I want to melt 500-700 kg iron to make casting. Which is cheapest method.?
Answer:
It has been a long time since I heard about this, but a guy in art class at college at college did this using a large amount of wood.
Plug in your electric furnace to your neighbors outlet.
u need to have a huge machine with fuel or gas in it n fire holes in it,same like a kicthen stove,big machine huge stoves with lots of fuel or gas , can melt iron or go for huge heaters.
Short answer, you can't. You are going to have to contract the work out.
A bronze foundry might be easier to find.
take it to the volcano site
the easiest way to melt it is putting it into a furnace.
I've heard of electric arch furnace which melts the iron by the heat created when electricity jumps like in electric arched welding. i don't know where to find one but since this is used in industrial scale i guess its the cheapest.
for a DIY casting i guess a gas (acetylene ) torch welding can do the job. but since your talking about 500-700kg you'll have to break it into small pieces first before you can shape it into your mold.
how cost the only factor and not time? you can follow Mao's idea of melting it in a bonfire.
in real industry i think thst 500kg is nothing
its too less
so a small furnace can be selected but it cant done in home
there wil;l be huge powre require for induction furnace
A furnace capable of handling a melt that large is not a
'do it yourself` project.
You will have to get your mold to a local foundry.
They may well have reservations about a pour that large into an amateur built mold. (It IS dangerous you know.)
Your uncertainty, (40%), about the size of the pour is a sign that you need help.
