DIY Iron Furnace Build

I made a small furnace for casting iron and stainless steel.
It uses the same burner as my aluminum furnace but takes about 2 hours to heat up( a .75GPH nozzle is in the mail). If you wanted to save fuel simply coating ceramic blanket in santanite or Itc-100 might be better. I wanted something more robust, the refractory is very heavy and rated to 3000F. I should be able to push it a bit but the crucible won't quite cut it. I'll likely need one that's rated higher and can be capped and flooded with argon.
*********** CRUCIBLE - Purchased on EBAY -A10 Clay graphite
Fuel- Start on propane, than switch to diesel
I'm pretty happy with it and some of my castings have come out nice(video on that later) but they do rust quick unpainted.
If you have any suggestions let me know.
I got the Cast-O-lite 30 off ebay + some mizzou plus for plinths and the 2600F ceramic blanket
I made all the foundry tools with hardware store steel
The 10 gallon barrel was free and stays touchable even when the pour is molten!
This is really dangerous, the molten iron can go right through just about anything. Start with aluminum before going up to iron. The fumes are bad, the heat will melt flesh, the fuel tank could explode the crucible could rupture, the pour could hit water. You really need to be careful
Consider supporting me and my projects on patreon! / bennbuilds
**Note about my shoes: They are made of leather, plus they can be kicked off super quick, plus I tested them by pouring some metal on them and it was not a big deal at all, so I wouldn't even need to.
Its a small furnace in an open space that's really easy to run away from in the case of an accident such as a crucible rupture or spill, and no skin is exposed so I'm pretty safe from splatters.
Also, all the clothing can be removed really quickly, witch matters most to me. Its surprisingly hard to get metal to pool up and burn through clothing, especially when you can shake around. And if it does just pull the clothing off as you run away.
This is not a professional foundry where you can get trapped and there are thousands of pounds of molten metal around you. Danger scales, like everything else. Incandescent light bulbs get hotter than this, yes they burn down houses but you don't wear a fire suit in your kitchen.

Great work! A few tips though, you're losing a lot of heat through those gaps in the lid. Also, if you're using a ceramic mold that you plan on breaking, I'd add some sand and bottle glass to the metal to help remove slag from the mixture. Other than those things, there isn't much else to say. Be safe, and have fun!

@aubreyaub 8 лет назад

A furnace, using wool and coatings like ITC-100 are QUICK cookers.,and are better for the occasional cook up. The fire has only the crucible and contents to heat up. A furnace made using a "castable" is better for LOTS of cooking ,over an extended period. It takes a LOT of Energy (Fuel), just to heat the furnace up, before we even start to heat up the crucible and contents. and edit. Cast iron weights, are great cast iron, soft gray, and can be found cheap.

@echoseven8580 9 лет назад

if you are interested in starting a blacksmithing career or just blacksmithing as a hobby then I suggest making a forge which there are several tutorials on how to do very cheap, get a hammer some fire proof gloves good goggles and some steel and dig a hole in the ground with a flat bottom then melt the steel and pour it into the hole if the hole was dug correctly and flat enough you should have a nice flat surface on which to start beating some iron with.

@polishfoundry 8 лет назад

if you plan on going with an o2 boost please go with at least 3200 preferably 3400 deg f refractory. also make sure your burner is all brass and it stainless. the flame from an o2 boosted diesel burner can hit 4500 plus f. if you do use it try and wait till the end to quickly ramp up to pour.

@dukeofalltrades4470 8 лет назад

i think the reason youre getting dross in your casts might be that youre not fluxing your casting material.

@apocalypsegaming6083 7 лет назад

Okay so I've made a furnace I suppose and its made out of brick, clay, and rocks and wood burning. I use a hair dryer to heat things up. Anyway so my back yard volcano has recently demonstrated that it can liquefy high carbon steel without many issues. I don't know whether to be proud or concerned.

@ericf.wolcott4716 5 лет назад

I seem to remember from shop class that our crucible 'pouring' handles had a simple 't' welded to the end for better control. Helped apply torque and control the speed of the pour. I could not see if your handle had such, but I figure that 'more control' equals 'better pour' and 'more safety'.

@alastairmacintosh7149 7 лет назад

I knew a guy who wore shoes in the foundry. He was warned not to by the moulders, who wore special quick release boots. One day when he was skimming a moulder's ladle during casting, a newly cast box burst and the metal ran down his leg and into his shoe. He was very badly burned. At the very least, wear ankle boots and thick cotton trousers that cover the top of the boots. Take care.

@bradyrose 9 лет назад

most impressive casting video I've seen to date.

@davidmcleod9996 6 лет назад

With iron it's called slag not dross just so that you get your terminology correct for future videos. I know because I work in an iron foundry. And we add copper and nickel in set amounts to our alloy to make ductile iron. Just a suggestion.

@AnonymousHedge 8 лет назад

You should add some scrap aluminum to the iron while it's molten. It will lower the slag and dross content, lower the carbon content and melting point, deoxidize the iron and also harden and strengthen it

@sebast007 6 лет назад

It must have been said before, but you are working dangerously. Don't take it the wrong way, but you should have proper protective equipment and not just tiny shoes (for ex.)... I work in an iron ore plant and some people burned themselves pretty badly WITH proper protective equipment. Other than that, great video. You have a cool furnace!

@CoolKoon 8 лет назад

Just a tip for gauging the amount of iron you'll need for the pour: 1) Get a container that's big enough to hold your pattern 2) Pour some water in it (enough so that the pattern will be covered completely when submerged) 3) Mark the water level inside the container 4) Drop the pattern in it. When necessary, hold it (completely) underwater using tongs, a poker etc. 5) With the pattern still underwater, start pouring the water from the container into a measuring cup until your hit the mark you've created earlier 6) Now you have the volume of your desired object. Combined with the density of cast iron (density x volume) you get the weight of iron you need to melt in order for the cast to be successful (applying a slightly bit more never hurts though :P ) Saves a lot of headache and remelting ;)

@aubreyaub 8 лет назад

+CoolKoon or just weigh the pattern. density of wood and density of metal, bit of maths 'n your done. Quite a bit more for runners, spout, dross losses, so on. Takes bugger all, to heat up 3kg instead of 1kg. Now watch someone else, tell us another way to do it. More than one way to suck this egg, Hey!

@CoolKoon 8 лет назад

+aubreyaub Yeah, it's the easiest option for common homogeneous materials. However the density of engineered and natural wood is not the same BY FAR (not even the density of hardwood and softwood). AFAICT the pattern he used was made from LVL. So he might be able to look up its density somewhere or might not. If he can, then yeah, weighting the pattern then converting that to the weight of equal iron is the best option. But with inhomogeneous materials (e.g. glass or carbon fiber reinforced epoxy, concrete, items made from two different materials e.g. a hammer with a wooden handle etc.) whose density is not known my method might be pretty much the only option.

@CoolKoon 8 лет назад

First of all had you seen the video you'd know that they were pouring the iron directly into the open mold, so there's no need to account for sprouts, runners etc. Second of course you need to melt more material, but with knowing the volume/weight of your material, you know how much material must absolutely be left after you account for slag (which allows you to adjust the charge accordingly). BTW bronze is a different story, because it doesn't produce (well, call for) as much slag as iron does.

@gusbisbal9803 7 лет назад

Dude, when you picked up the oxygen lance, that is when I thought..."Oh your not, seriously?!" but well done on doing it. With a diesel furnace your limited not by fuel but by oxidant levels. I have a 0.8GPH head and I its almost too big. Well done on this. Don't worry about the saftey nanny comments. The only thing your doing that I wouldn't advise is hitting the hot crucible to get the Dross out. It can get soft when hot and knocking it can introduce some stress fractures. Other than that well done on all of this you crazy bastard :-) (On the Oxygen, well done on keeing the bottle WAY back from the fire, making sure that hose doesn't melt is probably your biggest safety risk, or should I say out of all you safety risks, your biggest :-)

@BenNBuilds 7 лет назад

The crucible was full of aerated carbon/ glass coating from some of the scrap metal I melted and would not come out or melt. There was still a lot left in there after that.

@gusbisbal9803 7 лет назад

I used to be a industrial glass chemist. What you need is some flux. Some high exo thermic flux pour it on in a healthy manner and letting cook a little. It will help melt away the silicates and will lower their melting temperature. Its a pot cleaner basically. Keep up the insanity :-)

@sandrammer 9 лет назад

Howdy, You don't need to add carbon if you use a clay graphite crucible because the melt leaches out the carbon from the crucible. You shouldn't use a clay graphite crucible but need to use a silicon carbide crucible. Both crucibles will handle the heat but you will make your iron or steel useless if they absorb too much carbon. Even if no carbon is absorbed from the environment, cast iron, straight out of the mold, is as brittle as glass because the carbon in the melt is still in string form. Heat treating the cast iron allows the carbon to change into nodules and becoming Wrought Iron. A material much more suited for use as a cooking tool or machine part. Question; was the lining of your furnace rammed with Cast-o-lite 30 plus?

@sandrammer 9 лет назад

Just so you know, I was a Navy Molder (foundryman) for 20 years.

@sandrammer 9 лет назад

If you have any questions about Foundry techniques or Foundry related work...my email is; sandrammer@aol.com I'll be happy to answer your questions.

@sandrammer 9 лет назад

sandrammer One more thing...I see that the pedestal that your crucible is sitting on stays in contact with the crucible when you take it out and pour the metal. The solution to that problem is to put a couple of pages of paper under the crucible before you start the heat and when the melt is heating up, the paper turns into carbon and makes a barrier that the pedestal won't stick to or you can make a refractory wash and paint the top of the pedestal again making a barrier that the crucible won't stick to. Have fun!

@BenNBuilds 9 лет назад

sandrammer Thanks for all the helpfull tips! I did that a few times, even using cardboard and 1/4 inch wood; it still stuck. W When this crucible burns through (my 2nd so far) I'll definitely go for a silicon carbide one. The furnace was just cast-O-lite 30 for a while than I lined it with ITC-100 after a little while

@jonathonwood4088 8 лет назад

You should have a flow of oxygen, replace the blower you have with it, or add in the O2 into the blower's pipe. pure O2 will make it incredibly hot, youd be making a blast furnace, that's how cast iron and steel is actually made

@pjemrey6676 5 лет назад

I'm two years late, but that isn't a good idea. Propane with pure oxygen heats up to over 5000°F, 2000 degrees more than the maximum heat rating for the Kast-O-Lite 30. First it would destroy the crucible, then it would melt the actual furnace.

Nice! The hardest part with a fired furnace is simply to get up to temperature (although, blowing in oxygen solved that problem). With an electric one (like I have) it's easy to get up to temperature - but the hard part is to not have the heating elements melting.

@ChristopherJones16 3 года назад

You put a paper towel around a cylinder object for your lid.. it looked like duct tape rolls.. Did you use that as a mold/form for the lid's hole and remove it once the refractory cement cured, or did you keep it there? I noticed you were placing the lid on your foundry very carefully as if you were lining up an extruded part of the lid to insert into the center of the foundry opening.. Am I assuming correctly that you kept that roll of tape object in your lid as an extrusion so the lid can "lock in" into the foundry and seal the gaps? If so, that was a great idea that I havent seen anyone else use in their foundry-making videos. A big problem guys are having is they cant get their lid refractory perfectly level with the foundry's refractory top walls to create a great seal... The extruded refractory area in the lid would help combat leakage.

@BenNBuilds 7 лет назад

The crucible tool works pretty well, haven't had issues with it yet. It deforms slightly when lifted so it holds pretty good through the pour, it even holds it upside-down. When pouring it never needs to go past the center of gravity either, so its not going to fall out when full of metal as long as I pour slow enough. The crucible was full of aerated carbon/ glass coating from some of the scrap metal I melted and would not come out or melt. There was still a lot left in there after that.

Worked in a foundry in Bham. In order to pull impurities out we used limestone, the same stuff used on driveways. I found that when molten steel came in contact with water it would explode like tnt, when coming in contact with concrete the concrete would burn leaving large holes. We had to use steel toe boots with steel flaps covering the strings. Welders goggles to prevent permanent white spots in our vision. Our pour temps were in excess of 2500 degrees faren. This is something that you should work up to starting with alum, then copper and brass. Please be careful and be prepared for the worst !

@kalleklp7291 7 лет назад

Looks good, but I see there is a problem about getting it hot enough for melting steel/iron. You could try and make a waste oil burner for it. With the right dimensions, I guarantee it will get hot enough to melt steel in. Pleasant side effect...it's much cheaper than propane. Also, you should get some flux material, or the metal will oxidize very quick. That's especially true on cast iron, which is a bitch when it comes to air. However, for soft materials like Aluminium and Copper, your setup is quite sufficient.

of course... oil was used in plenty of smelting ops. springfield arsenal used oil muffles to forge out 1903 rifles until the 20s (when they switched to gas furnaces). the real "secret" is preheating the feed air for the burner. that saves plenty of BTUs otherwise wasted, increases efficiency of atomization, and efficiency of burn. that set-up in the vid just needs pre-heating of the combustion intake, and he'd get a hot enough pour. look at cupola smelter designs, the tuyers (sp?) that feed combustion air to the melt get a few stages of pre-heating. granted a cupola uses coal usually, but they have poured iron off charcoal as well, which has far lower heat density than diesel. if you use a centrifugal "trash pump" volute and impeller blower, then just hinge an intake tube of stainless at the blower inlet, so it overhangs the furnace exhaust in the lid. if you use a shop-vac type set-up (where the motor is actually exposed to the feed air), then you place a loop over the lid AFTER the blower. the only caveat is to make sure you get CLEAN air (not flue gasses), and to make sure your volume is high enough to run just a little lean (surplus oxygen). you could also go exotic, and run nitrous oxide (twice as much oxygen per unit volume as air), or even oxygen, or even spray some hydrogen peroxide (not the first aid variety, lol) to increase temps, but that's a bit much for a home rig. surplus blower volume and pre-heating feed air should get you hot enough for a good pour. bear in mind, REAL iron (not his steel pour) runs about 500 degrees hotter still, so requires even more effort to get up to pour temps.
