Thermal Stability Testing of Refractory Specimen
The most important properties usually measured for refractories are working temperature and thermal stability. Thermal stability of the alumina based samples was measured using standard laboratory procedure, water quench test (JUS.B.D.8.319). The ImagePro Plus program was used for image analysis of deterioration monitoring of the samples before, during, and after water quench test. Mechanical characteristics were considered such as strength, dynamic modulus of elasticity resulting from resonance frequency measurements, as well as ultrasonic velocity. In this work correlation between deterioration, ultrasonic vtelosity, and strength on thermal stability of the samples were investigated. The results were used for validation of the model for the thermal stability behavior prediction of the refractory.
