For those of you that don't know, Glenn worked as an Industrial Engineer at the Gadsden Works. Here is a satellite view with some of the buildings I shot and sites for demolished buildings labeled per my 1950s plant map. Obviously, there were many changes made over the years. For instance, the plate mill and hot strip are shown in the same building. A rod mill that doesn't exist today is shown on the 50s map. There are late drawings of the plant on site. Maybe I need to go back and get a closer look at them. Is the building shown as the plate mill correctly labeled? Thanks.

It is interesting that you mentioned coal mining because that is an industry that highlights another modern phenomena. Technology has maintained production levels with just a few mines and light employee roles replacing hundreds of mines and thousands of employees of yesteryear. During 2010, Alabama coal production was about 20 million tons. This was done with a handful of mines and approx 4600 total employees. In 1925 we had hundreds of mines and thousands of men mining coal. Guess what the annual production was? You guessed it, about 20 million tons. As you know, one continuous miner can dig about 5 tons/minute in optimal conditions. A longwall machine, now that is another level altogether. Contrast either to men with breast augers and picks... Production technology has had a similar effect. During the Civil War our local blast furnaces (on red ore) like Oxmoor and Irondale produced 6-7 tons of pig iron per day. Over at USS Fairfield the state's last operational blast furnace (there used to be over 40) currently produces 6500 tons of basic iron per day for the steel mill. That is the equivalent of 1000 Civil War furnaces! If you visit the hot side at Fairfield you'll see very few people there. A handful of men in control rooms and a few on the floor replaced thousands of employees from just a few years ago. Innovations like continuous casting machines streamlined production with far fewer labor hours needed. The point I am trying to make is that many times our output is still relatively high but the job numbers aren't there. Add in environmental regulations/red tape, labor disputes, greedy management and cheap foreign product and next thing you know we're producing 1/10 the steel of the Chinese. Its sad.

My step brother Dan worked in a giant steel mill in youngstown ohio. He gave me a tour of the mill one day I'll never forget. It began where they melted crushed cubes of old cars in large ceramic crucibles which they fed into a molten creek of flowing liquid metal.....they added alloys to and it became more solid but still white hot as it flowed and moved though the plant. Eventually it was cut into long ingots that were spun and first made into rods....then became seamless well casing.....and finally threads were cut onto the pipe sections in another building. It was almost frightening to be in there because there were hazards everywhere. I think it was called a continuous something mill.

Eric,
You have the Plate Mill correctly identified. The building directly north of the Plate Mill was the Trusscon building. I understand they originally built trusses in the building. In my time (76 to 86), it was the Plate Mill warehouse annex. They did rework and heat treating in the building. The building area connecting the Plate Mill and the Hot Strip Mill was the Pipe Mill. It wasn't running anymore in '76. Continueing West of the Hot Strip Mill was the Cold Strip Mill. The HCL Pickle Line was in the building running to the south. Coils of Hot rolled steel were brought into the south end of the Pickle Line and exited in the East/West building. Just to the west of the pickle line was the 2Hi Hot Temper Mill and the Hot Slitter. The next area running to the north was the Tandem Mill. The next bay to the west was the annealing area. The 3rd north south bay was the 4Hi Temper mill. The galvanizing line, cold slitter, and warehouse areas were further to the west. It looks like some of the buildings may have been torn down or added to. Glenn

Thanks Glenn.
Can you give me some background on the 2Hi hot temper and 4Hi temper mills? I kept seeing manuals labeled as such on shelves but the 2Hi and 4Hi terms are new to me. |

The temper mills were to add temper to the steel and also improve the gauge and finish quality. The 2Hi and 4Hi refer to the number of mill rolls in the mill stand.

That is a great shot. Obviously it was after the open hearth days. Any idea when the BOF went online? Thanks for the info on the temper mills.

Eric,
I don't remember hearing when they went on line. The electric furnaces were off line by '76. I'm not sure if they were still there. I never spent much time in the BOF shop. I never got comfortable there so didn't want to spend time there. Spent a lot of time at the Blast Furnace, Plate Mill, and Cold Mill. Found something for your next trip to the Thomas plant. Glenn

Thanks Glenn.
Great layout view of the Thomas plant. The trip we took over there a few years back was fun. We should get together and go to Gadsden someday.
