Description
Известен снособ изготовлени легкогб запЬлнител ; например керамзита, путем опудривани глинистых гранул алк минийсодержащиМ порошком и последующего их обжигЁ.A known method of making lightweight filler; for example, expanded clay, by dusting clay granules with an aluminum powder and then burning them.
Целью H3o6peteHHH вл efcй новь1шение hpp4HOctrt и огнеупорности заполнител .The aim of the H3o6peteHHH is the hpp4HOctrt innovation and fire resistance.
Это достигаетс тем, qto глинистЫе гр&нулы опудрйвакэт порош ком ш.г1аков вторичного переплава алюминиевых сплавоЁ.This is achieved by the fact that qto clay grades of powder are powdered with aluminum alloy re-melting.
Свежие отвальные шлаки алюминиевых Сплавов содержат 30-35 дисперсного металлического алюмини , 30-35% окиси алюмини АЬОз, 20-25% солей NaCl и КС1 и незначительное количество примесей MgO, SiOa, Ре2Оз и другие,Fresh dump slags of aluminum Alloys contain 30-35 dispersed metallic aluminum, 30-35% of aluminum oxide ABOz, 20-25% of salts of NaCl and KC1 and a small amount of impurities MgO, SiOa, Fe2Oz and others,
Опудренные этим шлаком, измельченным до удельной поверхности 4500-5000 CAf-jz, сырьевые глинистые гранулы обжигают при температуре 1250-1275°С до вспучивани .Powdered with this slag, crushed to a specific surface of 4500-5000 CAf-jz, the raw clay granules are calcined at a temperature of 1250-1275 ° C until swelling.
Тонкодисперсный алюминиевый порошок, содержащийс в шлаковой (нудре, сгорает на поверхности гранул, превраш,а сь в АЬО.з. При этом выдел етс большое количествоThe fine aluminum powder contained in the slag (nudra burns on the surface of the granules, turning into ABO.W. In this case, a large amount of
JJ
тенла и температура на поверхности грану.г1 достигает 1520-1600°С.tenla and the temperature on the surface of granu reaches 1520-1600 ° C.
Флюсовые соли (NaCi, КСЦ NasAlFe); со держащиес в , понижают температуру спекани минералов глины с AUOs шлака и сами в процессе обжига полностью улетуФгваЮтс .Flux salts (NaCi, NasAlFe SCS); Contained in, lower the temperature of sintering clay minerals with slag AUOs themselves and in the firing process completely fly away.
В результате снеканий на nobepxiloctH легкого заполнител образуетс корочка состо ща из муллита (ЗА1оОз-23 02) и небольшого количества глиноземистой шпинели (MgA104).As a result of sniping on nobepxiloctH of a lightweight aggregate, a crust consisting of mullite (ZA10-O2 02 02) and a small amount of alumina spinel (MgA104) is formed.
Предмет изобретени Subject invention
Способ изготовлени легкого занолнител , например керамзита, путем опудривани глинистых гранул алюминийсодержащим порошком и последующего их обжига, отличающийс тем, что, с целью повышени прочности и огнеупорности занолнител , глинистые гранулы опудривают порошком шлаков вторичного переплава алюминиевых сплавов.A method for manufacturing lightweight solvents, such as expanded clay, by dusting clay granules with an aluminum-containing powder and then calcining them, characterized in that, in order to increase the strength and refractoriness of the solvent, the clay granules are powdered with a powder of slag of secondary melting of aluminum alloys.
