I create this post because I am working on a little project and I have to deal with a problem but I can't find any solution.
Indeed, I 'm trying to make a little electric arc furnace, to recycle some metal scraps. Unfortunately, I can't find any carbon electrodes. Obviously, I can buy some of them through the Internet but the delivery charges are too expansive for me. Moreover, I think to make my own carbon electrodes would be, well, cool
So I tried different options to make a carbon electrode :
-zinc-battery : I cannot find any of these battery in shops
-charcoal : I was very surprised, it is an electric insulator
-carbonised cotton : It is a good electric conductor but it is also too fragile
-graphite from pencil : it just explodes on my face because of the current...
I think I will try to carbonize some plastic parts, maybe the result will be interessant. But if you have any advices, please please please, tell me
I have been stucked on this problem for a long time, and I really want to success this project.
Thank you in advance. Oh and I'm sorry if my english is a little bit bad, actually I am French
