What is difference between Cupola furnace and blast furnace?
In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres. A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron. A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks
What is made in a blast furnace?
Several things come out of blast furnaces. They are listed here: 1) A molten version of whatever material was put in it to begin with, 2) Incredible heat, 3) Powerfull light, 4) A waste gas and usually some slag remnant of the fuel that powers the furnace.
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.
What is the name of the furnace that first made possible the smelting of iron in a molten state?
I think its a blast furnace
What is the waste gas in the Blast Furnace used for?
It is mostly carbon monoxide and nitrogen gases which has some heating value. So it is typically recovered and mixed with natural gas, &/or coke oven gas and used in boilers for steam or other steel heating furnaces for further processing of steel.
Which three substances are put into the blast furnace?
Limestone, Iron Ore and Coke.
Pig iron is produced by heating the coke iron and limestone in a what?
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.
What are the three substances fed into the blast furnace?
Carbon rich coke limestone and iron
What goes into a blast furnace?
Sinter, which is a mixture of iron ore, coke and limestone, and a blast of hot air. Externally to the furnace, iron ore, coke and limestone are mixed together Intimate mixing ensures that the reactants are as close as possible to each other. This is loaded into the top of the blast furnace. A blast of hot air ( ~ 1100 oC) is sent in at the bottom of the furnace, through tuyeres. The oxygen (air) is also one of the reactants. The products are tapped from the bottom of the furb=nace are liquid iron and 'slag' ( calcium silicate).
What raw material are put into a blast furnace?
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 raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
What is coke for in a blast furnace?
the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.
What is the process of iron smelting?
Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron. The limestone neutralizes acidic sulfur compounds and acts as a flux.

Why is Limestone added to a Blast Furnace for producing Iron?
it purifies it
How is iron refined?
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
What must be done to iron ore to produce the element iron?
Iron goes through a number of stages between ore and final steel product. In the first stage, iron ore is heated with limestone and coke (pure carbon) in a blast furnace. A blast furnace is a very large oven in which the temperature may reach 1,500°C (2,700°F). In the blast furnace, coke removes oxygen from iron ore Read more: http://www.chemistryexplained.com/elements/C-K/Iron.html#ixzz1820JDBkZ
