SK 40 alumina refractory bricks are versatile and durable materials designed for high-temperature applications. Derived primarily from alumina-rich sources like bauxite, these bricks are meticulously crafted through a multi-step process.
Raw materials are meticulously selected and blended, including additives for specific properties. The resulting mixture is shaped into brick forms, often via pressing or extrusion. Careful drying prevents deformities. The bricks are then subjected to high-temperature firing, or sintering, exceeding 1300°C to induce crucial chemical and physical changes.
Related to Process
The primary raw material used in alumina refractory bricks is alumina, typically derived from bauxite ore. Other materials, such as clays, silica, and various additives, may also be included to achieve specific properties. The raw materials are carefully selected and blended to achieve the desired chemical composition.
The blended raw materials are mixed to create a uniform mixture. Water may be added to form a plastic or semi-plastic mass. This mixture is then shaped into brick forms using various techniques, such as extrusion, molding, or pressing. The choice of forming method can influence the final properties of the bricks.
The formed bricks contain moisture from the mixing process. To remove this moisture, the bricks are dried in a controlled environment. Slow and careful drying helps prevent cracks and deformities in the bricks.
