Customer challenges
in the metallurgical industry

Steel and aluminum melting are both vastly energy-intensive processes carried out with loads that have high power demand and that are disturbing the power grid, mostly Electric Arc Furnaces (EAFs). Electric Arc and other types of furnaces frequently cause power quality problems, including voltage variations, flicker, poor power factor, and harmonic distortions.

Poor power quality means longer melt time, lower productivity, energy losses, and higher operating costs. If steel plants or rolling mills are connected to weak power grids and fail to operate at full power, production capacity is affected. Moreover, if connected to the public grid, their operation may disturb any customers connected to the same grid, and thus the grid operator may curtail the plant’s operation. This has direct impact on productivity and causes significant revenue losses.

Applications like AC and DC Electric Arc Furnaces (EAF), Induction Furnaces (IF), Ladle Furnaces (LF), shredders, hot and cold rolling mills, etc.
