In order to automate the electrode replacement process, it is necessary to estimate the electrode consumption. Because the electrode controller lowers the electrode according to the electrode consumption, it is possible to estimate the consumption by measuring the position of the electrode. However, due to the structure of the electrode and the electrode arm, it is difficult to measure the electrode...
In this study, we estimated slag foaming height from the vibration signal in an electric arc furnace (EAF). A fast Fourier transform (FFT) was used to determine the characteristics of the vibration signal in frequency spectrum. The reference height was obtained by analyzing an image of the slag gate. Finally, we developed an estimation model by using the least mean square (LMS) algorithm on the basis...
