嘿 伙计们 后院的科学家们
Hey guys, backyard scientists
今天 我要向大家展示
Today, I’m going to be show you
如何制作你自己的铝冶炼厂
how to make your own aluminum smelter
我从邻居家请来几个小孩
I’ve invited some kids who are from my neighborhood
我跟他们说如果帮我做新的火炉
I told them if they help me make my new furnace
就把旧的送给他们
They can have the old one
我是杰斯
I’m Jace
我是卢克
I’m Luke
让我们开始吧
Let’s get started
好的 我们现在只用两种材料
Alright. We’re only using two ingredients
你可以在五金店找到它们
and you can find them both in the hardware store
你只需要买
The only thing you need to buy is
硅酸盐水泥或者任何种类的混凝土 是的
Portland cement or any kind of concrete, really
还有一包珍珠岩
and a bag of perlite
对了 还有一样材料
Oh yeah, there is one more thing
这是可选可不选的 但是
and this is just optional but,
我带来了类似泰瑟枪的手杖
I brought along Taser cane to help
激发两位小伙伴的积极性
keep my volunteers motivated
你需要做的第一件事是
The first thing you need to do is
把一包珍珠岩倒到一个桶里
pour out a bag of Perlite into a bucket
然后往里喷点水
Then spray with some water
你要保证珍珠岩是湿的但没有完全浸透
and you wanna make sure that it’s wet but not soaking
这样它就不会从混凝土混合物中吸收水
so it doesn’t absorb water from the concrete mix
记住它们的混合比例
Remember this ratio when you mixing it together
每包珍珠岩
For every one bag of Perlite
配合20-30杯水泥或
you use at about 20 to 30 cups of cement
混凝土使用
or concrete
我们现在可以混合了吗
Should we be mixing this?
把混凝土和水混合到一起
Mix up the concrete and water
现在进行下一步
and now the next part
这一步有点难
It’s kind of hard
是时候混合混凝土和珍珠岩了
It’s time to mix up the concrete and Perlite
来回搅拌少量的混凝土和珍珠岩
Just mix the concrete and Perlite back and forth
直到二者融合
in small quantities until it reaches an equal consistency
快干活
Get to work
你要保证它不会太松软
You wanna make sure that it’s not too runny
要像特别厚的结实的饼干面团
but rather like the super thick, chunky cookie dough
可以用手分开
Something you can break apart with your hands
但又能形成球状
but still put it into a ball
在底部垫上几寸厚的混合物
Put down a couple inches on the bottom
然后放到你弄成的形状里
and then put it in your form
开始填满一直填到顶部
and start filling it up to the top
保证美观和紧实
Make sure everything in there are nice and tight
混合物中没有大的颗粒
there is not big boys in the concrete mix
然后让最上层变得平滑 使表面美观
Then smooth it up on top to give the nice surface finish
我觉得很棒
I think that’s good
好了 现在通过铸造把它们弄干
Alright, while the foundry is drying
我来展示一下怎么做成丙烷燃烧器
I’ll show you how to make this propane burner
这是你能做成的最简单的丙烷燃烧器
This thing is about the simplest propane burner that you can make
我在五金店看到这些
I saw these hose that connects to the
连接丙烷箱的软管
propane tank at the hardware store
我们只需用末端连接丙烷箱
We only need the end that connects to the propane tank
所以你可以把它们的末端切下来
So you can just cut these on their end off
找一些几寸长的铜管
Get some quarter inch copper tubing and
把他们连接到软管开口的一端
stick it into the open end of the hose
来做成丙烷燃烧器
to make to propane burner
我需要做的就是切掉
all I need to do is cut the end of the copper tubing
铜管写着供应商的那端
with suppliers
切铜管时
When you cut the copper tube
确保不要一直捏着它
make sure you don’t pinch it all the way
你可以让它有个小小的裂口
You want a little tiny slit in there
这会使丙烷气体高速的喷出
This will allow the propane gas exit in the high velocity
然后带动空气进去
and pull other air in with it
现在这些软管的内部表面
Now these hoses may have a safety feature
就完全封闭了
on the inside of them
这里有小的校准器或者活塞
There’re some kind of little regulator or plunger here
你刚打开丙烷阀门时可能会有拍打声
That slap shut if you just open the propane valve
我拿一个钻孔机钻开 让他不那么封闭
So I just took a drill and I remove that safety feature
这太简单了
It’s super simple
你只需要两根管子
You’ll need two pipes
一个插到铸造口
One that fits inside the foundry
另一根连到这根管子上
and one that fits in the other pipe
把小管子抽出来一点
Pull the small pipe out a little
然后它会在铸造炉内发出闪光
and then it will kind of feel like a flare on the inside of your foundry
现在通过推动铜管来调节火焰大小
Now adjust the flame by pulling the copper pipe
直到你能看到这样的情形
in and out until you get something looks like this
这是我做的丙烷燃烧器
Here is the propane burner I made
这是我在易趣网上找到的80美元的丙烷燃烧器
and here is what I found on eBay for about 80 bucks
我的燃烧器并不完美 但
My burner is not perfect but
他肯定要比80美元便宜
It is sure cheaper than 80 dollars
如果你按我的方法做成了燃烧器
If you did make my burner
你只需要稍微打开一点
You’ll need to open it up just a little bit
但所有事物是一个个小的考验 我们会犯错误 所以
But like everything there is a little bit of trial and error involved, so
就像这样
Like Ramset
我用了一个大的钢管当成坩埚
I use a big steel pipe for my crucible
但你可以使用不锈钢管做成的其他东西
But you can pretty much use anything made of the stainless steel
小心地插进去 以防刮到水泥混合物做成的
Insert it carefully so you don’t scratch the delicate refractory
耐火材料 然后盖上盖子 保持热度
cement mixture and put on the lid to keep the heat in
这是我铸造用到的铝
These are the aluminum I using my foundry
它是用来做你
It’s for electrical wires like the
抬头就能看到的那种电线的
the kind you see overhead
只需几分钟就可以加热到铸造温度
It only takes a few minutes for the foundry to heat up
10分钟左右 铝融化
and then only about 10 minutes for the aluminum to melt
完成后坩埚内就是融化的小铝池
After there is a pool of molten aluminum in the crucible
现在一切进行的更快了
everything will go a lot faster
我已经告诉你怎么把铝融化
Well, I show to you how to melt the aluminum
现在由你让它做些什么让它冷却下来吧
now it’s up to you to do something cool with it
不要冷却太快
Just not too cool
别把我晾在一边
Don’t put me out of business
好了 去做吧
Well, there you go.
现在你知道怎么铸造自己的铝了
Now you know how to make your very own aluminum foundry
如果你用它做了别的东西 我很开心
and if you ever make anything with it, I’d love to see it
