High-quality Components of Silica Refractory Bricks

Ronghua silica refractory brick is a refractory brick with high-quality silicon dioxide as the main component. This brick is made from natural silica stone as raw material. It adds a suitable amount of mineralizer and is fired at 1350-1430ºC.

After firing, the mineral composition of the silicon bricks changes. It mainly consists of cristobalite, tridymite, residual quartz, diopside, glass phase, and so on. The mineralizer (lime milk) promotes the formation of the scale quartz phase. Therefore, bricks have spots on them.

Other Shapes of Silica Bricks

In addition to standard straight bricks, we also offer bricks in a variety of shapes, including special-shaped bricks, checkered bricks, ax bricks, anchor bricks, composite bricks, universal arc bricks, curved bricks, and so on.

Properties of Silica Bricks

High Temperature Stability

The high load softening temperature of silicon brick reaches 1640-1670ºC. The stability of volume change ensures that it maintains its structural integrity and performance under extreme high-temperature conditions.

Acid Slag Erosion Resistance

The acid resistance and slag erosion resistance of silicon brick protect it from chemical corrosion in environments with acidic or corrosive substances, for example, CaO、FeO、Fe2O3, and other oxides. It is different from mag carbon bricks.

Low Thermal Conductivity

The low thermal conductivity of silicon brick helps maintain consistent temperatures within the structure. The silica refractory brick properties can improve energy efficiency and overall performance while also resisting thermal shock.

High Gas Tightness

The high gas tightness of silicon brick helps maintain the required atmosphere within the structure. It ensures efficient operation and excellent performance of industrial kilns. This is crucial for safety and efficiency in high-temperature and high-pressure kiln environments.

Note: 1. Silicon bricks are not suitable for alkaline working environments. They are easily damaged by oxides containing Al2O3, K2O, and Na2O.
2. They are not suitable for working in environments below 800 degrees Celsius because of poor earthquake resistance. Below 800 degrees Celsius, the furnace needs to be slowly heated and cooled.

Applications of Silica Fire Brick

Glass Furnace

A large number of silicon bricks are commonly used in the construction of glass furnace arches, glass melting pots, glass furnace walls, and kiln roofs. Its application in glass furnaces offers the following advantages: strong resistance to acid slag erosion, strong thermal shock resistance, stable volume at high temperatures, and so on.

Coke Oven

In coke ovens, silicon bricks are typically used in carbonization chambers, combustion chambers, walls, heat storage chambers, and chutes, among others. Silicon bricks provide certain irreplaceable advantages for continuous production coke ovens, such as high load softening temperature, strong thermal shock resistance, low thermal conductivity, strong resistance to acid slag erosion, and so on.

Hot Blast Stove

Silicon bricks are commonly used in the walls and arches of hot blast stoves. This is because silicon bricks can maintain stable volume at high temperatures in hot blast stoves. They resist the erosion of acidic substances and maintain consistent temperature with the furnace interior. They are an ideal choice for maintaining the integrity of hot blast stove structures.

Acid Steelmaking Converter

A large number of silicon bricks are used in the heat storage chamber and slag chamber of acid steelmaking converters. Due to their excellent acid resistance and high load softening temperature, silicon bricks can maintain stable structure and performance in acid steelmaking converters, helping equipment to operate stably over the long term.
