dude i don't get its its not even melting anything l m a o

[jpchapboy]

needs a lid

[tTatmosT]

what kind of charcoal do you use for this furnace?

[alexplace2001]

Its common vegetable coal.

[tTatmosT]

and u can melt iron with your furnace or only aluminum?

[Whackvids]

This is not a blast furnace OR a forge. This is a regular melting furnace.

Blast furnaces smelt ore. Forges heat metal(usually steel) to be worked.

[alexplace2001]

I used this name, because in the Gingery  books, its refered as a Blast Furnace. I think you are right a blast furnace needs ores and fluxes.

[ProfessorIgor]

this is a forge, not a blast furnace.

[mercanaries3]

its not even melting

[bsbtervuren]

do they use iron oxide in blast furnaces? ? ?? ?

Cool. I was thinking on just making a hole in the ground for now. What do you use as a blower? A simple vac? I have one I got out of an upright that blows pretty hard but I will be using a home made bellows that may take a little longer but what the hell. How many times do you have to refill the charcoal (if at all) for that size crucible? Looks like a 16 oz. propane bottle there. Does it make smoke when its lit or smell like smoke at all?

[alexplace2001]

Hi

I use a vacum as a blower. For air regulation, I made a hole in the hose that connects the vacum to the furnace. Then I added some tape to get the required air volume.

In a normal melt I refill de furnace once.

When the charcoal begins to burn, it makes some smoke. When its hot and running, it burns nice without smoke.

What is that made of? Portland cement or refractory cement? Is that burner right in the middle or is it just an airtube with charcoal

? If so, how do you rate its efficency?

[alexplace2001]

Its made of comon cement and yello sand. Its an air tube with charcoal. I don't rate the efficency. If it melts aluminium its ok.

[trytops007]

invest into a lid it will make the melts quicker , keeps in more heat which equals in less cost in fuel
