- Abstract: Explosive spalling is a major concern when drying refractory concretes. For safety, empirically defined overestimated slow heat-up curves are used in industry. Polypropylene fibres reduce spalling; however, they are inconvenient for certain castables due to properties deterioration, such as slag penetration. There is neither a generally accepted methodology to define monolithic refractories dry-out schedules nor agreement about a mathematical model to predict spalling phenomena. This article discusses the results of original numerical and experimental investigations when drying a castable using slow heating to 300 °C considering the influence of the methods used to characterize properties. Modifications in experimental methods allowed to reproduce real refractory lining boundary conditions and measure pore pressures. A conservative fully implicit finite volume method in three-dimensions was developed to predict pressure and moisture migration in qualitative accordance with reality. The combined methods allowed to identify unproductive heating time, enabling the reduction of energy waste.
