nice ppt
Super vedio
Nice sir
Thank you so much sir.. Sir i need this pdf.
Thanks for information.
Very well articulated....thank you sir
Sir You are reading only you should explain also
You are knowlagable sir
Sir kindly explain briefly bending in hotroll
Imagine the Evil that would even assume Reduced Iron is ready for human consumption. Must be China logic or the Devil Directly. Still dont know yet. Take reduced Iron from human foods.
That should be implemented at Arcelor-Mittal Hunedoara, Romania plant. Near Hunedoara are two iron ore mine sites that were shut down in 2005. There is still plenty of Siderite and Limonite close to Hunedoara at Teliucul Inferior, Ghelari and Vadu Dobrii.
Good information thank you 👍
sir i want to contact you for learning about process of ferro . is there any way i can contact you
Informative nice
Thank you, very good material about blast furnance and its parts.
Sir what are the reason of MBS Head-Off
Great video👍
Where is the link to this article???
No explanation only reading, that a kid can also do
What is the stack batter? Inwall batter?? What is the purpose of batter???
Can you make a material balance og BOF sir please thank you.
Pls tell about burden distribution on blast furnace performance sir
Kindly read the concerned article on the website ispatguru.com
Binders improve pellet green strength in the production of iron ore concentrate pellets. And the one that solves the purpose is Sodium Bentonite clay, which has higher water plate absorption along with superior Thermal Stability. Here is the more information elementsindia.com/bentonite-iron-ore-pelletization/
Please make composition making of steel mild steel
Thnx🙏🙏

Plz send me pdf, sir
Dear all, I am I. I.V.SUBBARAO from Raghuvamsi Technologies., A. P. I have developed iron ore DRI Pelletization technology(ROTARY KILN BASED SINGLE STAGE DRI PROCES TECHNOLOGY, RELEVANT TO MINERALS, METAL, METALAGRY AND STEEL )without adding of bentonite, coal limestone, dolomite, and it was patented. IPR has been granted of novel innovation patents on 31st Dec 2018. I would like to Commercialize this technology. I am searching for technology commercialzation funds. I am interested in JV,PE, Technology Transfer, Technology sell also. Thanks and regards, I.V.S.Rao. 9490188826, 7569160194. Mail ID:rvit_2007@yahoo.com, raatech12@rediffmail.com
Sir, please post on balling disc. Also chrome pellet sintering in shaft furnace. Basically Co burner.
Nice 1
Thank you for your presentation and knowledge sharing.
Wow
Not good...don't waste time here
The re-oxidation of DRI with water (8.20) does NOT produce excess heat to the point of overheating and meltdown in piles, silos or ship holds. This extremely erroneous statement is at the core of the cause for human deaths in the course of handling this material. It is unfortunate that this unscience is still being perpetuated within the industry.
Why is that wrong? Of the dri is very reactive and is exposed to sea water during the navigation let's supposed, of course that will self heating and also will release hydrogen which will create an a flamable atmosphere and if any source of ignition or spark get in there, good bye ship
This commentary disagrees with some content in the video - Direct reduced iron and production of DRI part 1. Comments are based on findings from a long running Study of Direct Reduced Iron Fires that began in December, 1987. It is referred to as the Study hereafter. ' Industry' refers to the Direct Reduced Iron Industry. Content of the slide in time frames from 7:57 to 8:45 is highly regarded in the DRI fraternity as 'Industry Science'. This information can be found in all the Industry's technical literature on the DRI heating up phenomenon. The video's slides contain broad generalizations without specificity of reaction mechanism, activation energy or equilibrium states. Content is either partially wrong or patently incorrect. It conflicts with the scholarly literature that looked at temperature rise in micro-thin iron films in environments equal to that of DRI and the findings of the Study, both of which are in agreement. The Study's data was compiled from detailed observations of DRI anomaly events and experimentation. Experiments were carried out in either a laboratory setting or went live in real plant conditions. Both Study findings and the meta-analysis of the scholarly literature identified two distinct temperature ranges; a low temperature range driven by the water/corrosion processes and a high temperature range controlled by the oxidation processes. Both are activated processes and are several hundred degrees (C) apart. Below specific temperatures neither of the processes enter into its self heating propagation model. The maximum temperature attained in the water/corrosion, low temperature process is well below the activation temperature required to initiate the high temperature oxidation processes. The third point on the slide in time frames from 7:57 to 8:45 is scientifically impossible. "The re-oxidation with water …. can cause overheating and meltdown of DRI in piles, silos or ship holds" is fundamentally wrong. It is invented science. The Study has been confident of this since 1987. Procedures and practices developed by the Industry for the safe carriage of DRI over land and sea premised upon this false statement introduced more risks with more grave consequences.
awsm sir..
Sir, please give the lecture of heat balance in iron ore sinter
