 5 до 35 вес. /о MgO.After the completion of the reduction processes, as judged by the chemical composition of the rod samples of electrocorundum, magnesite (sintering or smelting) is fed into the furnace at the rate of 5–35 wt. / o MgO.
Алюмомагиезиальный расплав и ферросилиций выпускают из печи через отдельные метки с разностью уровней 300150 мм.Alumomagiesium melt and ferrosilicon are released from the furnace through separate labels with a level difference of 300,150 mm.
Получаема алюмомагнезиальна шнинель содержит не более 3,0 вес. ч/о примесей (SiOa, Ре2Оз, TiOs, СаО) и отличаетс однородностью по химическому составу.The resulting aluminum-magnesian shninel contains not more than 3.0 weight. h / a of impurities (SiOa, Fe2Oz, TiOs, CaO) and is characterized by homogeneity in chemical composition.
ДаннЕзп сиособ полученп алюмомагнезиальной шпинели осуществл ют в одном производственном цикле, что значительно упрощает технологию.This method of aluminum magnesia spinel is carried out in one production cycle, which greatly simplifies the technology.
