At Vanderbijlpark and Newcastle, liquid iron and scrap are transformed into steel in basic oxygen furnaces (BOFs). Steel is then cast into slabs (at Vanderbijlpark) for flat rolling and into blooms for long rolling (at Newcastle).
From the caster, steel slabs are cut into semi-finished products: blooms, slabs, and billets. These are either reheated (hot rolling) or cold rolled for very precise applications. Before we ship products to clients, we treat what will become our final products in many ways; these treatments include painting, annealing, galvanising, and cutting and batching to specification.
Utilising scrap steel as 60% of its feedstock, the Vaal Melt Shop in Vereeniging, with an annual capacity of 400 000 tonnes, is an electric arc furnace which has given our operations additional flexibility. In 2022, the Vaal Melt Shop produced steel inputs for our Gauteng long steel operations and for Newcastle until October when it was put under care and maintenance. In 2022, we announced our acquisition of the ArcelorMittal Rail and Structural (AMRAS) mill, the only producer of mainline rail in sub-Saharan Africa, a facility we had operated under contract since 2017.
Tubular Products is the sole producer of hot rolled and cold drawn seamless tube products in South Africa. Of 60 796 tonnes produced in 2022, 59% was exported.
