Carbon Arc Furnace

Carbon arc furnace,
Electrodes: 1 inch dia. graphite
power: 30V 200A
Enclosure: high density alumina refractory bricks, rated to 2000 degrees C
atmosphere: Argon/CO2 welding gas

after about a 3 min run, the tungsten had not melted.
the furnace was allowed to run for an additional 5 min, after which it had melted the tungsten and a significant amount of alumina fire brick.

i have never heard the words "molten ceramic"

anywhere. ever.

[veryfuck]

what exactly are you trying to do in the video? are you trying to melt tungsten? tungsten has a melting pont of 3400 celsius. if you know how to melt tungsten and make it into a shape with a moulding, i would like to know more.

nice vid, luvd it

doesn't this go way past the duty cycle of your welder? This does give me ideas though.

Yeah, Alumina is also used as an insulator, and is really common in sunscreen (the white color). Simply - the way they make Aluminum out of it is by heating it up, really super hot. Then cooling it carefully.
