The Wiggly Wizard posted:Is this person causing excessive air and water pollution compared with a large aluminum recycling operation? Are the thing she forges safe to use or are they going to poison you and shatter? She's casting something, forging involves hitting it after. I've been out of manufacturing for going on a decade so pardon some foggy memory here: We can't know what she's firing the furnace with to answer that, but aluminum cans are usually made from 3003 aluminum IIRC so the aluminum itself is fine. I wouldn't expect them to be of meaningfully different safety than any other aluminum casting, but I haven't given it much thought. That alloy can't be heat treated and I'd think you can't really mechanically work it once cast so it'll be used in the -O condition (as cast). Generally this would be fine. It's hard to know if there are impurities or intermetallics from other alloys that'd cause it to be brittle but I'd be surprised if it shattered from normal use. Definitely not a safe working environment though, that it a large molten pot of metal she's carrying around.

The most poisonous part of that whole situation, I'd imagine, is the fumes from the epoxy coating on the inside of the cans and the paint on the outside burning off.

Right this is partly what I was getting at. Is it all getting burnt off or is there going to be ashy residue mixed in

We have a park next to some busy locks (although not as busy as those), and it's really nice to sit there and watch all the boats come through.

GotLag posted:Does the paint on the cans just burn off as they melt, or pool on the top/bottom of the crucible? I watch lots of smelting videos and they usually add borax and skim the slag from the top before the casting, so it seems most of the dross either vaporizes or burns to ash.

Metal is much more dense than the organic dross, so simple settling achieves pretty good seperation.

CarForumPoster posted:She's casting something, forging involves hitting it after. Yeah 3003 is an alloy that doesn't heat treat or age so it's traditionally cold worked which is what then develops its strength and stiffness. Mostly it's used from sheet or extrusions and then rolled or pressed or drawn/deep drawn to get it to final shape and size which cold works it a lot to do thst. A lot of stuff like stamped flatware or bowls or serving dishes (note: that are aluminium, I'll be honest everyone uses 304 stainless these days) are 3003 for that reason. Honestly as backyard castings go it's not the worst I've seen, the biggest risk I can see there is their moulds getting wet since they're stored outside since it doesn't look like they preheated or dried it before they poured. I suspect as well they'd get porosity on the corners where the bowl changes angle because that's going to be where the metal pulls as it cools I think. Something thet thin is going to be tricky to get to cool towards the riser uniformly.

That is really neat, I didn't know they stacked in multiple ships at a time. Although to be fair, I've only actually seen smaller river locks in action (also entertaining when a lone canoer showed up and got let through)

As other posters have said though this stuff will mostly turn to dross and be carried to the top with the aluminum oxide. That’s not to say this is a good idea, it’s a risky process and the wrong alloy for making a decent casting but idk if it’s destructively bad in some way. Certainly it takes way less energy to reuse cans straight away than to try to refine bauxite into virgin aluminum.

Bauxite takes an absurd amount of electricity to refine, this is an excerpt from an article about aluminum production in the PNW:quote:The Columbia River has a key role in the history of aluminum production in America, as the industry was the first major industrial customer of Columbia River hydropower. Over time, the industry grew to employ around 11,000 people in the Northwest and consume 3,150 average annual megawatts of electricity, enough to light three cities the size of present-day Seattle for a year. Aluminum, however, is very easy to recycle, my girlfriend's in the can-making industry, and they've been unable to keep up with growth over the last three years, from a combination of the pandemic making people drink more beer at home, and companies showing more interest in sustainability (well, greenwashing), cans are being imported by the millions from the Middle East and Brazil.
