Resumo
FINEX® is a new ironmaking process that is based on the direct use of fine ore and non-coking coal. The key technologies involved are the fluidized-bed reduction of fine iron ore, the hot fine DRI(direct-reduced iron) compaction to HCI(hot-compacted iron), the briquetting of fine coal, and the melting of HCI into hot metal. A 1.5 mtpy FINEX® commercial plant has been operating at Posco’s Pohang Works since April 2007. The start-up operation was carried out smoothly, and improved gradually over time. Recently, the normal operational performance has been achieved, satisfying target values of production rate, coal consumption, plant availability, and hot-metal quality.
