When starting up a cold kiln, it is important to allow time for the tire rings to expand in pace with the kiln shell’s expansion. If heat-up is too rapid, the colder tire rings can cause shell deformation, thus crushing refractories. When the tire rings later expand to full operating dimensions, this can cause 'rolling ovality' in the kiln …
