Overhead giant cranes. Oxyen Lance furnaces being blown...furnaces turning down for temp and met samples. Huge jackhammers cleaning the rims of 150,000 lb ladles.
Ladles being skimmed of slag..or sometimes not, hoist bays lifting 600,000 pound ladles of steel up into the continuous caster.
The sound of a huge 3-phase electrical arc off 450,000 pounds of steel in a ladle in an LMF, a ladle metallurgy facility, where the steel can be adjusted to exact spec and temperature just before delivery to the continuous slab caster. Three furnaces in building to the right side of the photo...Daisy, Evelyn, and Mary.
Heats pour to the west (left) in the lower area, and the the next building is the ladle metallurgy facility, where steel is brought to stable conditions, as perfect as can be. The steel has been skimmed of slag, covered with 200 lbs of vermiculite, adjusted to a perfect 2875 degrees farhenheit for casting the worlds cleanest non gas-bubble inclusion steel.
Got it?
Been that way since the mid 70s.
Here is where the best steel in the USA comes from.
