Iron melts at 1538C and the copper melts at 1084C so you cannot get melted iron without melting the copper electrodes; i thing you succeeded melting some sand using iron conductivity.
Hello RODALCO.... Are experimenting to find a process to produce pig iron , or cast iron? Carbon introduced into a iron oxygen atmosphere should work to remove the oxygen , thus reducing the iron to molten iron. The electrodes in theory should start to work as anode , and cathode to precipitate iron while leaving the oxygen as a free radical to float away. This could be a way to reduce iron oxides without the need for carbon based fluxes. A sheilding gas like argon over the melt may help.
This was just an experiment, and was surprised how easy the iron sand actually melted with only 20 Amps. I have built a prototype arc furnace but haven't fully tested it yet.
I'm using AC, working on a 5 kVA 55 Volts 80 Ampère transformator
Nee, een grootschalige ijzersmelterij zit er voorlopig nog niet in denk ik ;). BTW, hoe hoog is jouw stroomrekening elke maand? Met dit soort experimenten zal die toch wel oplopen denk ik?
Dan moet ik ook een zwaardere leiding laten aanleggen. Ik heb nu 80 Ampère beschikbaar bij 240 Volts.
Ons verbruik ligt tussen de 1200 en 1500 kWh per maand. ongeveer NZ 300 ( 130 Euro's ). Een zaterdag middagje experimenteren verbruikt ongeveer 30 kWh.
This is really sad, I was hoping to see the end result - the glass or whatever that was produced.

@virgilius1979 Yes you are correct with the temperatures. The ironsand will be below 1084°C as the Cu electrodes don't melt.

how about lime and charcoal? and carbon electrodes? might make some calcium carbide.

what would happen if youy got zapped by 240?

Worst case: death. Or you could get a good zap and survive.
Simply, be carefull when experimenting with mains electricity.

Goeie dag! 80 Ampère is geen kattenpis!

Electrische verwarming en fornuis, oven en boiler. alhoewel gecontroleerd over de piek periode.
