Description
Известные способы изготовлени огнеупорното раствора на основе тонкомолотого магнезитового порошка, затворенного раствором сернокислого магни с применением в качестве зернистого наполнител магнезита или хромита не обеспечивают требуемых- прочности и плотности шва при необходимых температурах.The known methods for the manufacture of a refractory solution based on finely ground magnesite powder, shuttered with a solution of magnesium sulphate using magnesite or chromite as a granular filler do not provide the required strength and density of the seam at the required temperatures.
Предлагаемый способ изготовлени высокоогнеупорного цементного раствора обеспечивает прочность и огнеупорность раствора и изделий «а его основе.The proposed method of manufacturing high-refractory cement mortar provides strength and refractoriness of the solution and products to its base.
Это дОСтигаетс одновременным введением в раствор молотой чугунной стружки фракции до 2 мм.This can be achieved by simultaneously introducing a fraction of up to 2 mm into the solution of ground cast iron shavings.
При низких те:М1пературах тонкомолотый магнезитовый порошок взаимодействует с сернокислым магнием, обеспечива высокую прочность шва кладки до температуры разложени оксисульфатов магни . При разложении последних выдел етс серный ангидрид, который окисл ет чугунную стружку, а 1выдел юш.иес при этом окислы железа взаимодействуют с окисью магни , образу высокоогнеупорные твердые растворы.At low temperatures: Finely ground magnesite powder interacts with magnesium sulphate, providing high strength of the masonry seam to the decomposition temperature of magnesium oxysulfate. During the decomposition of the latter, sulfuric anhydride is released, which oxidizes pig iron chips, and in this case, iron oxides react with magnesium oxide to form highly refractory solid solutions.
Эта реакци ороисходит с уменьшением удельного веса и соответственно с увеличением удельного объема, что дает уплотнение шва, исключа его растрескивание.This reaction occurs with a decrease in specific gravity and, accordingly, with an increase in specific volume, which gives a seal to the seam, excluding its cracking.
В таблице приведены примерные составы -цементных высокоогнеупорных растворов при различной основности шлаков.The table shows the approximate composition of cement-high-refractory mortars with different basic slags.
