A New Advanced Energy Center Computer System in Steel Works

Abstract

For energy saving in integrated steel works, it is important not only to develop the technique in process (e. g., optimal control of heating furnaces and recovery of waste energy), but also to establish the following techniques for keeping energy demand/supply balances optimal.
(1) Daily production scheduling of works under the condition of balances of blast furnace gas, LD gas, electric power, steam and so on.
(2) on-line optimal controlling of demand/supply of energy while it varies time to time.
In Wakayama Works of Sumitomo Metal Industries, a new energy center compurer system has been developed to put these facilities in practice, and the expected energy saving has been achieved.
