As part of a second expansion to their facility, a North American steel company plans to install a second electric arc furnace with the assistance of a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry.

North American steel producer Big River Steel (BRS) recently commissioned SMS Group with the expansion of its steel plant in Osceola, Arkansas. SMS Group will supply BRS with additional mechanical equipment, electrical and automation systems, and digitalization, which the group reports will increase the plant’s annual output.

“I have purchased several technologically advanced steel production facilities from SMS over the past twenty years and I am fully confident that SMS group will again deliver a high-quality mill that sets the standard in terms of product capability, energy efficiency and environmental sustainability,” commented David Stickler, CEO of Big River Steel.

Following this second expansion of their facility, the steel plant will house two electric arc furnaces and two twin-ladle furnaces. In addition, Big River Steel commissioned Systems Spray Cooled for the installation of furnace cooling equipment at Big River’s Osceola facility, including furnace sidewall, roof, elbow, and off-gas duct work. SMS reports that installing an additional gas cleaning system will ensure compliance with environmental legislation. A second strand, a second tunnel furnace, and a further downcoiler will also be added to the Big River Steel’s CSP^® plant, which reportedly produces coils up to 1,930 millimeters wide.

Big River Steel produces high-quality steels, including tube grade sheet for pipeline construction, silicon steels for a wide variety of energy and electric motor applications, and advanced high-strength steels for the U.S. automotive industry.

The hot coils produced in the CSP^® plant are processed into high-grade cold strip in the downstream coupled pickling line/tandem cold mill. The continuous galvanizing line (CGL) will receive an additional coiler. For all the newly installed plants, SMS group is going to supply the mechanical equipment and the X-Pact^® electrical and automation systems, including level 3.

Also in the second construction stage, the PQA^® (Product Quality Analyzer) system developed by SMS group company MET/Con will be a central module of the process automation system. By capturing and evaluating all relevant production data on a continuous basis, PQA^® monitors, documents and assures the product quality down to the finished cold strip along the complete production process. The system uses stored rules defined on the basis of expert knowledge to assess the coil quality in a semi-automatic procedure and, based on these assessments, takes “ship” or “block” decisions for the downstream processing of the strip or its dispatch.

This system then sends instructions for action to the operators while production continues in order to make them aware of any onset of irregularities within the production process and suggest countermeasures to be taken. This allows the operators to predictively intervene in the process before an incident becomes a problem, reducing the occurrence of failures along the production process which otherwise might have resulted in poor quality and downtimes. Over time, the system is intended to provide higher yield while increasing product quality.

“Working closely with the management and staff of Big River Steel, we have succeeded in digitalizing a highly complex steel plant in a way that meets the targets of stable and resource-saving production,” said Burkhard Dahmen, Chairman of the Managing Board of SMS group. “We are very pleased about Big River Steel’s decision to also award us the order for the next expansion stage of the steel plant and to continue on the proven successful way with SMS group as their partner.”
