Will the Spots on Silica Brick Surface Affect the Quality?
Not at all!
The main raw material of silica bricks has a high expansion coefficient. In order to ensure that the silica bricks do not crack during use, Kerui will ensure that its crystal form is completely transformed. The spots on the surface of the silica bricks we see are the residues after the crystal form is completely transformed. This has no effect on the quality of the product!

Introduction of Silica Refractory Brick Properties
Chemical Erosion Resistance
Due to its high-quality raw materials. Kerui silica bricks have good resistance to the erosion of acidic slag. Therefore, this product is suitable for kilns with strong acidic atmospheres, including glass kilns, coke ovens, hot blast furnaces, etc. Welcome to explore more info on Kerui LinkdeIn.
Good Thermal Vibration Stability
During the operation of high-temperature kilns, it is inevitable to face periodic temperature changes. Silica bricks can maintain a stable structure in the face of strong temperature changes, thereby extending the service life of the kiln.
High Temperature Volume Stability
Kerui silica bricks have a high load softening temperature. This also means that using silica bricks as kiln linings can well withstand the pressure of the furnace wall and furnace top without deformation. This high temperature volume stability is the key to maintaining the safety and stable operation of the kiln.
Main Uses of Silica Fire Brick
Coke Oven
Coke oven is mainly used for burning coal, and silica brick lining can withstand the acidic atmosphere and slag erosion. Usually customers use silica brick to build the heat storage chamber, ramp, combustion chamber, carbonization chamber and furnace roof of coke oven.
Hot Blast Furnace
Silica bricks are used to build the high-temperature parts of hot blast furnaces. With the continuous development of hot blast furnaces and the increase in wind temperature, traditional alumina bricks can no longer meet the demand. Silica bricks specially used for hot blast furnaces have better thermal shock resistance and chemical corrosion resistance.
Glass Kiln
The silica bricks for glass kilns are often used in vaults, breast walls, heat storage chambers, etc. In order to achieve good heat storage effect and high temperature resistance, silica checker bricks are also very common in glass kilns.
Other Common Uses of Silica Refractory Brick
Steel-making electric furnace, open hearth furnace, ceramic kiln, non-ferrous metal smelting furnace and other kilns that need to face strong acidic atmosphere corrosion. This product has excellent high temperature bearing performance.
