Optimization of Working Mass Composition for Dense Silica Bricks Production.
Maňák, Jan ; Lang,, Karel (referee) ; Nevřivová, Lenka (advisor)
A silica bricks is a refractory material which is used mainly in coke industry, glass industry and metallurgy. This material constitute of the quartz modifications. Compact silica is an irreplaceable part of the coke battery and its compactness and robustness is important for quality and long endurance. Very important for large compactness is a grain curve of work matter. This thesis deals with influence of different grain of work matter.

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.
