What temperature range must be maintained during the curing period of refractories?

Maintaining the temperature range of 70°F to 85°F during the curing period of refractories is crucial for ensuring that the material properly hardens and develops its intended physical properties. This range provides an optimal environment for the chemical processes involved in curing, allowing for effective moisture evaporation and minimizing the risks of cracking or defects.

At temperatures below 70°F, the curing process can slow down, preventing the material from achieving proper strength and durability. Conversely, temperatures above 85°F can lead to accelerated evaporation of moisture, potentially causing issues such as uneven curing or rapid setting, which can compromise the integrity of the refractory material.

By adhering to the 70°F to 85°F temperature range, the curing process is balanced, supporting an even, controlled hardening of the refractory and ultimately leading to a successful performance in high-temperature applications.
