Thermomechanical and Thermophysical Properties of Skull and Spent Lining of the Blast Furnace

Abstract

The paper presents the results of a comprehensive study of the thermophysical properties of 21 samples of skull and refractory lining collected after blowing out blast furnace No. 6 (EVRAZ NTMK). The open porosity, apparent density, melting point, thermal coefficient of linear expansion (TCLE), thermal diffusivity, and heat capacity of the samples are determined, and their thermal conductivity is calculated. The coefficients of the standard approximation equations of thermal diffusivity, heat capacity, and thermal conductivity for each type of skull and regenerated refractory are determined. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
