What is the minimum curing time for newly applied refractory lining before moving or stripping forms?

The minimum curing time for newly applied refractory lining before moving or stripping forms is 24 hours. This duration is essential to ensure that the refractory material has properly set and begun to harden, allowing it to achieve the strength and integrity required for its intended use. Curing is a critical process that affects the performance of the refractory lining, as it ensures that the material can withstand thermal cycling, mechanical stresses, and exposure to aggressive environments typical in industrial applications.

After 24 hours, the material has generally reached a point where it can handle minimal disturbance, but it still requires careful handling to prevent any damage that could compromise its function. If forms are stripped too early, before sufficient curing has occurred, the lining may be prone to cracking or other failures, which can lead to premature replacement or repair and increased costs. Thus, the 24-hour period is established based on industry best practices and guidelines to optimize performance and durability.
