What is the drying method for hot wall refractory line components?

The drying method for hot wall refractory line components involves simultaneous heating from both sides. This approach ensures that heat is uniformly distributed throughout the refractory material, which helps eliminate moisture more effectively and reduces the risk of cracking or thermal stress during the drying process.

Simultaneous heating is particularly advantageous because it allows for a more controlled and even warming of the refractory, facilitating the removal of moisture from both the interior and exterior surfaces at the same time. This method enhances the integrity of the refractory material and prepares it for subsequent use in high-temperature applications.

Using only outside surface heating might lead to uneven moisture evaporation, potentially causing thermal gradients that could cause damage. Limited heating from within could also result in similar issues with moisture retention. Steam curing, while effective for some applications, does not provide the necessary drying effect for hot wall components, which require a dry environment before being put into service.
