hi can u hep me? can you suggest a book on this subject? why efficient desulfurization and dephosphorization cannot be obtained simultaneously in either the blast furnace or the basic oxygen furnace?
That's because of the difference in the favourable conditions for dephosphorization and desulphurisation ... you can follow basic books like Ghosh and Chatterjee, Iron and Steel making book !!
There is thermodynamics n kinetics involved, still v good desulf. got in bhilai blast furnace up to a level of.01-.015, but that's not economic, why high temp., high basicity slag, optimum mgo content for good fluidity slag ; that's why external desulf. is better, . high dephos. In steel making is also possible, will discuss later.
Friend the link of drive is not opening else it has been removed I want to solve other examples regarding the b.f extraction Please look into this and share the link thanks😇
Why did you not take account of Carbon and Oxygen from CaCo3, SC choria sir (nptel) has clearly that this has be to taken into account for Carbon and Oxygen balance
Yes, I clearly mentioned that we should do it...but it will make our calculations so complex...and for GATE...we can easily get through with the major components mentioned !
@@bharatisahu9722 Yeeah please go with the nearby option in that case...because i assumed the inputs and outputs of carbon and oxygen for general calculations...for precise values you must take all the oxides and all the carbon which makes our calculation difficult !!
Please solve this problem...* Copper , milled , smelted and then refined . The Following information is avialab;le: Mill recovery Rate : 80 % , Avg Grade in Mit Concentrate : 25 % , Loss in Smelting Process:4 Kg/ I of Concentrate. Loss in refining Pracess: 2 Kg. /T of Blister Copper. Calculate the Quantity of refined Copper from per Tonne of ore. Copper ore grade is .65%.
thank you very much for this video and sharing the links...great initiative...keep it up
Thanks a lot buddy...plz share the videos with all Gate MT Aspirants !
Thank u sir for explanation on iron making .☺
Thanks for all your positive responce and support....please do share with Gate aspirants...and stay subscribed for coming steel making videos😊
I wonder how such calculations can be expedited in exam..🤔 Btw absolutely brilliant explanation, short n crsip, thank you sir🙏
Haha exams may not ask you all at once....bt if asked ..we had to do it...and thanks
There is no link for drive in description kindly check and add it. M not able to find numerical extractive metallury
Please post a video about Heat balance. It is more complicated than mass balance.

For blast furnace iron making - akbiswas is the best book in the world
Really helpful....thanx a lot brother
Thanks for the words buddy....please share with your classmates and friends...!
in 3rd question, C also be present in CaCo3 but why not included of carbon from CaCO3 in balance eqn.?????????
plz plz sir reply me
To make calculations easy....that's the reason we didn't consider oxygen coming from all oxides also...the same way, it can be neglexted
C balance n oxygen balance, should be considered
Plz post videos on PCi calculation
Sir the google drive is not working...please update it ....thank you in advance
Superb explanation
Thanks a lot, do share our videos !
very nice explanation.
I would like to know any reference books for these topics
Thanks a lot and you can follow A.Ghosh and Chatterjee for iron nd steel making
@@everythingmetallurgy hi i have some doubts in the formulation part.. Seeking ur help.. Can u provide me ur mail id or WhatsApp number
#Good work #keep doing #
👍
Thanks a lot brother !!
plz upload more videos....of all gate metallurgy subjects..
By the end of this month...Steel Making will be completed !!
And what happened to the CO2 that is released from the decomposition of the flux?
Same doubt
spr lectures
Sir please update the gdrive link for that folder, it's not opening
What about CO2 released from calcium carbonate??
Friend the link of drive is not opening else it has been removed I want to solve other examples regarding the b.f extraction
Please look into this and share the link thanks😇
Yeah, we are trying to resolve it soon !
The link you are provided is error

@@everythingmetallurgy then how can we will get ans in gate exam because there is wide range of variation when these things are left
Thanks sir
Well explained! thank you
Please make a video on K value.
👍👍👍
1 mole is 22.4 lt. and 1 lt. is 0.001 meter cube. right? but you said in blast volume calculation that one mole is 22.4 meter cube.
Actually we deal with KgMol....so its kilo liters...so it will be cubic meter !!
Mole can be grammole or kgmole, for gmole it is 22.4 lit @NTP n for kgmole 22.4 m3
the answer is not there in the given options!! check it
Which one Bharati Sahu ?
@@everythingmetallurgy volume of Blast furnace gas produced
