Description
спирта и серной кислоты и пе мещивают в тече ние 1 2 мин. При непрерывном перемешивании раствора маршалит загружают небольшими порци ми. Врем перемешивани 3-5 мин. Затем вливают питьевую воду, подкисленную сол ной кислотой, и 1фодЬлжают реремеш1шание в течение 40 - 45 мир, пос-;alcohol and sulfuric acid and leave for 1 2 minutes. With continuous stirring, the marshalite solution is loaded in small portions. Mixing time 3-5 min. Then, drinking water, acidified with hydrochloric acid, is poured in, and the mixture is stirred for 40-45 peace, after;

в суспензию ввод т криолит, и суспензию дополнительно перемешивают 2 - 3 мин. Cryolite is introduced into the suspension, and the suspension is additionally stirred for 2–3 minutes.
Результаты испытани образцов на прочность, изготовленных с различным содержанием криолита в огнеупорной суспензии в непрокаленном и прокаленном состо нии, приведены в таблице.The results of testing the strength of specimens made with different contents of cryolite in the refractory suspension in the non-calcined and calcined state are shown in the table.
Таким образом, оптимальным содержанием крио- лита в суспензии вл етс 4,3 %, и оптимальным вл етс следующий состав суспензии, вес. %: Огнеупорный наполнитель65,2Thus, the optimum content of cryolite in suspension is 4.3%, and the following composition of suspension is optimal, weight. %: Refractory filler65,2

На чертеже представлен график зависимости прочности образцов, изготовленных из суспензий с различным содержанием в них криолита, из которого следует , что с повышением содержани криолита в суспензии выше за вленного диапазона прочность форм как в сыром, так и в прокаленном состо нии падает.The drawing shows a plot of the strength of samples made from suspensions with different contents of cryolite in them, from which it follows that with an increase in the content of cryolite in suspension above the stated range, the strength of the forms in the raw and calcined state decreases.
