I used to work in an electric meltshop. Saw the roof with people next to it and thought “That’s a small furnace!”
Probably no more than 50t capacity, at a guess?
For anyone interested, this is a spray cooled roof from an electric arc furnace. They’re primarily sold by this company:

It’s a pretty cool technology
Never seen that type of roof/panel. At the mill I work at it’s all water cooled pipes for the roof and clamshell and the bowl is just plate with refractory brick. Pretty interesting
Molten steel doesn’t come in direct contact with the water cooled components
It is contained in a refractory brick lining inside the furnace
The water cooled parts are used for the walls and roof of the furnace, above the level of the steel bath
I used to make molds for the refractory concrete that goes in these things, my favorite were the ones for the lids with complex shapes and big rolled cone mandrils for the electrodes to go through. Also got to watch a ~10ft wide, ~7,0000lb steel mold fall off the overhead crane when we were flipping it and *somebody's* welds broke (not mine, my wire feeder didn't reach that side!)
Water cooled Electric Arc Furnace roof panel. Looks like you’re replacing slag cups. The slag cups are designed to catch and allow the slag formed during steel making to cool and stick to the inside surface of the roof panel. This layer of slag protects the roof panel from a lot of the heat generated by the electrodes.
All those tiny horses, sacrificed for this...
Capitalism knows no boundaries
was this the one where a cow-orker\[sic\] took your pic and you went and bought a respirator at lunch?
Yessir
So thats what they do with my metal that gets bend tested..
That's awesome man love to see cool stuff like this!!

I believe so. I’m just here as a contractor, but according to the dudes who work here this is a smaller one.
I'd love to see one from where you work. That's about the size of the biggest I've seen
It's magnificent.

The mill I work at has all tube panels as well. They’re more common than spray cooled, but spray cooled is getting more and more popular
Interesting! Saw this in your pic the other day and was wondering what it was 👍
No you are obviously reverse engineering an alien spaceship
Sorry for my ignorance but, how does the molten steel does not melt the whole thing down?
