Abstract In order to predict reasonable electrode immersing depth in different electroslag remelting processes， the corresponding slag pool resistance values for different electrode-immersing depths， slag amounts and slag conductivities under steady-state conditions in the industrial electro-slag remelting process were obtained based on the MHD model in Fluent software. Then combined with the actual factory production regulations， an electrode-immersing depth mathematical model was deduced from the relationship of the voltage， the current， the slag weight and the slag conductivity. The results of the comparison between the calculated values and the measured values showed that the relative error of them was very small. The cleanliness of the steel was obviously improved and the problem of the oxidized Al elements and the excessive increase of oxygen was effectively solved by adjusting the slag system and increasing the slag amount in actual production situations based on the aforementioned model.
