Brazil: ArcelorMittal has ordered a slag retention system from UK-based Primematals Technologies. This is part of a larger order for two 135t LD converters for basic oxygen furnaces (BOF) at its steel plant in Jõao Monlevade. The Vaicon Stopper slag retention system is intended to minimise the amount of slag that enters the ladle during tapping. This system ensures shorter production cycles and higher steel quality compared with conventional slag retention systems. The overall plant project also includes an upgrade of the primary dedusting systems and complete electrics and automation packages. The start-up of the new equipment is scheduled for the first quarter of 2025.
The Monlevade plant produces wire rod for industrial applications such as steel wool and steel cord. The site is part of ArcelorMittal Brazil’s Long Steel division and has an annual capacity of 1.2Mt/yr.
