Abstract: A cracks growth in metallurgical installations refractory linings under thermal shock was investigated with mathematical modeling methods. As an example a standard periclasse – chromite refractory lining of DH-degasser was taken. Two types of thermal shock were considered – during heating and cooling of the lining. Thermal stress while preheating process was also calculated. A dynamic heat field was an initial data for thermal stress calculating. A finite elements method was choused for all calculations. The size of lining damages was calculated with method of «heat displacement». The moments of crack appearance were determinate with 3-dimentional stress field modeling. The calculating results are in good correspondence with real damage sizes, measured after finish of installation usage.
