Scrap

The mini mill steel production process begins in rather unassuming surroundings – the scrap yard. Unlike conventional integrated mills, which rely chiefly on coke and iron ore, Nucor uses 75-90% scrap steel as its “raw material.” More...

Electric Arc Furnace

The charge bucket is filled with scrap steel and scrap substitutes and then transported to the Electric Arc Furnace (EAF). Direct Reduced Iron pellets, which make up 10-40% of the metallic charge, are conveyed through the roof of the EAF shell to diluting the residuals to acceptable levels for the required end use product.

Ladle Metallurgy Furnace

Before each heat goes to the Continuous Caster, it is processed at the Ladle Metallurgy Furnace (LMF). Unlike the EAF, which is a DC furnace with a single 28" carbon electrode, the LMF is an AC furnace with three 16" carbon electrodes. More...

Continuous Caster

Shrouded steel drains from the ladle into the tundish, which serves as a reservoir allowing multiple heats to be sequentially cast. The steel flows from the tundish into the mold through the submerged entry nozzle or the SEN. Nucor Tuscaloosa has a variable width mold capable of "in bar" width changes. More...

Hot Mill

When a slab is properly heated, it is extracted from the reheat furnace, descaled, and then enters the steckle mill for a series of rolling passes reducing it to the desired final thickness. Our mill is unique in that it performs the roughing and finishing passes with one reversing Four High Mill Stand. More...

Temper Mill

For a plate product ranging in thickness from 3/16" to 3/4,” coils are produced and scheduled for temper passing at the Cut To Length Line. The line features a state of the art four high temper mill with hydraulic automatic gauge control. Coils are loaded on to a laser guided coil car and driven into position. More...
