Conclusions
The conditions for the formation of a slag layer in an unlined and uncooled steel pipe were determined by methods of mathematical experiment design and on hot models.
Within the investigated limits of variation of the factors the growth of the layer is governed by the degree of excess heating of the slag and its stay time in the pipe. The results of calculations of the thickness of the layer from the mathematical model constructed for this purpose agree very closely with the results of the industrial-scale experiment.
An analysis of the mineral composition and melting point of four slags of the system CaO-Al2O3 showed that among the compositions investigated the slag lining approaching the composition of CaO-Al2O3 possesses the best combination of properties.
