Why is the cast iron obtained from the blast furnace is treated further to produce steel?
It's not. PIG iron from the blast furnace is treated further to produce steel. Cast iron is a product made from only iron, like a cast iron frying pan. When they make a cast iron frying pan, it's ready to be sold and used. Pig iron is sent to steel mills and converted to steel.
What type of rock is used to make steel?
Steel is made from iron. Iron ore is reduced in the Blast Furnace , using iron ore, limestone, and coke, together with a 'hot blast' of air(oxygen). The product is motel iron and slag. Slag is used to make road surfaces and 'breeze blocks', for building. The molten iron is then placed in the BOS (Basic Oxygen furnace) plant, where an oxygen lance blows oxygen in to remove any impurities, and control the level of carbon present. The impurities present are phosphorus sulphur, carbon. The oxygen lance oxidises these substances into to gases , where they are drawn off the BOS plant. It is at this point the percentage carbon etc., is controlled, in order to make the appropriate steel. The result is steel.
What is the use of carbon dioxide?
used by plants and trees to be turned into oxygen.
Refining process that occurs in a blast furnace?
The refining process is actually a REDUCTION process. The iron ore ( oxidised iron ) is reduced in the Blast Furnace to IRON. Three substances are mixed and added to the Blast Furnace. They are Iron Ore (Iron(III) Oxide ; Fe2O3) Coke (Carbon ; C) Limestone ( Calcium carbonate ; CaCO3) A Blast of Hot Air is sent in from the bottom (O2) The heat makes the limestone decompose to calcium oxide(CaO) and carbon dioxide(CO2) The Carbon then reacts with the carbon dioxide and also the air to form carbon monoxide. CO2 + C = 2CO & "C + O2 = 2CO (4CO) It is the Carbon Monoxide (CO) that reacts with iron ore to form iron. as carbon monoxide is a powerful reducing agent. 2Fe2O3 + 4CO = 4Fe + 4CO2 (Not Balanced) As a secondary reaction the calcium oxide reacts with the impurities in the iron oxide (viz. sand ; SiO2) to form 'slag' (calcium silicate) . CaO + SiO2 = CaSiO3 (slag). Calcium silicate is used top make road surfaces, and 'breeze' blocks for building. The iron that is collected is still impure, and whilst liquid hot, is placed in a BOS plant with an oxygen lance, to oxidise any remaining impurities, viz. sulphur, (to sulphur dioxide) and phosphorus(to Phosphorus oxide). The carbon impurity ( to carbon dioxide) is controlled at this stage in order to make steel , which contains about 0.1% to 2% carbon , depending on the nature of the steel.
Is steel made of rock?
no steel is not made out of rocks its made out of iron

Is blast furnace a batch furnace?
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.
What do you mean by iron ore pellet plant?
It is the plant where the iron ore is processed to make the marble sized product called pellet which is used as a feed for blast furnace to produce steel.
Why is steel used to make the body of cars instead of iron?
Iron can rust. Actually it is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason
What is an iron production?
The production of iron or steel is a process containing two main stages, unless the desired product is cast iron. The first stage is to produce pig iron in a blast furnace. Alternatively, it may be directly reduced. The second is to make wrought iron or steel from pig iron by a further process.
Why is steel rather than pure iron used to make car bodies?
It is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason
How do you make iron in xbox 360 minecraft?
It is impossible to make iron in Minecraft, but it is possible to make iron ingots. To do this, you need a furnace, some coal, and iron ore, you put the coal in the bottom part of the furnace, and put the iron ore in the top, over time, you will get iron ingots.
How do you make an iron bar on minecraft?
you have to mine iron ore then put it in a furnace and you will get an iron bar called an iron ingot.
What can you make out of iron ore in Minecraft?
The only thing you can do with Iron Ore in Minecraft is smelt it in a furnace to get Iron Ingots.
What are the 3 raw materials used to make iron?
On RuneScape? A pickaxe, iron ore, and a furnace.
How do you meke iron bars on runescape?
you have to find iron ore in caves underground and occasionally on the surface, then get a furnace and smelt it. you will need wood or coal to power the furnace and 8 cobblestone to make the furnace
How do you get iron with iron ore minecraft?
You have to mine iron ore and coal make a furnace and melt the iron ore to make iron ingot. Update: THANK YOU SOOO MUCH!!!!!!
