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.[1]
In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process.[2]
In contrast, air furnaces (such as reverberatory furnaces) are naturally aspirated, usually by the convection of hot gases in a chimney flue. According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead would be classified as blast furnaces. However, the term has usually been limited to those used for smelting iron ore to produce pig iron, an intermediate material used in the production of commercial iron and steel, and the shaft furnaces used in combination with sinter plants in base metals smelting
How does a blast furnace work?
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.
Are blast furnaces better?
Using a Blast Furnace is more or less the same as using a regular Furnace. Just pop some fuel in the bottom-left section, and follow it with the smeltable item in the top-left section. Remember, Blast Furnaces can only smelt things. But, while they do so at twice the speed, it uses fuel at twice the rate too

1538°C...qki me khud kam karta hun steel line me....1600 se 1700 ...tk me puri tarh liquid. ...👍🏿
Type of zone in Blast furnaces ?? please Reply
SIR Ji COREX process pe ek detailed video bana dijiye plzzz
Slag is used for making roads and alse in cement manufacturing.
Nice information
yes but now days lots of other uses are there to get profit and to do recycling they are making civil grade sands too
Sir please make a video on COREX and MIDREX process.
I done my intership in SAIL( bhilai steel plant) making pig iron from iron ore is not a eassy work
Ap jaisa teacher dekh ke fir padne man kar rahahe....bht hi acha se har bat samaj arahahe........thanks sir

Sir mai ek din iska steel plant kholunga apne dum pe ❤️
Waah all the best
Coke oven me
To fir humko manager ka post de dena ok bro
Bhai mujhe job dena
इसको लगाने का खर्चा 45 करोड़ है।
You have explained really well. Ek request hai. Agar aap ek video banaye on steel plant operation.
I can help u ... If u don't mind
You want explanations about in heat treatment? Self in process as operation line
The way of teaching is very good sr i can easily understand all process
Pig iron from c.l, steel
Is it also called blast stove
Sir bahut badhiya explanation tha maza aagya padhne me sir aap bahut mehnnat kartein hain hamare liye thank you sir😊😊😊

Sir Refractory brick ka material kya diya jata hai BF me???
And sir Why we don't use iron ore fines in blast furnace?
Iron melting point 1539
Melting point of iron 1439-1450 degree centigrade.
Sir pig iron isiliye bolte hai kyuki Jo molten iron milta hai usko pig jaise dikhne Wale sand ke moulds mein dala jata tha purane jamane mein isiliye usko pig iron bolte hai
Coke oven k Bare m video banaye
Sir modgan and drill machine ke bare me ek video banaiye na
My Idol
सर आयरन का मेल्टिंग प्वाइंट 1535°C होता है
why we are not increase preheated air temperature above 1200°C in blast furnace.
A very good question. Because temperature of the preheated air further increases due to reaction of limestone into quicklime. If the temperature of preheated air is already increased, there will be disturbance in the temperature gradient throughout the blast furnace.
Cowper Stoves' Plant , near Blast Furnace , supply Preheated Air Blast to Blast Furnace.
