Since early 2015, the continuous caster of Slovenian steelmaker Acroni (member of SIJ – Slovenian Steel Group) that was modernised by Primetals Technologies produces X120Mn12 wear-resistant grade. This is due to the optimised interplay of the technology packages, machine head and strand guide system supplied by Primetals Technologies, which ensure the required high internal and surface quality of slabs.
Acroni is the leading European producer of quarto stainless plates, also specialised in electric and special steels, sold in the form of hot and cold rolled coils, steel plates and cold formed profiles, mainly for special niche products. The single-strand continuous caster was radically modernised by Primetals Technologies. The machine head and strand guide system were replaced and new technology packages, systems and components installed. It is designed for casting around 515,000t of steel annually, including medium to highly carbon and peritectic steels, structural steels, microalloyed and stainless steels as well as silicon steels. The slabs have thicknesses of 200mm or 250mm and widths of 800mm to 2,120mm.
Wear resistant steels such as X120 Mn 12 grades can now also be reliably produced on the bow-type continuous caster. Previously this grade was produced as ingot or on vertical continuous casting machines. This is made possible by the optimised interplay of machine head, strand guide and technology packages.
