How far apart should refractory anchors be spaced in large areas?

The spacing of refractory anchors in large areas is crucial for the integrity and functionality of the refractory lining. The correct answer indicates that refractory anchors should be spaced 10-12 inches apart. This spacing is deemed optimal as it provides adequate support for the refractory material, allowing it to maintain its structural integrity while also accommodating thermal expansion and contraction that occurs during furnace operation.

When refractory anchors are spaced too close together, it can lead to unnecessary stress concentrations in the material, which might cause cracking or failure under high-temperature conditions. Conversely, if they are spaced too far apart, the refractory lining may not be adequately supported, risking sagging and displacement over time. The 10-12 inch spacing strikes a balance, ensuring that the refractory material remains securely anchored while allowing for the necessary movement due to thermal cycling.
