Iron Ore Processing for the Blast Furnace

blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").

Blast furnace - Wikipedia

Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.


HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

The Making of Iron & Steel - SEAISI

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.


Blast furnaces are used continuously and are only shut down when their stone lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.


Figure 1: Artist impression of a cross-section of a blast furnace. The transport phenomena and physical status in the hearth of an iron making blast furnace are very complicated and difficult to monitor and characterise. The non-uniform flow, heat transfer, and carbon dissolution from the refractory and the coke bed (dead man) cause large

How Pig Iron is Converted into Iron and Steel in …

Blast Furnace. After mining, various kinds of iron ores are brought to the blast furnace which is the starting process for refining iron ores or mined ores and for the production of pig iron. Blast furnace was invented in 14th century. A typical blast furnace along with its various parts is shown in Fig. 1.

Studies on Blast Furnace Slag Flow Characteristics

reaction rates and thus the blast furnace process of iron making. The blast furnace can be roughly divided into a number of zones out of which the granular zone, the cohesive zone, the bosh and the hearth are important. The cohesive zone from the point of view of gas flow and permeability of the bed is of paramount importance. This zone
