This paper discusses scientific research in the direction of energy saving and the efficiency of heat transfer processes. In this direction, in particular, in the optimization of the design and modernization of heat exchange processes, as well as in the development of energy and resource-saving technologies, it is necessary to reconsider the lining thickness of induction melting furnaces.
The research on the optimization the thickness of the lining, consists of thermodynamic and thermal processes taking place in the liquid metal bath and on the boundaries of the refractory layer of the lining. The power of heat loss through the lining of a cylindrical wall is complex heat transfer under boundary conditions of the first and third kind. Beside that the active power lost in the inductor, the power released in the metal and useful power are calculated. This has resulted in an adjustment to the overall efficiency calculation, which includes thermal efficiency and electrical efficiency.
On the basis of thermal and electrical calculations for ICF-6 LMZ with a capacity of 6 tons, the rational thickness of the lining of the crucible wall is equal to δφ = 0.115 … 0.120 mm, which corresponds to the relation Dvt/Dm = 1.23 … 1.26.
