In this article, the critical parameters of silica refractories, such as compressive strength, bulk, density, quantity of the silica, microstructure and porosity, were evaluated.Abstract:
The critical parameters of silica refractories, such as compressive strength,
bulk, density, quantity of silica, microstructure and porosity were evaluated
of unused and used bricks to line the crowns of glass furnaces, when the rate
of corrosion of crowns were about 2 times greater. The change of these
parameters, the chemical composition and formation of the microcracks in the
used silica refractories material were studied. It was established that the
short time at service of container glass furnace crown can be related to low
quality of silica brick: high quantity of CaO and impurities, low quantity of
silica, low quantity of silica, transferred to tridymite and cristobalite and
formation of 5-10 μm and more than 100 μm cracks in the crown material. The
main reason of corrosion high quality silica bricks used to line the crown of
electrovacuum glass furnace is the multiple cyclic change of crown
temperature at 1405 - 1430°C range in the initial zone of crown and at 1575 -
1605°C range in the zone of highest temperatures.read more
