Perhaps some of you have already been puzzled by the smelting of metals.
In this article, the author of the YouTube channel NightHawkInLight will share with you a simple field melting technology for aluminum.
Materials
- Aluminum scrap metal.
Instruments, used by the author.
- shovel
- small fan
- steel strip
- Pan.
Manufacturing process.
The first thing to do is dig a shallow hole in the ground under the fire. The flames and the coals themselves will be slightly below the surface of the earth. Thus, the heat will be better preserved, less blown away by the wind, and less smoke will be formed. By the way, cooking so much easier.
The pit is about 60 cm in diameter. It is important that its walls are vertical and that it does not taper towards the bottom. So, the depth is not 90 cm.
The fire needs a constant flow of air and so that it burns well, being located below ground level, the author tears out a narrow tunnel at an angle a few feet from the campfire so that as a result the tunnel intersects with a pit under the fire in its lowest part, at the bottom .
All the soft clods of the earth are removed from the pit and the tunnel, after which you can begin to light the fire
The air vent provides sufficient airflow to maintain intense clean combustion. Later, the author will install an additional fan at the entrance to the tunnel for greater air injection.
As a crucible, the master takes an inexpensive stainless steel pan. In order to melt this metal, it will take an order of magnitude higher temperature than that needed for melting aluminum.
The author takes soda cans, they are made of aluminum. And some aluminum chips left after turning. But you can use any other available aluminum resource.
To keep the pot over the fire, the master uses a steel strip, which is threaded through the handle of the pot.
The fan has a propeller in the ventilation hole and secures it to any stick, PVC pipe. This project uses a small fan that can safely operate on a small solar panel. However, you can install a larger propeller, then the flame will flare up even hotter.
As aluminum cans melt, more space is freed up in the crucible and the opportunity arises to add more raw materials.When the pan handles fell off the rivets, it turned out that they were made of aluminum. But the process did not stop there.
I had to put the pot directly on the fire.
Out of sheer interest, the author decides to pour liquid aluminum into a previously prepared hole in the ground.
The moisture present in the earth has led to the appearance of several bubbles. It is worth taking this effect into account.
Thanks to the author for the simple idea of a stove for melting aluminum, and cooking.
All good mood, good luck, and interesting ideas!
