Description
Изобретение относитс к производству высокостойких огнеупорных покрытий , предназначенных до защиты керамических изделий, примен емых в агрегатах, используемых в черной и цветной металлургии.The invention relates to the production of highly resistant refractory coatings intended for the protection of ceramic products used in aggregates used in ferrous and non-ferrous metallurgy.
Цель изобретени - повышение огнеупорности при сохранении высокой термостойкости.The purpose of the invention is to increase the refractoriness while maintaining high heat resistance.
Покрытие готов т следующим образом .The coating is prepared as follows.
Диоксид циркони или бадделеитовый концентрат стабилизируют, например, одним из оксидов: CaO, MgO, Ti02, SiO в количестве от 2 до 9% путем обжига тонкодисперсных компонентов шихты при 1400-1750°С. Обожженный материал подвергают тонкому помолу, затем в пропеллерную мешалку загружают 200 г алюмохромфосфатной св зкиZirconium dioxide or baddeleite concentrate is stabilized, for example, with one of the oxides: CaO, MgO, Ti02, SiO in an amount of from 2 to 9% by roasting fine components of the charge at 1400-1750 ° C. The calcined material is subjected to fine grinding, then 200 g of aluminum-chromophosphate binder is loaded into the propeller agitator.
(АХФС) , 650 г цирконового концентрата и с интервалом 30 мин - 150 г стабилизированного двум процентами MgO диоксида циркони . Врем перемешивани 60 мин. шликера остальных составов готовили аналогично. Покрытие нанос т шликерным сливным методом на- шамотные кольца и затем производ т обжиг при 1400 С.(AHFS), 650 g of zircon concentrate and with an interval of 30 min - 150 g stabilized with two percent MgO zirconia. Mixing time 60 min. slips of the remaining compounds were prepared similarly. The coating is applied by a slip-slip method on our chambered rings and then fired at 1400 C.
Огнеупорность покрыти и термостойкость двухслойных изделий определ ли известной методикой.The refractoriness of the coating and the heat resistance of two-layer products were determined by a known technique.
