Description

Дл  тсплоизол  1ии высокотемпературных объектов примен ютс  издели  из огнеупорных материалов , полученные путем введени  выгорающих дсбавок или пены.For high-temperature objects, high-temperature objects are made of refractory materials obtained by adding burnable additives or foams.

Однако в том и другом случае получаемые издели  имеют малую механическую прочность, вследствие чего не представл етс  возможным дл  широкого применени  изготовл ть теплоизол ционные огнеупоры объемным весом менее 700- 800 кг;м.However, in either case, the resulting products have low mechanical strength, as a result of which it is not possible for widespread use to produce heat-insulating refractories with a bulk weight less than 700-800 kg; m.

Насто щим изобретением предлагаетс  способ получени  теплоизол ционных огнеупорных изделий  чеистого строени , более высокой прочности и с мизкпм объемным весом.The present invention proposes a method for producing heat insulating refractory products of a cellular structure, of higher strength and with a minimum bulk weight.

В качестве исходного сырь  используетс  огнеупорна  глина или каолпп, содержащие слюды (мусковит , биотит), гидрослюды или амфиболы (актиполит, тремолит, роговую обманку) с добавлением к ним окиси магни  в количестве от 5 до 15%.As a raw material, refractory clay or kaolpp is used, containing mica (muscovite, biotite), hydromica or amphibole (actipole, tremolite, hornblende) with addition of magnesium oxide in the amount of 5 to 15%.

Взамен окиси магни  примен тьс  сырой магнезит, доломитInstead of magnesia, raw magnesite and dolomite are used.

п т. п. горные породы, содержащие соответствующее количество окиси магни .pp rocks containing an appropriate amount of magnesium oxide.

Из сырьевой смеси изготовл ютс  брикеты, которые подвергаютс  обжигу при температурах, завис щих от требуемой огнеупорности окончательного продукта и наход щихс  в пределах от 1150 до 1300°.Briquettes are made from the raw material mixture, which are calcined at temperatures that depend on the required refractoriness of the final product and range from 1150 to 1300 °.

Б результате обжига изделие из огнеупорной глины вспучиваетс , принил1а  округлуЕО форму, либо форму того сосуда, в котором оно обжигаетс .As a result of firing, the refractory clay product is expanded, forming a round shape or the shape of the vessel in which it is fired.

В первом случае получаютс  те.ча окатанной формы, которые можно примен ть в качестве легкого огнеупорного заполнител , а во втором- огнеупорные легкие блоки правильной формы, которые можно примен ть д.т  к.чадки стен и теп .юзащитпых конструкций объектов с рабочей температурой 1150-1200° и выще.In the first case, te.ch of rounded shape is obtained, which can be used as a light refractory aggregate, and in the second, refractory light blocks of a regular shape, which can be used at the walls and heat protection structures of the objects with a working temperature. 1150-1200 ° and above.
