silicon carbide-based refractories
Oxide-bonded silicon carbide (SiC) is a type of refractory material formed by bonding SiC grains with a silica-based oxide matrix. It offers excellent abrasion resistance, moderate thermal shock resistance, and good corrosion resistance, especially in oxidizing atmospheres. It is commonly used in kiln furniture, furnace linings, and thermal processing equipment due to its durability and cost-effectiveness.
Nitride-bonded silicon carbide (NBSC) is a high-performance refractory material formed by bonding silicon carbide grains with silicon nitride (Si₃N₄). Known for its exceptional thermal shock resistance, high mechanical strength, and excellent wear and corrosion resistance. Its durability makes it ideal for demanding environments such as incinerators, kilns, and cyclone burners, particularly where exposure to slag and chemical attack is common.
Boinex-ref has extensive experience in designing refractory products for various waste-to-energy boiler lining systems, ranging from older generations to the latest state-of-the-art solutions.
Boinex-ref has demonstrated excellent results in determining the oxidation resistance of shaped refractory SiC bricks under steam atmosphere at 1000°C for 500 hours. According to ASTM C 863-83, their materials show exceptional durability and resistance to oxidation, confirming their high-performance capabilities in extreme environments. These results highlight Boinex’s commitment to delivering top-quality, long-lasting refractory solutions for demanding industrial applications.
Raw materials are meticulously selected and blended to create the ideal refractory composition. This ensures consistency and optimal material properties for the end product.
The mixture is carefully shaped into the required forms using precise molding techniques. This stage ensures that each product meets the exact specifications for performance and design.
haped products undergo a controlled drying process to eliminate moisture, ensuring no structural compromises. This step is crucial for avoiding defects and preparing the material for firing.
The final stage involves firing the products at high temperatures in specialized kilns to solidify their properties and ensure exceptional durability for industrial use. The controlled firing process enhances the material's resistance to thermal shock and wear.
As Director of Boinex-ref, it’s an honor to lead a dedicated team focused on developing high-performance refractory solutions for the waste-to-energy sector and other demanding applications.
