Annotation:

A modified method of calculating the characteristics of physical and chemical processes of lining material used in blast furnaces is developed. Calculations of high-temperature deformation under load and evaluation of the creep of oxide refractories are made. It is shown that the method of calculation at the first blast furnace blowing depends on the deformation mechanism, which appears at high temperature and voltage, as well as the total porosity, shape and size of pores, grain composition ignoring of which leads to significant measurement error of temperature refractory furnace.
