Ternium Siderar San Nicolás
operatingBF–BOF Integrated route · San Nicolás de los Arroyos, Central & South America, Argentina
Ternium Siderar San Nicolás makes steel by the integrated route: iron ore is smelted into liquid hot metal in a blast furnace, then refined into crude steel in a basic oxygen furnace. The liquid steel is solidified into semi-finished shapes by continuous casting. The plant has a crude steel capacity of about 3.5 million tonnes per year. Its main products are tinplate, slab, cold rolled, hot rolled.
