Heat Transfer in the Enelosing Structures of a Blast Furnace. Part 1. Statement of the Problem and the Prerequisites for Calculation

Multilayer shielding structures of the blast furnace were examined. A description of the layers that are a part of these structures is presented. The lining layer is focused on. The process of cast iron smelting and the temperature zones of the individual layers of the blast furnace internal environment are briefly described. Based on A.V.Lykov's theory original equations were analyzed, they describe interconnected heat and mass transfer in a solid object as applied to the given problem – appropriate process depiction aimed at the further rational development work on the multilayer shielding structures of the blast furnace. A priori the shielding mathematically is considered as an unlimited plate. (paper)
