That was an awesome video! Being an ol bricklayer, and now a Pipefitter, it was cool to see a drone flight over something I'm somewhat familiar with! A little info on what I recognized in your video... And a very very short explanation at that.
It appeared there are 4 separate blast furnaces there on that site. Small in comparison to the 3 that I have got to work on, which was total reline jobs of the refractory inside of them, but so so cool to see! The ones I worked on were huge, one being the 2nd largest in the world. A true privilege!
The tallest vessels are the blast furnaces themselves. That's where the actual melting of the raw iron oar took place. The smaller vessels that surrounded each furnace are stoves which generated the heat it took to melt the iron oar. Amazing how that part works.
Inside those stoves, and on one side are firebrick called checker brick. Air is forced up through the holes in the checker brick then hitting the domed top and coming down the other side. This friction is enough to get the air very very hot. It then enters the blast furnace, in a blast, igniting coke, which is a baked coal dust, thus melting the iron oar that is dumped in the top of the furnace which gave you raw steel. The stoves take turns providing the heated air.
What I'm not seeing is the rest of the yard, which must not be there now. It would've been where the raw steel was taken in a melted form to the big pots where the additives like zink was added.
That plant had to be from very late 1800's or early 1900's. Very old, very cool! I can just see it up and running and all the old timers running it! I just find it amazing the technology they had back then is still used in the same ways today! Today's blast furnaces work just like those did, just more controlled as computers come into play.
What a cool thing to video! I loved your perspective on the things you brought attention to. The POI you done was what appeared to be a stack off one of the furnaces.
Great job and keep it up!
