Thank you so much. Your slides are EXCELLENT.

Good information thank you 👍

Super video ..Make many videos regarding ,Steel Quality,Heat Treatment.

Nice sir

What is the stack batter? Inwall batter?? What is the purpose of batter???

[@kancharlasiceland5632]

Sir can I know the in detail of second passivation method which is chemical coating method

[@kitsontuli2713]

This came in time for a test I am writing tomorrow, thanks. Any videos on blast furnace refractories?

Thank you, these articles have been helpful

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.

I was seen both 1and2 method
