STEEL IS ONE of the world's most innovative and essential materials. As demand has grown, so has the need for innovative techniques
and technologies to boost output and increase safety, efficiency, and
reliability within the steel industry.
According to data from the World Steel Association, Brussels
(worldsteel.org), NUCOR Steel, Charlotte, NC (nucor.com), produces more than 27 million tons of steel each year. The corporation has
become North America's largest recycler and the world's most sustainable steelmaker, offering a full range of steel and steel products.
Through customer-driven development, NUCOR and ABB,
Cary, NC (abb.com), have modernized power distribution for the

steel industry, enabling NUCOR to improve efficiency and reliability,
and, in turn, increase production output.

BACKGROUND
Steel is produced through two primary methods: the blast-furnacebasic-oxygen-furnace method and the electric-arc-furnace (EAF)
method. Historically, the steel industry has used the blast-furnace
method with coal-fired plants to process iron ore. This method is
costly, inefficient, and generates significant pollution. As more producers have turned to recycled-steel metals, arc-furnace technology
has become more prevalent, with the promise of lower costs, longer
