(54) ШИХТА ДЛЯ ИЗГОТОВЛЕНИЯ ОГНЕУПОРНОГО МАТЕРИАЛА(54) CHARGE PREPARATION FOR PRODUCTION OF REFRACTORY MATERIAL
1one
Изобретение относитс к высокотемпературным материалам и может быть использовано в технике высоких температур.This invention relates to high temperature materials and can be used in high temperature engineering.
Известны шихтовые составы дл получени материалов, используемых в качестве огнеупорного и содержащие нитрид бора и добавку 1-10% окиси алюмини и 5-20% алюмохромфосфатного св зующего 1.Batch compounds are known for producing materials used as refractory and containing boron nitride and the addition of 1-10% alumina and 5-20% aluminum-chromophosphate binder 1.
Наиболее близким техническим решением к изобретению вл етс , щихта дл изготовлени огнеупорного материала на основе нитрида бора, содержаща , кроме- того, мас.%: оксид алюмини 1-10; нитрид алюмини 30-50 и алюмохромфосфатное св зующее (АХФС) 5-25 2.The closest technical solution to the invention is to prepare for the manufacture of a refractory material based on boron nitride, containing, in addition, wt.%: Aluminum oxide 1-10; aluminum nitride 30-50 and alumochromophosphate binder (AHFS) 5-25 2.
Недостатком материалов, полученных из указанных щихт, вл етс низка стойкость в кислых средых и относительно высока температура обжига - 800° С.The disadvantage of the materials obtained from the mentioned compounds is low resistance in acidic media and relatively high firing temperature - 800 ° C.
Целью изобретени вл етс повыщение стойкости материала в кислых средах и снижение температуры обжига.The aim of the invention is to increase the durability of the material in acidic environments and reduce the firing temperature.
Поставленна цель достигаетс тем, что шихта дл изготовлени огнеупорного материала , включающа нитрид бора, нитрид алюмини , и св зующее, дополнительно содержит окись кремни , а в качестве св зующего - основной хлорид алюмини Alj (ОН) sCI при следующем соотиопюнии компонентов, вес.%:This goal is achieved by the fact that the mixture for the manufacture of refractory material, including boron nitride, aluminum nitride, and binder, additionally contains silicon oxide, and as a binder, the main aluminum chloride Alj (OH) sCI with the following components, wt.% :
Нитрид алюмини 20-30Aluminum nitride 20-30

Дл получени огнеупорного материала готов т смеси на основе указанных компонентов , вз тых в требуемом соотношении.To obtain a refractory material, mixtures are prepared on the basis of the indicated components, taken in the required ratio.
Указанные смеси прессуют под давлением These mixtures are pressed under pressure
15 1 т/см производ т сушку заготовки в термическом шкафу при нагреве от 20 до 600° С со скоростью 1 град/мин (при температуре выдерживают 1 ч).15 1 t / cm, the billet is dried in a thermal cabinet with heating from 20 to 600 ° C at a rate of 1 deg / min (1 hour at a temperature).
Количество св зующего не должно пре20 вышать 30 мас.%, таре как в противном случае шихта плохо прессуетс . При содержании св зующего менее 15 мае. % наблюдаетс снижение прочности.The amount of the binder should not exceed 30% by weight, as the container would otherwise not compress well. When the content of the binder is less than 15 May. % a decrease in strength is observed.
