There's a pretty awesome video where an African village smelted iron using traditional methods, basically the village elders recreating from memory what is otherwise a lost art... They use a termite mound as their clay source. The video is posted by Christopher Roy, titled "Smelting Iron In Africa (A DEMONSTRATION)".

Nice build. FYI, its a 'furnace'. A foundry is the whole set-up ( building, plant, etc). A Forge is for heating metal, so you can then shape it ( blacksmithing). If you are working with Aluminium, you want the temp round 700c. As I understand it, too much heat will leave you with a porous casting. 👍

If you want to weld that stainless tubing without a purge, and have less interference in your weld structure/appearance, keep your welding downhillish as you go around the tubing (same with welding any gaps for stainless). That is one hot stove (furnace) 🙂👍 Pretty cool 😏

Your furnace is brilliant!!!! Once you get some appropriate furnace tongs to grip the crucible the pouring will be much safer. You can use your lifting tong then switch to a pouring tong if you like. I was so impressed with the termite mound as a furnace lining. We used gannister and fire clays/bricks together with high end ceramics etc. I can assure you your lining stood up as well as anything we did. You can do patch repairs but I expect you aren't going to be pushing it hard. The use of the k type thermocouple was great. You can also get cheaper one shot dipping thermocouples but maybe that would cost more in the long run. Then theres IR but do you really need to go further. When you consider safety gear a good thick leather metal workers apron is a real benefit and although the safety officer might complain wear your boots slip shod so you can flip them off instantly if metal gets in. Seen many a leg saved from cremation that way. Shedding molten metal is better than holding it in your clothing. Maybe you have looked on line for foundry supply companies for an idea of all the safety wear. I would go with heavy leather gauntlets, leather apron, leather boot covers, leather boots, full face visor and fresh air flow. Out of touch with the market and only really knew one tooling company in Australia. Can I say water is the enemy in casting. On top of metal okay. Under metal run. That vlog is the best thing I have seen in ages. Learnt so much good stuff watching you. More power to your elbow. Many thanks. Please keep on with your brilliant work. Its inspiring.

For melting aluminum, pearlite and vermiculite will work fine, but at higher temperatures, like for melting bronze and iron, those materials act like a flux and it lowers the melting point of the material around it. In a way it sort of creates a type of glass that weakens everything around it. Clay and sand mixtures work a lot better for high temperatures. Basically the higher the alumina content of the clay, the better. It takes a lot of trial and error to find a good clay/sand mixture that works well. If you want to skip all that, one of the easiest and best performing ways to make a furnace is to just get a metal cylinder, line the inside with 3-6 inches of Kaowool then coat it with a layer of castable hot face like ITC 100. That stuff has a melting point of 2482°C and is used to reflect the heat of your furnace back into your crucible.

ITC 100HT is way too expensive to use on its own, but this is very nearly correct. One should use a stabilizer on the refractory insulator to protect it from shock and slag, coat the stabilized refractory in satanite refractory cement to give it rigidity, and then coat the satanite in the 100HT. That stuff is like $75USD a pint and a pint is at least enough for 2-3 projects this size. I don't trust 100HT for structural support and will use a SS tray anywhere that it might get hit by slag. The 100HT is primarily desirable for heat up time reduction and heat retention. It reflects IR radiation when it gets to a high temp and increases in efficiency of reflection the hotter it gets up to its thermal limitations. I'm about to build a small propane forge with this method and an Aussie style adjustable self aspirated burner. If I'm wrong about anything I've learned from trusted sources in this, I'll edit the comment with what failed and how. TL;DR: Satanite is $1/lb, 100HT is $40/lb. Use stabilizer on kaowool or carbon felt. Use satanite to give it physical durability and add a small additional insulation layer. Use 100HT only for its IR reflective properties so that it pays for itself after 200lbs of fuel are used.
@Brokentwobutton
@Brokentwobutton Жыл бұрын
​@@LittleAussieRocketscheck my comment above. Kaowool or similar ceramic alumina refractory fiber insulation MUST be treated with a stabilizer to be safe to breath around and prevent damage to your insulation. It needs to be further protected with a cement. ITQ 100HT is incredibly expensive and should only be used for IR reflectivity because of that. Manufacturer instructions say the specific coating thickness for efficacy. I've heard it reduces fuel costs by about 20%. I don't know if time and twig savings make $75USD worth it, but using a purchased fuel source would justify it.

My great grandparents lived in a bush camp on North Straddie, and they made their wood-fired oven out of termite cement. I have found perlite doesn't do so well mixed in - as it breaks down into dust with only a fraction of the original volume. Vermiculite falls apart as well, but doesn't seem to completely disintegrate as much. (On the other hand, for hydroponics I prefer perlite to vermiculite due to the open space). Once again, informative, entertaining and impressive.

the problem with wood is the residual 10% moisture will cool your foundry when adding new fuel before heating it back up. i read somewhere roughly, 1/3rd burn time it sucks heat out of the foundry, 1/3rd it burns of volatiles and the last 1/3rd its a pure coal fire. The stove design continuous feed solves the biggest flaw of my setup below, in my forced air brick foundry i could melt 4 kg aluminium in 40 minutes from cold start, but when i tried 1kg copper it took over 5 hours burning through 3 wheelbarrows of woodchips I mean the people with the syphon nozzle sometimes use an air drier in their hose

I considered building a furnace with the combustion coming from a wood gasifier (fema or imbert design), but without the syngas cleaning and condensation part. The problem was in the suction to exhaust the gas in the burning chamber, fans would not work in the medium-long term in direct contact with the gas due to tar impregnation on the blades, it would have to be with a venturi effect and very strong to work (probably compressed air). Its design based directly on a Rocket-Stove is more cost-effective to do, even though the burning process has a lot of moisture from the wood/biomass due to the lack of a pre-drying chamber, the cold air doesn't help either.

I really like this design. What a cool option over expensive gas. Some time ago I did a deep dive into cob ovens for pizza and baking. There are a range very specific ratio mixes of clay, sand and cellulose (straw, grass etc). The old timers wound that termite mounds had these ratios perfect. No need for sifting sand for grain sizes, no need to experiment with your particular local clay to soil ratio, and no need to chop up straw and mix it in. As for the straw, it's not really possible as a DIY to get it chopped small enough and mix it evenly. The termites have the cellulose particles in such small sizes and mixed perfectly. The Clay to sand/dirt ratio is important as pure clay will shrink too much and not handle the heat cycles of uneven heats causing huge cracks. The cellulose particles will burn out leaving tiny air pockets which will insulate.

Great Content my friend! I'm will make an above ground pool(8500gal) heater. Trying to figure out the best way to transfer the heat from wood to the pool. My plan is to fire a water filled 55gal steel drum with protruding angle iron nubs inside and out on bottom with a forced air rocket stove. Plan to use 2, 3 or 4 - 2.5ft length 3/4" copper pipe radiators coupled to a pvc manifold both sides of the drum , in the heated water drum to transfer the heat to the pool - using 1 1/4" pvc pipe with pool pump. High volume is key here, aprox 3000gph, looking to heat the output water to about 100f max or less. Would it be better to heat the copper pipe in a direct flame? I did play around with direct fire heating with my smokeless firepit but the cold coil copper extracted way to much heat from the fire causing terrible burn quality. Thanks,

At least with forges, typically you'd do the lining and a light fire, look at the cracks and then just put a thin slurry over them which will generally hold up ok. Ultimately though, refractory material is a 'wear item' which is getting replaced eventually and don't get too attached to it being there forever. In terms of the fuel, I think you're probably hitting the peak with the timber and nuts, if you throw some charcoal in there I can easily see that getting well into the 11-1200C. Through summer you might want to chuck a mesh spark arrester on the top so it doesn't set the countryside on fire as much :) Oh yeah- you can make crucible tongs easily enough with a rimmed crucible, for the larger types that don't, you'll want what's called a cradle, which is essentially a round loop and a clamp which comes in over the top to stop it tumbling out when turning sideways

Would it be possible to take the exhaust heat and run it through a heat exchanger to heat up the input air?

The temp inside the furnace may have been higher than the burn tube. The burn tube is closer to cold intake air and the furnace is able to retain and gain more heat as it is lined with refractory. Nice to see your journey. I must restart my own.

If he had insulated the combustion tube, the temperature sensor would be in the correct position. Everything in the forge can be heated to the maximum temperature of the flame. The flame temperature at the entrance would therefore represent a maximum temperature.

Great point! I have some gray cast-iron that melts at around 1200'C That would be a test for it.

Where did you learn how to weld?
@LittleAussieRockets
@LittleAussieRockets Жыл бұрын
I always wanted a job where I could weld but because of my lack of experience and no one would give me any work so I enrolled myself in a local TAFE and started working through the different welding modules. Stick welding, mig welding and Tig. The experience I learned there opened the doors for me to get a job where I could weld every day, and that's really the key is practicing everyday. I'm very blessed to have worked with some very skilled welders who showed me a lot of tricks and techniques.

I'm going to have to do an in-depth video where I run all different fuels through it. I intended on doing that with this video. I just ran out of time.

wait so when you're welding that pipe you're not using anything as a filler? just fusing the stainless steel to itself?

Yes, that's correct. That's pretty standard practice for low pressure applications, particularly around the food grade industry, which is what I do most of my work in.

Vermiculite and perlite are prone to hold moisture. Best to dry out before this type of application
