China Zircon-Mullite Checker-work Suppliers - High-Performance Refractory Brick from Reliable Factory
Features
1. High refractoriness
Zircon mullite itself has a high melting point and excellent high-temperature resistance. It can withstand high-temperature environments, and is not easy to melt or deform at high temperatures. It can maintain a stable structure in industrial furnaces and other environments at temperatures of 1600°C or even higher.
2. Good chemical stability
It has good resistance to chemical substances such as acidic and alkaline slags, and is not prone to chemical reactions with these substances. It can effectively resist the erosion of various chemical substances and prolong its service life.
3. High mechanical strength
It has high compressive strength and flexural strength, and can withstand the pressure of materials in the furnace and mechanical forces such as thermal stress. It is not easy to break or be damaged, ensuring the integrity of the checker-work structure.
4. Low thermal conductivity
It has a low thermal conductivity, which can effectively reduce heat transfer, play a good role in heat insulation and heat preservation, improve thermal efficiency, and reduce energy consumption.
5. Good thermal shock stability
In the case of rapid temperature changes, such as during the startup and shutdown of the furnace, it can resist the impact of thermal stress and is not prone to phenomena such as cracking and spalling, and has good thermal shock stability.
6. Excellent heat storage
As a checker-work structure, it has a large specific surface area and a reasonable pore structure, which can quickly absorb and release heat, achieve efficient heat storage and heat transfer, and improve the heat exchange efficiency of the furnace.
