A prototype rolling mill building by itself is typically 1/2 mile long, which translates to ~30ft in HO scale. And there's usually more than one of these, so the company can process different shapes (sheet, billet, rod, etc.) without retooling.
A basic oxygen furnace building, done properly in HO scale, would need to be roughly 6ft long and 4ft wide. A blast furnace by itself might not demand much space, but once you add in the blower house, ore stockpiling/loading, coke processing and other supporting facilities, the need for space really grows.
Also, don't forget all the extra real estate you would need to accommodate all the rail curves going into the ends of these mill buildings - not to mention the car shops and loco terminal (most mills had their own railroad for in-plant switching).
So that's why I limit myself to showing only a handful of the signature structures. If I didn't severely compress my mill complex to fit on a 12ft by 6ft peninsula, my entire garage would be completely filled up before I could even do it justice. I'd prefer to have a little bit more variety (main line, small towns, etc.) on my pike .
.5 mile wow....guess I better figure out a way to gain that 30ft span so i can proper model the mill complex as now i got a switcher (chessie system)
