Изобретение относитс к области металлургии цветных металлов, в частности -к электролитическому Производству магн-и .This invention relates to the field of non-ferrous metallurgy, in particular to the electrolytic production of magnes.
Известны футеровки различны.х .металлургических аппаратов при электролитическом производстве магни , наа1ример футеровки электролизеров, включающие огиеупорную кладку, выполненную из различных материалов , таких каж магнезитовый, ма1рнезитохромитовый кирпич, крупноблочный жароупорный бетон и т. д. 1,2.Lining of various types of metallurgical equipment for electrolytic production of magnesium is known, for example, the lining of electrolysis cells, including fireproof masonry made of various materials, such as magnesite, metallic chromite brick, large-block refractory concrete, and so on. 1,2.
Аппараты дл :подготовки сырь перед электролитическим производство м магни также имеют аналогиЧнуЕО футеровку, содержащую огнеупорную кладку 3.Apparatus for: preparation of raw materials before electrolytic production; magnesium also has counterparts Lining containing refractory masonry 3.
Все металлургичеокие аппараты, содержащие огнеупорную футеровку, требуют сушки и разОГрева леред вводом их в работу после монтажа или капитального ремонта. Дл этого во всех известных алпаратах во внутреннем рабочем пространстве устанавливают переносные нагреватели, например спиральные или ленточные иихромовые. При этом сушка и прогрев футеровки происходит неравномерно , д.тительно во времени. За счет неравномерного прогрева 1Про«сходит растрескивание футеровки, при последующем вводе аппарата в работу футероока :быстро выходит из стро из-за попадани агрессивных расплавленных сред в образовавшиес трещины.All metallurgical equipment containing refractory lining, require drying and heating by putting them into operation after installation or overhaul. For this purpose, portable heaters, for example spiral or band and chromic heaters, are installed in all known devices in the internal working space. In this case, the drying and heating of the lining occurs unevenly, far in time. Due to the uneven heating of the 1Pro, the cracking of the lining is eliminated, with the subsequent introduction of the apparatus into the work of the luteocular: it quickly fails due to ingress of aggressive molten media into the cracks formed.
Предлагаема футеровка отличаетс тем, что в кладке р дами установлены нагревательные элементы, соответствующие по форме и размерам конфигура.ции «ладки.The proposed lining is characterized in that the masonry is installed in rows of heating elements that correspond in shape and size to the configuration of the ladder.
Эти отличи способствуют увеличению срока службы футеровки и сокращению пусконаладочного периода аппаратов.These differences help to increase the service life of the lining and reduce the commissioning period of the devices.
На фиг. 1 показана предлагаема футеровка в составе магниевого электролизера, поперечный разрез; на фиг. 2-разрез по А-А на фиг. d.FIG. 1 shows the proposed lining in the composition of the magnesium electrolyzer, a cross-section; in fig. 2 is a section along the line A-A in FIG. d.
Футеровка содержит огнеупорную кладку 1, заключенную в 2, с установленными в .нее р дами щагревательными элементами 3,The lining contains refractory masonry 1, enclosed in 2, with shaving elements 3 installed in the row,
соответствующими по размерам и форме конфигурании кладки. Нагревательные элементы установлены друг от друга на рассто нии, равном 1-3 .рассто ни м от нагревательных элементов до внутренней поверхности кладки.corresponding in size and shape of the masonry configuration. The heating elements are set apart from each other at a distance equal to 1-3 times the distance from the heating elements to the inner surface of the masonry.
Нагревательные элементы за.ка чиваютс распределител ми тока 4 с токоподвода.ми. 5.The heating elements are buried in the current distributors 4 with the current lead. five.
Тепло, выдел емое нагревательными элементами , будет повышать температуру огнеупорной кладки. Первоначально прогреваютс The heat generated by the heating elements will increase the temperature of the refractory masonry. Initially warmed up
