Steel Manufacturing Process: Coal & Coke
Vložit
- čas přidán 27. 08. 2024
- Coal is a mineral consisting mainly of sedimentary fossilized carbon with smaller amounts of other elements, such as sulfur, hydrogen, oxygen, nitrogen and more. Coal is found under the earth crust as lignite, or brown coal - the lowest ranking coal, bituminous coals and anthracite. It is extracted either from underground by shaft mining or at ground level by open-pit mining.
Coal is the largest source of energy for the generation of electricity worldwide and is also used in the production of metallurgical coke as blast furnace fuel. Some smaller blast furnaces can utilize charcoal as a carbon source, but the larger blast furnaces require the strength and durability of coke.
Coke is produced by igniting bituminous coal under reduced oxygen conditions in oven batteries specially designed for this process. The coking process generates the following main volatiles as byproducts: coke oven gas, tar, ammonium sulfate, benzol, toluol and naphtha.
A coke battery is made up of multiple ovens. Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called “coke” remains. The coke, when exposed to oxygen, will immediately ignite and begin to burn. When the coke is pushed from the oven into a railcar, it is quickly quenched to cool the coke and stop the burning process. The cooled coke is then dumped onto a coal wharf where it is taken to a facility to be screened and sized prior to being charged into the blast furnace.

Thankyou for such a direct and comprehensive dialogue which explains exactly what is happening during the animation, so detailed and helpful, amazing
it’s a 1min video..
@@levetbyck yeah no fucking shit 🤦🏼 that's my whole point, 1 minute and summed it all up unlike other videos that take an hour to explain the same concept 🥴🥴
@@llll7396 but the video doesn’t tell you anything - it just shows coal being heated and transported that’s it!!! (unless you want us first to read the info about the coke batteries in the video description..)
I wasn't sure what was going to happen to the black things, but when they turned red I knew everything was going to be alright.
*IT'S A BIT TOO LOUD. COULD YOU TURN IT DOWN A NOTCH? Thank you!*
😂
🤣🤣🤣
😂😂😂
Excellent voice over thank you

This is a video of a battery in a coke oven plant.
The coke oven consists of multiple ovens each with 2 doors on either side of the battery.
The machine on top of the battery is called a larry car. It's job is to fill up the ovens as you can see. The product “cooks” for 24 hrs.
When it's done cooking it has to be taken out of the oven.
A pusher machine removes the door and their is a door machine on the other side that's not pictured that pulls off the door on the other side.
The pusher than pushes out the product to the other side into what's called a hot car.
That hot car then goes to the quench station to cool off the product.
After that the hot car drops the product off at the wharf
I like the animation...but I still don't really understand the process. Some text explanation or narration would be helpful.
silent movies are better than looped music> but some explanation would, be helpful!
I agree with explaining this carbon creation. Why coal why burn off the Petroleum out coal and not use the energy coal has.
I first learned of this in Alberta Canada. They make coke in a 27 story tower but the Petroleum in coal is captured making oil, methane gas recovery. Why don't they add hardwood sawdust to the creation of steal. Less toxic to the earth.
I know nothing about this but because of that I want to know it will drive me nuts till I know. Johnny 5 Alive

@@ProtruckR Coke is also used to add carbon to the steel mixture. Carbon gives steel resilience and toughness but decreases the weldability and flexibility of the metal. This type of steel is what you see in automobile chassis, building foundations, and applications where extremely strong steel is required.
Specially selected Coal is heated in a oxygen deprived environment within the oven for 18-24 hours until it is turned into coke. They do this to get rid of almost all of the impurities, and leave behind a mostly carbon product. Then it is used as a fuel to help add heat, reduce iron oxides, and help with structure in the molten material itself.
@@Clone003 Thanks for the great explanation. I remember posting this a couple years back, but I couldn't figure out why heating/burning the coal would make it into a better fuel. You pointed out the oxygen deprived environment, so that makes sense!
Very good explanation
Thanks for liking Pasula.
A coke battery is like working in hell, fumes, heat, smoke, tar, you name it. The by products are very toxic and the piping is made out of lead. I was apprenticed as a welder at Youngstown Sheet and Tube and pulled maintenance shifts in the battery. The workers on top of the battery wore wooden shoes!
Not to mention the asbestos you probably inhaled as well.
So this is how you make black cheetoose , i see
Heres what i see . I may not have the right technical terms, but this is the jist.
Coal is loaded into the coke oven and, for want if a beter word, cooked until it becomes coke . It is pushed out of the coke oven into a hot hopper and taken to the quenching tower where it's cooled by water . The hot hopper moves out of the quenching tower, and the coke is released for loading into a train to take it where it's needed .
Sir mujhe ek question haa ???? The pure form of carbon which is manufacturing of steel
Dear Sir,
Can we download your video and use it for educational purpose?
We'd prefer that you link to our Steel Wheel videos on AIST.org. There are descriptions for all of the processes.
@AIST186 this is a terrible video with no explaination
Superb got the operation
thank goodness
After the coke is dumped onto a coal wharf how is it transported and what's the building called where it is taken to be screened and sized.
Where I work, there’s a machine that takes the coke on to a conveyor belt where it is taken to a screening station and shaken separating the breeze from the larger pieces and then transported to where it needs to go by conveyor belt and trucks
Кокс с рампы попадает на транспортерные ленты,и идёт на коксовую сортировку,далее грузиться в вагоны
obrigado
Just got here after watching a reel from TATA Steel Industries. They are shutting down their operations. I feel sad about the workers.
What can you do with metallurgical coal besides for stell making? Ty
I don't understand whats going on and why...you heat it up then cool it down then throw it out ....ummm What?????

By subjecting coal to such high temperatures without the presence of oxygen, you can alter both the structure and composition of it, turning the coal into coke.
There are two primary benefits:
1-More pure carbon content: If the fuel and carbon source used in steel making is slightly higher in impurities like sulfur, it can have drastic effects on the properties of the steel. By creating coke, such impurities can be driven off to a very high level.
2-Alteration of the Physical structure: Another key thing is how the internal structure of the coke impacts the burning within the furnace. The increased internal surface area help in it's usage in steel making(not sure on the precise mechanisms(better burn?)).
Without voice dont understand
Hi Rezwana. This one is best viewed on AIST.org/SteelWheel
There are descriptions for all of the videos.
Thanks 😊😊
Excellent animation...
No sound
Amazing
What software do you use to create animation?
Alien 3 ending
lol
Very good bout i dont give eny informatoin about nerdel cok
Like show the coke oven gas too,
They dont show the humans that work it suffering and dying from all kinds of cancers when they retire... the nastiest job in the steel making industry...
Should be a tiktok thing
Man good thing I can read lips 🤷
WHAT!?
Why are all those turds in that tank
weird comment section, buncha bots
Very Dwarf
How to get the contact num for this i need carbon coke
I have this source of coke, please contact whtasapp
that some funny looking soda
Oh my god! I'm deaf!
This process is killing the earth
I know right, some narration or, God forbid, sound would be nice
Shut up you hysterical muppet.
The earth was warmer with more co2 in Roman times .... How do you explain that ??
Why didn't the world end back then?
Because it's all cyclical and normal you hysterical gullible chump....
How is it killing the earth?? Explain please??
What a load of crap
