Overview

Merchant products are manufactured from steel scrap, melted in an Electric Arc Furnace followed by hot rolling. Electric arc furnace steelmaking and rolling occurs at the Charlotte, NC facility, and the Charlotte steel mill also produces carbon steel rebar. Gerdau awarded Russula a contract to upgrade the 350,000 tpy bar mill in Charlotte.

Profile

Electricity and grid: The EAF is fed from a double 100 kV sub-transmission circuit. The EAF, rated at 30/33 MVA, as well as a ladle furnace rated at 18 MVA are taking their power from a 100 kV supply grid. A Hitachi Energy SVC Light rated at 13.2 kV, 0-64 Mvar (capacitive) was commissioned at the end of 2006, because the power utility set up more strict requirements on mitigation of flicker.

Ownership: The EPA registry lists Gerdau Ameristeel US, Inc. as operator and owner of the facility. The EPA greenhouse gas report lists GERDAU USA INC as parent company with 100 percent ownership interest.

Permits: The state stormwater program acknowledged the facility’s renewal application for coverage under NPDES Permit NCS000304 and issued a draft permit, for the Charlotte Mill in Mecklenburg County.
