Metal Casting @ Andrew's [10.20.07]
Zach barth's quest to melt anything that is composed of aluminum into
ingots / something useful.
What do i
blast furnace (how to below)
- Aluminum can's / heat sinks /aluminum scrap
- Welding gloves
- cast iron pot
- Kitty litter (for sand
- safety stuff (mask, boots... etc)
Working with molten metal and high temperatures can result in injury, so protect yourself and proceed cautiously.
|Metal selection note: check out the pdf link regarding metal melting temperature. Its not aluminum if its magnetic
a cheap blast furnace
Note: this entire idea and project was heavily put
forth by Zach, he created the initial blast furnace found an 'anvil
shaped object' and got everyone interested. The success of
this weekend trip was largley to his efforts.
As shown in the drawing, the 'blast furnace' is nothing more than
a turbocharged bar-b-cue that can withstand higher temperatures.
|concrete and a pail
after obtaining a 1 gallon tin bucket and slightly smaller
flower pot, place a few 1" tall rocks at the bottom of the pail. add
the clay pot on top.
next, bore a hole (1.5" wide ) in the clay pot and metal can and place
a short cast iron / steel tube through. Fill remaining area with
||Hairdryer / fan / forced air
using either a hair dryer or some similar device which can
pump large volumes of air through the air pipe, attach to a long 1" in
diameter tube (2 feet long). the reasoning for the long tube is to
prevent the thermal conduction of heat from the furnace to travel back
to the hair dryer.
||light charcol bricklets using lighterfluid, place cast iron crucible (or pot) on top of charcola bricklets.
