Design of the Blast Furnace Wall Structure Made of Efficient Materials. Part 1. Statement of a Problem and Calculation Prerequisites

Typical multilayered wallings of the blast furnace are considered. The description of layers which are a part of these structures is presented. The main attention is paid to the lining layer. The process of iron smelting and temperature conditions in characteristic layers of the internal environment of the blast furnace are briefly described. On the basis of the A.V. Lykov’s theory, the initial equations describing the interconnected heat and mass transfers in the solid body in relation to the set task – an adequate description of processes with the purpose of further design of the multilayer walling of the blast furnace – have been analyzed. A priory, from a mathematical point of view, the enclosing structure is considered as an unlimited plate.
