Description

Огнеупорные бетоны на основе портландцемента и глиноземистого цемента широко примен ютс  дл  футеровки различных тепловых агрегатов , топок, боровов, пода вагонов туннельных печей и других объектов.Refractory concrete based on Portland cement and alumina cement is widely used for lining various heat units, furnaces, boars, hearth car tunnel kilns and other objects.

Как известно, в случае применени  огнеупорного бетона дл  футеровки вагонов туннельных печей, отпадает предварительный обжиг, который осуществл етс  в услови х эксплуатации, а трудоемкие процессы укладки, тески и шлифовки штучных изделий замен ютс  механизированной укладкой подвижного бетона.As is well known, in the case of the use of refractory concrete for lining cars of tunnel kilns, preliminary calcination is eliminated, which is carried out under operating conditions, and labor-intensive processes of laying, grinding and grinding of piece goods are replaced by mechanized laying of mobile concrete.

По описываемому способу предлагаетс , в цел х снижени  коэффициента термического расширени  огнеупорного бетона и увеличени  оборачиваемости футеровки, приготовл ть его на основе глиноземистого цемента и кордиеритового спека, который получаетс  обжигом при 1300-1375° смеси, состо ший из: 1) огнеупорной глины (каолина ) и талька; 2) огнеупорной глины (каолина), талька и технического глинозема; 3) огнеупорной глины (каолина) и сырого магнезита .According to the described method, it is proposed, in order to reduce the thermal expansion coefficient of refractory concrete and increase the lining turnover, to prepare it on the basis of alumina cement and cordierite cake, which is obtained by calcining at 1300-1375 ° a mixture consisting of: 1) refractory clay (kaolin ) and talc; 2) refractory clay (kaolin), talc and technical alumina; 3) refractory clay (kaolin) and raw magnesite.

Эти смеси берутс  в соотношени х , близких стехиометрическому составу кордиерита.These mixtures are taken in ratios close to the stoichiometric composition of cordierite.

Кордиеритовый спек, в зависимости от вида примен емых материалов , их соотношени  и температуры обжига, имеет коэффициент термического расширени  1,0-2,5-10 в то врем  как шамотный или као .тиновый наполнитель имеет коэффициент 5,0-6,0- 10 - и выше.Cordierite sinter, depending on the type of materials used, their ratio and firing temperature, has a thermal expansion coefficient of 1.0-2.5-10, while the chamotte or caustic filler has a coefficient of 5.0-6.0- 10 - and higher.

Указанна  особенность кордиеритового спека значительно повышает срок службы огнеупорного бетона.This feature of cordierite cake significantly increases the service life of refractory concrete.

Предмет изобретени Subject invention

Способ получени  огнеупорного бетона на основе глиноземистого цемента и наполнителей, отличающийс  тем, что, в цел х увеличени  срока службы бетона, в качестве наполнител  примен ют кордиеритовый спек, имеющий коэффициент термического расширени  1,0-2.5- .A method for producing refractory concrete based on aluminous cement and fillers, characterized in that, in order to increase the service life of concrete, cordierite cake having a thermal expansion coefficient of 1.0-2.5 is used as a filler.
