The Strength and Density of Green and Reduced

Composite briquettes or pellets consisting of iron ore, carbon, and a binder are a source of direct reduced iron DRI. In the handling of green and reduced briquettes, high strength is important to minimize briquette breakdown. The use of charcoal as a source of carbon, rather than coal provides a way of introducing renewable carbon into the ironmaking process.

Introduction to Iron ore Pellets and Pelletizing

Induration During the induration, heat hardening of green pellets is carried out. Induration of green pellets consists of three main steps namely i drying of green pellets, ii firing of pellets at around 1300 deg C to sinter the iron oxide particles, and iii cooling of hot pellets before discharging.
