Conclusions
In the department making high-alumina products at the Zaporozh'e Refractories factory they have manufactured an experimental-industrial batch of refractories with high thermal properties for building high-temperature zones of air heaters.
The properties of the articles can be improved by fitting the department with powerful presses with staged pressing cycles.
In the preparation of articles with a content of not less than 50% Al2O3+TiO2 with a high-alumina bond, an effective method is to introduce commercial alumina together with fine grinding of the components. With this technology there is no need to prepare high-alumina grog which has to be crushed and ground.
When organizing the industrial production of high-alumina articles using the proposed technology it is necessary to instal hydraulic presses with staged pressing with forces of not less than 1000 tons of powerful automatic friction presses, batching feeders, mixers SM-568, ensuring necessary vacuum treatment of the bodies, and high-temperature tunnel kilns with low settings.
