Their versatility and durability make silicon carbide refractories a preferred choice for industries facing extreme operating conditions.
The production of silicon carbide refractories involves several key steps:
High-purity quartz sand and petroleum coke are the primary raw materials. These are carefully selected and mixed in precise proportions to ensure the desired chemical composition.
The raw materials are loaded into an electric resistance furnace and heated to temperatures between 1800°C and 2800°C. This process, known as the Acheson process, results in the formation of silicon carbide crystals.
The silicon carbide crystals are crushed and graded into different particle sizes, depending on the intended application.
The graded silicon carbide is mixed with binders and shaped into bricks, plates, tubes, or custom components using pressing or casting methods.
The shaped products are sintered at high temperatures to achieve the desired density, strength, and microstructure.
The finished products are inspected for dimensional accuracy, mechanical strength, and chemical purity. Only products that meet stringent quality standards are shipped to customers.
China's silicon carbide refractory manufacturers are at the forefront of global innovation and supply, providing high-quality, cost-effective solutions to industries worldwide.
