Abstract

As an iron source of blast furnace which can adapt to recent high production rate operation and CO₂ problem, reduced iron may attract attention in the near future. In this study, reduced iron melting test was performed using an experimental blast furnace with use of HBI (Hot Briquette Iron) which is one of the reduced irons in order to quantify effect of increase in production and reduction effect of reducing agent rate for blast furnace.
