Silicon nitride bonded silicon carbide bricks have emerged as a cornerstone product in the refractory materials industry, playing a crucial role in non - ferrous mines, metallurgical blast furnaces, and the ceramic industry. In non - ferrous mines, these bricks can withstand the harsh environment of high - temperature ore smelting. In metallurgical blast furnaces, they ensure stable operation under extreme conditions. And in the ceramic industry, they contribute to the high - quality firing process of ceramic products.
According to a third - party testing report, the compressive strength of silicon nitride bonded silicon carbide bricks can reach up to 500 MPa, which is significantly higher than many traditional refractory materials. This high strength allows the bricks to bear heavy loads in high - pressure environments such as blast furnaces without deformation, ensuring the long - term stability of the equipment.
The thermal conductivity of these bricks is as high as 20 - 30 W/(m·K). This excellent thermal conductivity enables rapid heat transfer in the furnace, which helps to maintain a uniform temperature distribution in the furnace, improving the efficiency of the smelting or firing process and reducing energy consumption.
Silicon nitride bonded silicon carbide bricks can withstand rapid temperature changes without cracking. Tests show that they can endure temperature differences of up to 1000°C without significant damage. This property is crucial in industries where frequent heating and cooling cycles occur, such as the ceramic industry and some metallurgical processes.
One of the most outstanding features of these bricks is their strong resistance to chemical erosion. In contact with highly corrosive substances such as molten metals and slags, the erosion rate is less than 1% per year. This greatly extends the service life of the equipment and reduces maintenance costs.
Silicon nitride bonded silicon carbide bricks have gained wide recognition in the international market. More than ten well - known overseas enterprises have chosen these bricks for their production needs. Approximately 80% of the production volume is exported to regions such as Europe and America. This high export ratio indicates the high - quality and competitiveness of the product in the global market.
Let's take a certain smelter as an example. After using silicon nitride bonded silicon carbide bricks, the service life of the furnace has been extended by 30%. This not only reduces the frequency of furnace repairs and replacements but also significantly improves the production efficiency of the smelter. Another example is a ceramic factory. By using these bricks in the kiln, the quality of the ceramic products has been improved, and the energy consumption has been reduced by 20%.
Silicon nitride bonded silicon carbide bricks offer a high - performance solution for industries in need of reliable refractory materials. They can make your equipment more durable and run more stably. Choosing them means choosing long - term cost optimization.
