Ltd. were analyzed. Considering steelmaking processconditions, the optimum power-input diagrams were investigated, which can save energy, lowerconsumption, and raise productivity. This has been verified by production contrast tests.Application of the optimum curve in 50 t UHP-EAF indicates that research method is correct, the 50 tUHP-EAF runs smoothly with lowering electrical energy by 29.35 kW-h/t and shortening power on timeby 3 min. The general steps of making optimum power-input specification is also given.展开更多
