AI Technical Summary

Technical Problem

Existing refractory drying processes rely on temperature gradients as the core driving force, resulting in high energy consumption, long drying cycles, and a tendency for structural defects in the blanks, making it difficult to meet the energy-saving and cost-reduction needs of the refractory industry.

Method used

Using the water vapor partial pressure difference as the core dehydration driving force, combined with the reverse linkage adjustment of the chamber temperature and the absolute humidity of the environment throughout the drying process, the drying process is controlled in stages. Through five continuous stages, the moisture migration law of the blank is precisely matched, and a segmented gradient low temperature drying method and control system are used.

Benefits of technology

Achieving efficient dehydration of refractory materials in low-temperature environments significantly reduces drying energy consumption, avoids damage to the green body structure, improves drying efficiency and quality stability, and enables automated closed-loop control.
