東和鋼鐵苗栗廠直流電弧爐電極棒電極控制系統的改善

東和苗栗廠使用法國CLECIM 110噸直流電弧爐及日本Toshiba發展的電極昇降控制系統。因受廢鋼的影響，電弧爐工作環境雜訊很大，容易產生高的電壓及電流變動，增加單位熔煉成本，且降低設備壽命和減少產能。東和研發部經由分析及模擬技巧，解決電極昇降控制系統的穩定性，因而提昇電弧爐的熔煉效益，使Flicker值降至0.27及熔煉單位耗電量節省4.37％、又經現場同仁的其他改善措施，電極棒耗用由1.9 kg/ton降至低於1.1 kg/ton。

At Tung-He Co's Miao Li Works, a CLECIM 110-ton DC EAF has been installed. It is equipped with an electrode control system developed by Toshiba. Owing to the interference of charged scraps, the EAF has been worked instinctively at a very high noise environment, easily producing fluctuations in voltage and current, thus increasing the melt down cost. In addition, these factors also decrease the capacity and life of equipment. However, the in-stability problem of the DE EAF electrode control system was solved by using analysis and simulation techniques, thus the EAF efficiency was improved. This effort caused the flicker to reduce to 0.27 and a saving of 4.37% in power consumption was obtained. Further more, by aid of other improvements, a decrease in electrode consumption from 1.9 kg/ton to below 1.1 kg /ton was observed.
