A destruction of metallurgical installations lining under thermal shock was investigated with mathematical modeling methods. As an example a periclassechromite lining was taken. Two types of thermal shock were considered -during heating and cooling of the lining. It was determinate, that these two types of thermal shock cause a different character of damage. A dynamic heat field and thermal stress of the lining during the thermal shock were calculated with finite elements method. Also, the size

The calculating results are in good correspondence with damage sizes, measured after finish of installation usage.
