Bosnian steel producer ArcelorMittal Zenica started up a new 125 tonne LD converter, supplied by Primetals Technologies, at its plant in Zenica in Bosnia Herzegovina in Autumn of 2022. As part of the project, engineers at Primetals Technologies have optimized the vessel shape, resulting in an increase in converter reaction volume by almost 30%. The new technology has also reduced the tap-to-tap time, which has led to a higher capacity for the production line. At the same time, ArcelorMittal Zenica is now able to produce a wider array of steel grades.A converter vessel, a trunnion ring, and Vaicon Link 2.0, the maintenance-free suspension system, were the key equipment included in Primetals Technologies’ scope of supply. Primetals Technologies was responsible for engineering, project management, and quality assurance, and provided advisory services for construction work and implementation together with its consortium partner.The new converter technology implemented at ArcelorMittal’s plant in Zenica has resulted in further benefits for the steel producer. Slopping, i.e. slag flowing over the converter, was a common issue with the old equipment. Thanks to the optimized shape of the new vessel, this problem sno longer exists. Therefore, a higher percentage of the yield is generated, which also contributes to greater productivity.The ArcelorMittal Zenica plant, founded in 1892 and operated by ArcelorMittal since 2004, is located in the center of Bosnia and Herzegovina. 2,300 employees make it the largest producer of long steel products in the Balkans, with an annual production capacity of almost one million tons. The product range includes rebar, wire rod, mesh, and lattice girders.
