Investigation of the Dependence of Refractory Thermal Conductivity on Impregnation with a Corrosive Medium

Features of impregnation a corrosive medium for the working layer of the lining of rotary kilns and casting ladles for ferroalloy production are considered, and results are provided for analysis of the impregnation thickness. The change in the thermal conductivity of refractories after service is investigated on the basis of a developed and patented method. It is found that the thermal conductivity of the refractory material of an industrial furnace lining working layer increases (by 5 – 12%) due to refractory impregnation by a corrosive medium.
