摘要：

Based on the acoustic sound emission and the electrical parameters, an algorithm for foaming slag detection at a DC-EAF is presented. Regardless of the currently applied electrical power, the model provides a reliable estimate of the slag level. Empirical studies at the DC-EAF of the Georgsmarienhutte GmbH demonstrate the applicability of the signal as a slag index. Thus a robust tool is given to detect a poorly shielded arc at an early stage. In a second step the slag signal was integrated into an existing power control concept. Aim is to adjust power input dynamically to the process conditions.
