Blast Furnace

[jeetendrag10acc2]

melt the chairs!!!!! melt the chairs!!!! melt the chairs!!!!! yaaaaaaaaayyyy!!!!

[shasta1112]

one question.. did you pour the molten aluminum into a plastic container?

[YTBYlover]

Fuel costed more then the end product.

[MrSttelnoj]

very cool! we'd never of thought of that at that age.

[vettefan73]

what was the "fuel" u used?

[EarlRausch]

Good Job guys, Keep the desire to discover alive !

Loved the use of duct tape, :)

[MrThahey]

next time try to use coke or lump charcoal instead of briquettes.

[hooplemott]

Give em a break! this is how stuff is discovered!

[43932]

Very nice 

[efexor666]

That fist! BRILLIANT!!!

[stambo2001]

totally awesome stuff guys. 

[Thetruthishere11]

weak.  can't melt cans.

[duskesko]

you guys did a nice job!

[suprninja]

Tooools

[duskesko]

@suprninja No, sir, they are the opposite of tools.

[YTBYlover]

youd have more luck melting the chairs

[zataflex]

Good job guys

[breakmonker]

awesome stuff

[edj66]

See that's the sort of thing kids ought to be doing!! Awesome job.

[100000000years]

does any one knows how to melt tungsten

[tTatmosT]

induction furnace will melt everything conductive the problem is finding the electrical power to run it...

[edj66]

Get a real hot fire.

[joltzkrieg]

not a blast furnace but still, same idea, good job

[joltzkrieg]

@joltzkrieg i take that comment back, it is a blast furnace, i didnt watch the entire video xD

[random90909090]

makes you wonder what happens if you put a small baby in there dont it

[Hellothere212121]

Looks like their aluminum started to burn at one point.

[darksideofthebrick13]

FRANZ FERDINAND ROCKS

[ivanov3000mltk]

Good job! Chosen song is nice too :) Hold on

[hazmat440]

nice job guys, too bad there is always people who use profanity when trying to express ones self with comments learn some vocab!!

[camochannel1]

very cool, good job guys.

[NickBlackDIN]

verry nicely done :) much metter then what most kids are up to now-a-days. XD

[madkanhaiya]

@NickBlackDIN u mean watching 18+ stuff on internet XD

[chena3]

good job guys

think hot

work hotter

[jaroslavpirkl]

fucking fist, put it in your ass...I'm not...

[codydean10]

it will get hotter if you break the charcosl up with a hammer

[contentlocked99]

i live by a railroad track, free coal owns lol

[BigDmaxwell0]

ahahaha u use same kind of shitty briquets i use to barbique with ahahaha....i hate being poor

[chaz706]

It's not so bad...

...and they still work!

[recpyro]

I just made a scale version furnace from coffee cans. Works like a charm!

[username2274317]

put vid plz

[JOCKATEO]

fuck great job and stupid in shorts lol

[Abovegroundminer]

Water and molten metal cause harm to body. bIG TIME!

[americafirst101]

Well I think it was a great job

Smart group there

I would like to see you use protective equipment while doing this stuff. Your legs for one thing, you guys had shorts on...not good...you should protect you self head to toe....Great job other than that...

[dudebot09]

You should use lump charcoal: it's cheaper, and more energy dense. Also, you dont really need a big exaust port, because at higher pressures, the material will heat much much faster.

[zachlr1]

What song is that?

[furiousharry]

read the info

[zachlr1]

Did you notice the "EDIT" tag? It wasn't there four months ago.

[noblenobster]

Great video. I have used it several times in class to great effect. Thanks.

[fredmentor]

Nice boys ;) Good video! *5

[tTatmosT]

thats not a blast furnace but its still good

[billygotgrove]

actually it is a blast furnace

Any furnace that uses a forced draft as they had is a blast furnace

[tTatmosT]

then every furnace is a blast furnace... they all use forced air...

[splint3048]

My gas fired furnace does not use forced air.

[tTatmosT]

it used forced gas, air is also a gas... so it's almost the same thing

[splint3048]

Mine does not use forced air, the fuel is forced at about 5 psi but there is no air pump. It is like a huge bunsen burner and it works very effectively. If designed correctly there is no need for forced air. You can see it in action in my videos.

[tTatmosT]

what I mean is that a blast furnafe isn't only something that uses forced air/gas to melt metal.

It doesn't have a pump forcing the gas but the gas is under pressure so it's forced out of the cannister...

[tTatmosT]

nice furnace by the way, a few degrees more and you could melt iron.

I'm going to try using pure (almost pure) oxigen to "feed" the fire so I can reach a higher temp and melt iron, I think I've reached about 1200ºC 1300ºC because it can melt copper pretty fast

[hellstudios]

THE VIDEO! IT DOEZ NOTHING BUT LOAD!

[justinjag101]

wuah, true that, i'll see if I can get that fixed

[dodgechevywheelies]

it got white hot and i think my granpa got burned by slage or something like that once

[ProfessorIgor]

you guys made a forge, not a blast furnace.. a blast furnace converts raw ore into a metal by a thermochemical process. The blast furnace is fed by several tuyeres blasting HOT air (1500c)into the hearth causing the coke to ignite and react with iron ore and limestone (flux) to create pig iron. Blast Furnaces operate at around 3000F

[justinjag101]

agreed, however, as we were young and blissfully unaware at the time, the term "Blast Furnace" just seemed to stick.

[ProfessorIgor]

you want a real treat.... pump pure oxygen into the "furnace" you guys greated.... the aluminum will actually burst into SUPER bright whitish blue flames kinda like magnesium. We would sometimes throw aluminum cans into the slag pots when I worked a co-op job at Great Lakes Steel... ahhh, the memories

[billygotgrove]

A forge is where iron is heated up to be FORGED hence the name forge. What they are doing is melting metal to cast it. But oh well changing the name doesn't change the function. By the way, I built one of these before. Just slightly different.

[starshock01]

nice job!

[sbennettyt]

I wanna know how the furnace was constructed!

Good job guys. Way cool.

[Mikl155]

hey, this is mike from the vid. the bottom was made with a pail with a kitchen soup pot pushed inside, we put in the copper air pipe before the concrete (much easier) we then poured in concrete (couldnt find fire clay) and the top was made with a similar pail and a coffee can with a hole in the top to keep the shape, we used a rolled up piece of laminate flooring to keep the shape of the chimeny (it burns out when first fired up) and thats it.

[Belmakar]

good job guys. btw if you switch to using lump charcoal instead of briquettes you'll get a few hundred extra degrees and less ash, even though you will have to burn more lump then briquettes in a given time period...

[mattrjim]

did you use a hairdryer, compresed air or propane???

[Kentboy05]

lol who was the one brave enough to bunch the molten medel

[sbennettyt]

are you serious? They made an impression of a fist in the sand and that was the mold.

Very cool I wanna try this.

[INSdivision6]

that was awesome!!!

[justinjag101]

haha, good thing i'm Canadian eh?

[bobby32123]

that is gay.

[Suckerbrot]

whzats the name of the song? ^^

[TheYouuTubeRipper]

Suckerbrot: The song is called "You Could Have It So Much Better" by Franz Ferdinand

I just wanted to know how these American blokes knew about it. It's British music and Americans aren't usually aware (or care) of what's beyond their own shore.

[Dk120000]

The name of the song is "The Fallen" by Franz Ferdinand and great work on your crucible style furnace

[TheYouuTubeRipper]

yeah, sorry I got it wrong. I was pissed when I posted my last message and I typed a whole lot of shit and then deleted some but I deleted the wrong bit (or rather, left in the wrong bit - the album name. It's a top song.

I'm pissed now but I think I got this one right.

I drink too much ;)

[Dk120000]

np im an American Bloke

[straker1999]

that was educational ... well done lads, i really enjoyed it.

[weaponsmith321]

great vid lads

[safuttias]

complimenti!

[boatandfireman]

sweet just like the one i made

[niel80]

Nice! I like it !...and the dipping bucket is made of what?...the center one?

[justinjag101]

man, I'm actually not sure, but I'm assuming that it's stainless steel (got it from Canadian Tire, $10)

[niel80]

OK :) thanx a lot for the info and again...congrats!

[gewehrmeister3777]

That blue flame is magnesium burning. Your furnace charge probably had some magnesium alloy in it.

[phillydude49]

The blue flame was probably the zinc layer burning, I've burned galvonized wire before. Just dont breathe the smoke.

[98209276]

that was so cool was the blue flame burning galvanised steel on the bucket im building mine with an induction coi?

[zernage]

Good work guys.

[jommy99]

Looks like good fun, nice bucket furnace. I enjoyed the video, and the tune in the background. The casting was interesting too!

[bgineat]

well built furnace! whats with the blue flame for a moment there comming out the top what was that from? but yea you really had air pumping nice in there. I built one years ago and used a ocillating fan to pump air but only it only does so much. yours did better. be careful good luck

[justinjag101]

Thanks for the comment, its good to hear that people are appreciating furnace construction! The blue flame was actually a glitch when we added a pipe (from a bathroom towel hanger? very lightweight) through the hole in the lid to be melted. I'm guessing it was a magnesium allow. And the intense pumping air... shopvac put on "blow", duct taped to the furnace. :)

[MofoKaye]

It's always nice to know people get as bored as I do :D
