I'm working on the blast furnace models for my layout (instead of painting the ceiling like I should be). I can't seem to find a good source on the depth of the runners on the casting floor where the iron flowed from the furnace to the torpedo cars. I'm leaning towards making it a foot deep right now. Anybody have any thoughts or info I missed on the internet? Photos make it look like I'm guessing close to the right depth.

I would think a scale foot (1/4") would be fine for hot metal. I looked at a photo I have for slag cars parked at base of the Weirton Steel blast furnaces. The sides of those troughs look to be 18"-24" high, but that's slag. If you want to go 3/8", you're probably golden.
A deeper slag channel makes sense. I know blast furnaces are hotter than the induction furnaces we ran (because metallurgy of big castings and yada yada eutectic) but I believe slag runs different than iron.
I think 3/8" is probably going to be the ticket as I sit here and think about it. Thanks!
If you watch any of the U tube videos of old time steel mills, it looks like the iron runner has mounds of gravel, slag, something piled along side of it to contain the flow.
