Fundamentals of scientific methodology of calculation of nonferrous metallurgy furnaces

Abstract

Essence of metallurgical furnace operation. Modern metallurgical furnaces are most properly regarded as complex physical and chemical units, in which a whole complex of diverse in nature processes occur. If we combine these processes into their most characteristic varieties, we can distinguish the following: technological, heat exchange, energy, movement of gases, movement of materials and products. All of them proceed in the working space in close mutual connection and mutual conditionality and often coincide in their purpose and definition. For example, the technological process of oxidation of sulfides is simultaneously and energetic, providing the necessary for the operation of the furnace heat release. The movement of molten slag in ore-thermal electric furnaces is simultaneously a process of convective heat exchange in the bath. The main of these processes, of course, is technological, so the basic parameters of metallurgical furnaces and the development of all processes in them should provide the technological process optimal flow conditions with the best qualitative and quantitative indicators.
