Silica brick is a type of refractory brick made from silica or silicon dioxide, a mineral found in abundance in nature. It has high-temperature strength and excellent thermal shock resistance, making it ideal for use in various high-temperature industrial applications. Here are some common uses of silica brick:
1.Glassmaking industry: Silica brick is widely used in the glassmaking industry, particularly in the construction of glass melting furnaces. The high thermal conductivity and low thermal expansion of silica brick allow it to withstand extreme temperature fluctuations during the melting process.
2.Coke oven industry: Silica brick is also used in the coke oven industry, where it provides excellent resistance to high temperatures and corrosive gases. It is commonly used in the lining of coke oven walls, roofs, and combustion chambers.
3.Petrochemical industry: Silica brick is highly resistant to acid and alkali corrosion and is therefore used in the petrochemical industry for lining reactors, distillation towers, and other high-temperature equipment.
4.Steelmaking industry: Silica brick is used in the steelmaking industry for lining the hot blast stoves, which are used to preheat air before it is blown into the blast furnace. The high-temperature stability and thermal shock resistance of silica brick make it an ideal material for this application.
5.Other applications: Silica brick can also be used in various other high-temperature applications, such as in the lining of cement kilns, incinerators, and boilers.
Overall, silica brick is a versatile and reliable refractory material that provides excellent performance in high-temperature environments. Its ability to withstand thermal shock and chemical corrosion makes it an essential component in various industrial processes.
