Industry Background and Pain Points in Refractory Material Requirements

In the high - temperature industrial sectors such as non - ferrous mines, metallurgical blast furnaces, and the ceramic industry, the demand for high - performance refractory materials is ever - increasing. Traditional refractory materials often face challenges like low strength, poor thermal conductivity, and weak thermal shock resistance under extreme high - temperature conditions. For example, in non - ferrous mines, the high - temperature environment can cause the rapid deterioration of ordinary refractory bricks, leading to frequent replacement and high maintenance costs. According to independent laboratory data, some traditional refractory materials may lose up to 30% of their strength after being exposed to high temperatures above 1200°C for 100 hours.

Core Performance of Nitride - Bonded Silicon Carbide Bricks

Strength

Nitride - bonded silicon carbide bricks have excellent strength. Independent laboratory tests show that their compressive strength can reach up to 150 MPa, which is much higher than that of many traditional refractory materials. This high strength enables the bricks to withstand greater pressure in high - temperature industrial environments, reducing the risk of breakage and deformation.

Thermal Conductivity

With good thermal conductivity, the bricks can quickly transfer heat, which helps to maintain a stable temperature distribution in industrial furnaces. The thermal conductivity of nitride - bonded silicon carbide bricks can reach about 20 W/(m·K), which is significantly better than some common refractory bricks with a thermal conductivity of only 5 - 10 W/(m·K). This feature greatly improves the energy - efficiency of industrial production processes.

Thermal Shock Resistance

One of the most remarkable features of these bricks is their outstanding thermal shock resistance. They can withstand rapid temperature changes without cracking or spalling. In a test, nitride - bonded silicon carbide bricks were heated to 1400°C and then rapidly cooled to room temperature for 100 cycles, and only showed less than 5% damage, while traditional refractory materials often failed after 20 - 30 cycles.

Multi - Industry Specific Applications

Non - Ferrous Mines

In non - ferrous mines, the high - temperature smelting process requires refractory materials with high strength and thermal shock resistance. A well - known non - ferrous mining company in South America replaced their traditional refractory bricks with nitride - bonded silicon carbide bricks. After one year of use, they found that the replacement frequency of refractory materials decreased by 60%, and the production efficiency increased by 15% due to the more stable furnace environment.

Metallurgical Blast Furnaces

In metallurgical blast furnaces, the high - temperature and high - pressure environment demands refractory materials with excellent thermal conductivity and strength. A large - scale steel plant in Europe adopted nitride - bonded silicon carbide bricks for the lining of their blast furnaces. As a result, the energy consumption per ton of steel decreased by 8%, and the service life of the furnace lining was extended by 2 - 3 years.

Ceramic Industry

In the ceramic industry, the firing process requires precise temperature control. The high thermal conductivity of nitride - bonded silicon carbide bricks ensures uniform temperature distribution in the kiln, improving the quality of ceramic products. A ceramic manufacturer in Asia reported that after using these bricks, the defective rate of their products decreased from 10% to 3%.
