Abstract [en]

The aim of this report was to investigate new methods for measuring the condition of the scrap in the electric arc furnace. This was done by evaluating three different methods theoretically and chooses two of them for test in the electric arc furnace in Avesta. Due to lack of time and equipment only Total harmonic distortion (THD) measurements was used. The results show that THD reaches low values during refining. This suggests that all the scrap is melted and the arcs are stable.
