What do the technical parameters of refractory bricks represent: refractoriness, load softening temperature, sintering temperature.
Fracture resistance refers to the ability of refractory materials to maintain their structural integrity and chemical stability at high temperatures. The load softening temperature refers the temperature at which a material begins to deform and flow under a given load. The sintering temperature refers to the lowest temperature at which chemical reactions occur between the particles of a material during the process of pressing it into a solid material at a certain temperature. These three concept

Study on the Alkali Corrosion Resistance of Aluminum Silicon Refractory Bricks Used in Cement Kilns
Currently, in the low-temperature zone of cement rotary kilns, the use of aluminum-silicon products such as series silica-mullite bricks, anti-spalling high-alumina bricks, and new low-alumina mullite bricks exhibits significant differences in raw material selection and physicochemical properties. In this study, we compared the alkali resistance of these different products and analyzed their microstructure and phase composition to evaluate their alkali resistance. This, in turn, will optimize t

What is the relationship between refractory temperature and alumina content of high alumina bricks
There is a positive correlation between the refractory temperature and alumina content of high alumina bricks. The higher the alumina content of high alumina bricks, the higher their refractory temperature. However, in actual use, other factors such as production process, material impurities, and usage environment also need to be considered. Therefore, when choosing high alumina bricks, it is necessary to comprehensively consider the specific usage needs and conditions and select suitable produc
