Mini Blast Furnace and Iron making – IspatGuru

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...

Blast furnace | metallurgy |

Blast furnaces are used continuously and are only shut down when their brick 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.

Pig iron - blast furnace route | International Iron ...

Norway not only has an adequate limestone reserve and ample water power, but is well-supplied with raw materials for making iron and steel. Charcoal blast-furnaces were used for many years to reduce the iron ore, but since 1910 the metallurgists have persevered with the electric furnace…

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.

Creating Iron | HowStuffWorks

This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the …

Oct 10, 2016· Mini Blast Furnace and Iron making. Mini blast furnaces (MBF) are generally viewed as miniature versions of the conventional large blast furnaces (BF). These furnaces are ideally suited for small scale operations.

Use of Iron Ore Pellets in Blast Furnace Burden – IspatGuru

Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.

Pig Iron Manufacturing Process

These recipes can be performed both in Bricked Blast Furnace and Bronze Plated Blast Furnace, and the only value which varies between the recipes is the processing time. Steam Age Processing . At steam age the player is able to build these Ore Processing machines: Steam Furnace is more fuel-efficient than Furnace.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

Iron Ore - an overview | ScienceDirect Topics

Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.

Oct 10, 2017· Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.

Iron ore pelletizing systems -

Process Charging the blast furnace 1 After processing, the ore is blended with other ore and goes to the blast furnace. A blast furnace is a tower-shaped structure, made of steel, and lined with refractory, or heat-resistant bricks. The mixture of raw material, or charge, enters at the top of the blast furnace.

Iron and Steelmaking -

Iron ore is used directly in the steelmaking process in the blast furnace in the form of lump, pellet, and fines (see Fig. 5). (Fines are converted to sinter feed in a sinter plant.) Iron ore pellets are also used in the production of DRI and HBI.


­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 limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

Iron Ore Smelting Process - Brighthub Engineering

A blast furnace charge consists of ore, fluxes and fuel. The ore part of a charge consists of iron ores and concentrates, manganese ores and various types of scrap containing iron.

Blast furnaces are also called high ovens. A blast furnace is usually built with a steel case and bricks made of magnesia inside the case. Magnesia is very resistant to heat. It does not melt. The furnace is cooled with water running inside part of the case and bricks. The process of making iron is simple. Iron ore is basically iron oxide.
