Silica brick is a kind of acid refractory material consisting mainly of scale quartz, calcite and a small amount of residual
quartz and vitreous phase. Silica content in this brick is above 94%. True density 2.35g/cm3. It is resistant to acid slag. Higher high temperature strength. The initial temperature of load softening is 1620~1670℃. In high temperature for a long time without deformation. Low thermal shock stability (water heat exchange is 1~4 times) with natural silica as raw material, plus an appropriate amount of mineralization agent, to promote the conversion of quartz in the billet into, scale quartz. It is slowly fired at 1350~1430℃ in reducing atmosphere. When heated to 1450℃, about 1.5~2.2% of the total volume expansion, the residual expansion will make the cut joints close, to ensure that the masonry has good air tightness and structural strength.

An acidic refractory mainly composed of tridymite, cristobalite and a small amount of residual quartz and glass phase. The silica content is above 94%. The true density is 2.35g/cm3. It has resistance to acid slag erosion. Higher high temperature strength. The starting temperature of load softening is 1620～1670℃. It will not deform after long-term use at high temperature.

Low thermal shock stability. Natural silica is used as raw material, and an appropriate amount of mineralizer is added to promote the conversion of quartz in the body to tridymite. Slowly fired at 1350～1430℃ in a reducing atmosphere. When heated to 1450℃, there will be about 1.5~2.2% of the total volume expansion. This residual expansion will make the cut joints tightly and ensure that the masonry has good air tightness and structural strength.

not suitable for use on kilns with sudden temperature changes below 800°C. The true specific gravity is an important quality indicator of silica bricks, and high-quality silica bricks should be below 2.35. The true specific gravity is small, reflecting the large amount of tridymite and cristobalite in the brick, and the small amount of residual quartz, so the residual linear expansion is small, and the strength decline during use is also small.

Product Usage

Silica brick for glass furnace

Silica bricks for glass kilns refer to siliceous refractory products used in high temperature parts of glass kilns (not in contact with molten glass). The tank kiln is a large and complex masonry made of various refractory materials, and its vault mostly uses silica bricks. Some glass kilns also use silica bricks for the vault and checker bricks of the regenerator

Silica brick for hot blast furnace

(1) Under long-term high temperature and load conditions, the volume is stable, the high temperature creep rate is low, and it can be used continuously for one or two blast furnaces; (2) Good performance above 600℃ The thermal shock resistance. Adapt to the variability of the temperature of the hot blast stove, keep the bricks and masonry intact; (3) The chemical resistance is better than clay bricks and general high alumina bricks. (4) The thermal conductivity of silica bricks is larger than that of clay bricks and high alumina bricks, which is conducive to shorter Time to store and release heat.

Silica brick for coke oven

Silica bricks for coke ovens are mainly silica bricks, accounting for about 70% of the total refractory materials. It is the most suitable refractory brick for the furnace wall of the coking chamber. In the coking process, at the same time and with the same coal contact area, silica bricks can transfer more heat from the combustion chamber to the carbonization chamber, thus saving energy. The furnace wall itself also has a heat storage function.
