Fireclay Grog with a High Alumina Content
Mezulianík, Tomáš ; Tvrdík,, Lukáš (referee) ; Nevřivová, Lenka (advisor)
Special refractory grog with increased alumina content are not currently produced in the Czech Republic. The price of these grogs produced abroad is high, so there is an effort to produce grogs using domestic waste fractions of claystones, which have been stored for decades. The theoretical part of the thesis describes the current results and experience with the processing of fine waste parts of claystone W super and BVP. Suitable raw materials for the preparation of grog with an increased content of alumina are characterized. In the experimental part of the thesis is verified the possibility of production of grogs with increased content of Al2O3 according to the proposed prescriptions.

Technological Possibilities of Using Waste Claystone for Manufacturing Refractory Grog burned in blast furnaces
Konečný, Martin ; Tvrdík,, Lukáš (referee) ; Nevřivová, Lenka (advisor)
Aluminosilicate refractory grog are being manufactured by firing refractory clays, claystone and shale. Firing takes place mainly in rotary or blast furnaces. However, when adjusting the raw material before firing in blast furnaces, the formation of the fine clay particles takes place. It is not possible to fire the fine particles in blast furnaces the usual way, which leads to the generation of waste. There is a possibility, however, to form briquettes of these particles, which can be fired in blast furnaces. This solution also brings the possibility of adjusting the mixture by using correction raw materials or other types of clay. Using this method, it is possible to produce a special refractory grog with specific properties.
