Rectifiers for DC electric arc furnaces

 

DC power supply for steel, ferrochrome, titanoxid, ferronickel and arc furnaces - Increasing power quality for faster return on investment (ROI)

The primary goal of any electric arc furnace operator is to minimize overall capital costs, optimize production line quality and maximize efficiency and revenue. A further requirement is smooth and gentle operation in order to boost production line quality and lower the impact on the power grid. When it comes to power quality, power utilities can be very demanding, especially in the case of weak grids in remote locations.

That is why ABB offers an integrated system of DC power supplies for arc furnaces including power quality equipment that provides an unrivalled low life cycle cost to give you technical performance that boosts productivity and allows a fast ROI (Return On Investment) on your plant.
