What did Horsehead make at that plant? Ingots, shot? I assume they had a few smelters.

Various size ingots from what I can remember. I do remember someone mentioning that the zinc could eventually end up in breakfast cereal.

I work for a galvanizing line (continuous HDG for steel sheet, not just dipping in a kettle) so your comment caught my attention. We typically use the 1 ton ingots to replenish our bath. Between my line and our two sister lines in the area we're probably using 50+ tons a day.

Would that be considered a "drap line"? My dad snuck me into the steel plant in Midland and showed me that new continuous line. The craziest part were the smelters though.

I'm not familiar with the "drap" verbiage. If the plant you visited had smelters for steel it was mostly likely a large integrated mill and you were in the melt shop/LMF section. I think ATI (stainless sheet) has or had a plant in Midland, PA.

Continuous hot-dipped galvanizing lines are smaller in comparison. If the plant you visited had a pot/kettle that they were feeding zinc ingots into then it was a HDG line.

The terminology for DRAP lines would be as follows; Direct rolling, annealing, and pickling.
