Iron ore pellet properties under simulated blast furnace . - JultikaJun 9, 2017 . Abstract. A blast furnace is the dominant process for making iron in the world. Iron ore pellets are commonly used as iron burden materials in a blast furnace, in which iron oxides are reduced to metallic molten iron. While descending, the charge faces various stresses, which affect the gas flows in the shaft.iron ore for blast furnace,BBC - GCSE Bitesize: Making ironIron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions. Carbon is more reactive than iron, so it can push out or.

Creating Iron | HowStuffWorks

The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and line (CaCO3). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the line combines with the silicates to form slag. Liquid iron.

Iron Ore and Pellets - Vale

But, before this, the ore goes through a blast furnace that only works when air can circulate freely. For this reason, the material needs to be big enough so that there are spaces between each piece. On top of this, the ore needs to be strong enough not to be crushed thereby obstructing the blast furnace. Thus, the production.

What constitutes lump iron ore? What is sintered iron ore and what .

In traditional blast furnace iron making, the iron ore is fed to the blast furnace in one of three common forms: Lump, pellets or sinter. All of which are designed (in conjunction with coke) to maintain a porous feed bed in the blast furnace and thus facilitate rapid and uniform reduction of the iron ore (iron oxide) to iron metal.
