This looks like you really need to know what you are doing to get the right metallurgy, vs just throwing some scrap into a crucible. I wish I understood more about it and what the advantage is.
I use to have to drop the bottom out of a 110' cupola every night clean up the drop chip out the slag and some of the worn out liner and respray a new liner recharge with Coke and pig iron put the torches to it. So at 7am when the men came in they unplugged that bitch and iron best be ready to pour. In 7 years I had 1 failure. Good union money left our little town in 1988. Sad the all these Mfg jobs have gone over seas. Tioga Casting Facilities in the Finger Lakes of New York .Was a good paying job back in the day. We need this kinda Mfg to come back to the states IMO.
The same thing has happened in Australia. There were two foundries close to where I live and both had cupolas now there are no foundries close to where i live.
You do realize that cupola furnaces are not legal to melt in the us? Too dirty! Besides that, you did not explain anything. For instance, scraping off the slag while pouring. Also the importance of a continuous pour when pouring so as not to ruin the casting. Another thing, what and how was the cupola filled or packed with material and what kind of material. I.E. Coke? Pig iron, scrap iron, iron oxide? And what proportions?
Cupolas are in no way illegal to fire. The emissions are regulated yes but he's not doing it commercially so no laws being broken (or at least no one cares). I also do not beleive he is in the U.S.
Nice little cupola it's nice to see other people running these things. However most people don't realize how labor intensive a cupola is.

Boy, I wish you responded to comments, I've so many questions, Any advice for someone wanting to build his own cupola?
Good to see this interesting work. What is the hearth diameter? Can you share information on melting rate please?
225 mm Dia. melts approx 200 kgs per hour.

It is so interesting, the quality of the cast iron - is fit or tolerable?
Are y'all tapping then putting the preheater back on till y'all get a full paddle?
Does iron shrink as much as aluminum when it cools?
Just pour it already slag is your friend. Geezes the guy with the thermocouple is in the frigging way
If you don't mind my asking, what's your foundry sand mix?
Great video!!! man...
Ох. Так это же варганка. Я давно не видел чтобы их использовали.
I dont think the sound made it into the video bud

Why would I want to charge iron oxide into a cupola? It shows that you do not know much about cupolas to ask a silly question like that.
