The use of DRI as blast furnace feed enables reduction in coal consumption in blast furnaces. (When 100 kg of DRI is used for the production of 1 ton of molten iron, the consumption of coal in blast furnaces will be reduced by 50 - 60 kg.)
Iron - Essential Chemical Industry
Iron is the second most abundant metal in the Earth''s crust (after aluminium) and more iron is made than all the other metals put together. The ores, which are mainly the oxides, are reduced to iron with carbon (coke) at high temperatures in a blast furnace. Over 98
The extraction of Iron and its impact on the environment
At the base of the furnace, slag floats on top of the molten iron. It is then cooled and used for making roads. The following figure depicts the inside of a blast furnace, and how iron is extracted from haematite [Figure 5].

1. Iron ore, coke, and limestone are carried up to the top of the furnace often with skip cars. 2. The blast furnace may be more than 250 feet tall. The inside is about 30 feet wide. The outside of the furnace is a steel shell and inside of the furnace is lines with a
Iron | Geoscience Australia
Iron is about eight times heavier than water (its relative density is 7.87). When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds.
IRON AND STEEL - chemguide
2020/8/18· Extracting iron from iron ore using a Blast Furnace Introduction The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air.
How the Blast Furnace Works Essay - 1237 Words
Usage of Blast Furnace What is a Blast Furnace?A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron. In a blast furnace, fuel, ore, and flux (limestone) are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical
Characteristics and appliions of iron and steel slag : …
Air-cooled blast furnace slag This slag hardens when it reacts with water, with a hydraulic property that provides increasing strength over time. Because of its large load-bearing capacity, it is used in road base course material in the same way as gravel. There is no
Influence of Coating Granulation Process on Iron Ore …
Among these raw materials the usage of sinter in blast furnace is at higher side compared to other iron bearing materials. As the quality of sinter product improves, its usage in blast furnaces also increases. Iron ore fines are the main source for sinter making.
Blast Furnace operation: HOW A BLAST FURNACE WORKS
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2 O 3) or Magnetite (Fe 3 O 4) and the iron content ranges from 50% to 70%.) and the iron content ranges from 50% to 70%.
