Electric melting zirconia corundum refractory brick, commonly known as AZS brick, is a type of high-grade refractory material used primarily in glass kilns and steelmaking furnaces. AZS brick is known for its excellent resistance to corrosion, thermal shock resistance, and high-temperature durability, making it an essential material in many industrial processes.
The electric melting process used to create AZS brick ensures that the material has uniform properties throughout, resulting in a durable and reliable product. The unique combination of alumina, zirconia, and silica creates a structure with very few open pores, making AZS brick resistant to chemical attacks from molten glass and steel.
AZS brick can withstand temperatures in excess of 2000°C and is also highly resistant to thermal shock. This property is crucial in glass kilns as the rapid changes in temperature can cause other types of refractory materials to crack and fail. The use of AZS brick ensures that glass manufacturing processes run without interruption, maintaining efficiency and reducing downtime.
AZS brick is also a popular choice in the steelmaking industry. The corrosion-resistant properties of AZS brick make it ideal for use in the steel ladle, where it can withstand high-temperature molten steel without cracking or eroding. The use of AZS brick in steel furnaces and ladles reduces maintenance costs and increases the lifespan of furnace linings.
Overall, the use of electric melting zirconia corundum refractory brick (AZS brick) is essential in many industrial processes. Its excellent resistance to corrosion, thermal shock resistance, and high-temperature durability make it a reliable and cost-effective material. As industries continue to demand higher levels of performance, the use of AZS brick will undoubtedly increase in popularity.
