Product Details
NSiC Fire Bricks for Sale
Fireramo NSiC bricks are high-performance refractory materials made of high-quality silicon carbide (SiC) and silicon nitride (Si3N4) as the main components, prepared through precise batching and special technology. Fireramo NSiC bricks SiC content ≥ 72%, Si3N4 content ≥ 18%, the total content of the two ≥ 94%, and at the same time, strict control of the impurity content of Fe2O3 ≤ 0.7%, to ensure that the excellent performance and stability of the product. excellent performance and stability of the product.
Fireramo NSiC brick features
High-temperature resistance: NSiC bricks can withstand the highest hot surface temperature up to 1650°C, with excellent high-temperature oxidation resistance and thermal shock resistance.
High mechanical strength: Whether at room temperature or in a high-temperature environment, NSiC bricks have excellent mechanical properties, with a cold modulus of rupture of ≥40MPa, modulus of rupture of ≥45MPa, and ≥42MPa at 1400℃ and 1000℃, respectively, and cold compression strength of ≥150MPa, which ensures the strength and stability of the bricks under extreme working conditions.
High density and low porosity: bulk density ≥2.65g/cm³, porosity ≤17%, which effectively reduces the heat conduction loss and improves the refractory and heat insulation performance.
Excellent thermal stability: NSiC brick thermal expansion rate in the range of 20-1400 ℃ ≤ 4.8 × 10-6, showing a very low coefficient of thermal expansion, which greatly reduces the deformation of the brick body caused by temperature changes.
Efficient thermal conductivity: NSiC bricks have a thermal conductivity of ≥16W/(m-K), which is conducive to the rapid transfer of heat and improves the efficiency of the kiln.
Fireramo NSiC Brick Applications
NSiC bricks are widely used in high-temperature equipment and kilns in metallurgy, the chemical industry, ceramics, glass, energy, and other industries, such as iron and steel smelting furnaces, non-ferrous metallurgy furnaces, glass melting pools, chemical reactor and other high-temperature linings and key parts, especially suitable for scenes with strict requirements on high-temperature performance, mechanical strength and thermal stability of refractory materials.
