Abstract
For the operational guide of electric furnace for producing silicomanganese, a new simplified mathematical model suitable for online application has been developed on the following procedure.
(1) Equations for the estimation of reaction rates are derived from material balance through the charge conditions and the exhaust gas compositions.
(2) The ratio of transference of MnO, FeO, SiO2 into slag and the amount of permeation of carbon into metal are formulated as the functions of operational variables.
(3) By using the above-stated formulated equations, the transition of metal formation rate and metal temperature can be estimated.
At EF shop No. 2 in Kashima Works of Chuo Denki Kogyo Co., Ltd., the model is being used for the guidance of the operation and contributes to the reduction of electric power consumption.
