Abstract
The methods of decreasing the lining corrosion rate by controlling the temperature regime are analyzed. It is shown that selection of a proper combination of refractory material layers would allow a noticeable decrease of the lining corrosion rate at interaction with liquid metal, but this also would increase heat losses due to convective and radiation heat transfer. A proper algorithm is suggested to reach the optimal solution by optimization of the lining layer thickness and composition. 9 Ref., 2 Tabl., 1 Fig.
