With the second oil crisis as a turning point, energy issues have come to occupy a most vital position in business. For the steel industry in particular, which is a heavy oil consumer, energy conservation is as vital as it is anywhere. Steelmakers are therefore committed to a variety of energy-conserving measures, including (1) the installation of waste heat recovery facilities, (2) the organization of elaborate economizing campaigns, (3) the orientation toward continuous operations (continuous casting, etc.) by integrating indispensable processes and excluding dispensable ones, and (4) the increased use of hot rolling and direct rolling, etc. On the other hand, the steel industry has energy-generating facilities and by-product energy-generating processes that form a complicated energy supply-demand structure. Energy balance is intimately related to the operating rate and the operating method of each steel works, and this so much so that the minimization of specific energy costs does not necessarily entail total cost minimization. Because of this, there is a rapidly expanding need for a scientifically built “software system” within which the aforementioned relationships are quantitatively analyzed to minimize overall plant costs in relation to the changing external environment. This paper discusses this system by referring to the developments and achievements made so far by the Yawata works of Nippon Steel Corporation. |
