Many years ago, I was doing an internship at a foundry — the same one from this story. Basically, my college required me to work as a line worker in some kind of industrial plant, and I wound up at a foundry for six to eight months. It was an education; I learned a lot of things about the real world that I really hadn’t known before, which was the point.
At this point, I was “tending furnace”: feeding metal into the furnace that melted it down for the molders to ladle out and pour into the molds.
On this particular day, I started work at about 14:30 and went straight into working steadily. I noticed that the night plant manager was around much more than was normal, but I didn’t really think about it.
Then, a couple of hours into the shift, I had everything set up for the rest of the shift. If I did any more preparation, I would have too much stuff laid out to finish before the end of the shift. So, I went to working two minutes out of five, as was my normal practice.
If I tried to do something else, I would be away from the furnaces too long, which would allow the temperature of the pool — the reservoir of molten metal — to cool excessively, which would cause cold shuts and porosities, which would result in unusable castings. It doesn’t matter how much product you make if it isn’t usable — a concept that too many managers never grasp.
So, I was set up for the evening and waiting for the next moment I needed to do something. Later in the shift, there would be other things to do, but at this time, everything was ready.
And here came [Night Plant Manager], who promptly jumped on me about not being VISIBLY busy. I was puzzled because this was not at all his usual style.
One of the early things he came up with was ordering me to charge the heap of fines (sawdust, floor sweepings, small trimmings, etc.) and flux into furnace #4.
Me: “Well, okay, but…”
I opened the door on furnace #4, and he gasped.
Night Plant Manager: “That’s going to overflow!”
Me: “No. It will handle that okay, but if I put much more in, it will overflow — and I don’t know exactly how much more.”
For the last week or so, I’d been using furnace #4 to “cook down” fines mixed with flux, so I knew quite well how to extract all of the possible metal from the fines.
Night Plant Manager: “Well, clean up all these barrels of… Where’d all the barrels go?”
He started looking around for the barrels of fines and small castings that had been shoved in every corner.
Me: “I emptied them and sent them to the yard. That’s part of the tail end of the fines in that pile.” *Points to the pile of fines mixed with flux behind furnace #4* “I can run that through tonight and have it all melted by the end of shift.”
Night Plant Manager: “Well… then… flux the furnaces!”
Me: “Okay…” *turns away and then turns back* “…but I thought couldn’t do that until after dark.”
Night Plant Manager: “Um, well, yeah…”
For everything else he came up with, I’d say, “Okay, but I thought…” and he’d have to agree with why I wasn’t doing it at that time.
He spent approaching two hours trying to find something I could do without adversely affecting my primary job of providing the molders with metal at precisely the right temperature… and he couldn’t. (I kept interrupting to put metal in the furnaces, walking down the row tossing this amount of metal into this furnace and other amounts into other furnaces; I knew what each furnace needed to keep it balanced and running properly.)
I also explained part of the bargains I’d made with the day shift to divide the work up. One of them was that the day shift would run all the coarse scrap they could, and I would run the fines and small castings and make weight off ingot.
At my dinnertime break, I commented to a coworker how irritable [Night Plant Manager] had been.
Coworker: “Oh, he’s sober today. Don’t worry about it; it won’t happen again for several years.”
[Night Plant Manager] was known to be a functional alcoholic. When he was drinking he was a good manager. (Among other things, one night, he sent me home — on the clock — because I’d had three close calls that night due to someone else screwing up and he wanted me out of his plant BEFORE someone got hurt.)
When I gave notice, I got a week to instruct my replacement on how to do the job the way I was doing it; they wanted that to continue. Normal practice was to wait until the previous furnace tender had left and then have the foreman — who wasn’t all that good at furnace — spend a few minutes instructing the newbie. (Granted, many times they got no notice at all; somebody just didn’t show up for work.)
I found out later that the man who bought our slag for reprocessing into aluminum had told the owner that they had someone new running furnaces in permanent mold.
Buyer: “Two of your furnace tenders give me lots of metal, but this new guy doesn’t give me a d*** thing — and I think he’s reprocessing part of the other shifts’ slag if they leave too much metal!”
He was right. I WAS re-cooking slag that had too much metal — sometimes two-thirds of the slag weight was metallic aluminum.
