This study examines the temperature-dependent compressive strength of refractory lining materials used in ferrosilicon casting ladles, with a focus on ShKU-grade chamotte bricks. The thermographic analysis of the ladle outer surface, along with the inspection of the inner lining, revealed that crack formation is primarily driven by thermal stress resulting from significant temperature gradients during non-steady-state thermal processes. The visual inspection of refractory samples confirmed the role of thermal stress in lining degradation. Compressive strength was measured for the fresh and spent refractories across a range of temperatures. Results show that strength increased within a specific temperature interval, reaching values 44% higher for the fresh chamotte refractories and 56% higher for partially spent samples compared to the baseline strength at 20°C.
