This is the Amanda Blast Furnace of AK Steel in Ashland KY. As an engineer doing consulting design I work in a lot of various industries. We have installed equipment on the downstream rolling mill section where the final steel sheets come out. This blast furnace runs 24 hours a day seven days a week to produce the molten steel that is then carried over to the casting mill where large slabs are produced.
This looks like a dirty old piece of equipment, which it is. It was last updated in the early 60's. But if you show up at the plant early in the morning before the sun is up and get to see the 50 foot tall blue flame blasting out of the top it is a sight to see.
If you have anything made of steel this is how it started out.
