"A stable arc at higher voltage is the key to achieving increased production and reduced operating costs in a steel mill. This can be achieved by using ABB’s ARCARE® system. The system provides better use of installed capacity, resulting in a highly efficient way to produce more steel. Moreover, installing the system causes minimum disruption to the ongoing production. Based on Hatch SPLC (Smart Predictive Line Controller)TM technology, the ARCARE® system allows the alternating current electric arc furnace (AC EAF) to operate at higher power, with improved arc stability. This reduces tap to tap time, electrical energy consumption, electrode consumption and electrode breakages by eliminating vibrations due to the absence of current swings. Reduction in power-on time and balanced currents across all phases lowers refractory consumption. Although the technology works in series with the process, its implementation can be in parallel, while the steel mill is in operation. The ARCARE® system is the answer for needed holistic approach to achieve higher production with reduced graphite and refractory consumption, reduced maintenance cost and higher efficiency."
