There are FOUR (4) raw materials used in the Blast Furnace. They are ;-
Iron Ore (iron Oxide ' Fe2O3
Coke (Impure Carbon (C).
Limestone ( impure Calcium Carbonate CaCO3).
These three are intimately mixed to produce a 'honeycomb' of the mixture named ' Sinter'.. Because of this 'homeycomb' it allows the hot air to enter and intimately mix with the sinter and react.
AND Don't FORGET OXYGEN ( The hot blast of air).

Why is a blast furnace called blast furnace?
how does the blast furnace maintain the heat ?what is the function of CaCO3 ?how the slag protect the molten iron ?why does iron flow down to the bottom /how does the slag and molten iron get seperated ?what is use of waste gas /what is main impurity of iron in blast furnace ?
Why does iron from a blast furnace have only a few uses?
Iron from a blast furnace is typically impure and contains high levels of carbon, making it brittle. This limits its use in applications requiring high strength or ductility. However, it can still be used in construction and manufacturing processes where its strength and durability are not critical.
Why is aluminium extracted using the blast furnace and not electrolysis?
Aluminium is extracted using electrolysis because it has a high melting point, making it more energy efficient to use electrolysis rather than the blast furnace. The electrolysis process involves passing an electric current through a molten aluminum oxide mixture, which separates the aluminum from the oxygen.
How do you use raw material in a sentence?
Many African countries have a large amount of raw materials ,but they haven't developed very well
How is slag removed from the furnace?
Gas BlowersGas blowers use blasts of a gaseous material to remove slag from furnace walls. These tools work in a way that is similar to other blowing tools, like snow blowers or leaf blowers, but use strong, concentrated bursts of gas. Blowers for slag removal, which include jetblowers and sootblowers, often use heated air. This weakens the connection between the slag and furnace wall and leads to quick removal. Gas blowers usually use air or steam. Steam, given its high temperatures and moisture content, attacks slag in a different and more aggressive way than dry air. Sootblowers exist primarily to remove soot from furnaces, though many factories with coal furnaces use them as slag-removal tools in tandem with other tools such as water cleaners and chemical treatments.

What has the author Tunner written?
Tunner. has written: 'On the use of lignite or brown coal in the blast furnace' -- subject(s): Blast furnaces, Lignite
What is use of mud carbon in blast furnace?
Mudgun is hydraulically operated machine that is used to close the tap hole of the blast furnace after draining out the metal / slag from the furnace from time to time. It is heavy equipment and the most critical of all the equipments used in blast furnace. The failure of the machine will lead to shut down of the furnace to close the tap hole.
Can the slag on a blast furnace be used in concrete or cement?
Slag from a blast furnace is usually ground down and used as a cement substitute as it is re-use of a waste product - it is not used on its own in concrete as the chemical reaction will not produce the same strength as proper cement.
How nut coke is charged in blast furnace?
According to steel.nic.in; Coke Rate is measured in Kgs of BF Coke consumed per tonne of Hot Metal produced in the Blast Furnace(Kg/THM). By convention, this excludes coke (nut/pearl coke) mixed with sinter etc. Introduction of high quality coke to a blast furnace will result in lower coke rate, higher productivity and lower hot metal cost. This principal is followed by many private chemical firms like Coke Oven Consultants and so on.
Where is the use sponge iron?
Sponge iron is used as a raw material in the production of steel through the electric arc furnace or basic oxygen furnace routes. It is typically used as a substitute for traditional iron ore in steelmaking processes due to its higher iron content and lower impurities.
What raw material does a cow use?
Plant matter.
How did the use of raw material change after the war?
Raw materials were used by new southern industries.
Where does the raw material for aspirin come from?
The raw material for aspirin comes from the bark of the white willow tree. The medicinal use was first discovered in 1763.
How did the south's use raw material change after the war?
Raw materials were used by new southern Industries

What are the pros and cons of using a blast furnace?
Blast furnaces are efficient for producing iron and steel, allowing for high-volume production and the use of various raw materials. They can also be integrated with other processes, enhancing overall productivity. However, they are energy-intensive and contribute significantly to carbon emissions, raising environmental concerns. Additionally, the initial capital investment and maintenance costs can be substantial.
