- Melting Iron with Propane in my Homemade Furnace / How to melt Iron at Home
Deutsche Version: • EISEN selber schmelzen...
In this video, I bring my furnace to the limit. Cast iron is quite a challenge and I have to heat the oven for almost 40 minutes. Unlike molten copper, you can not look at the iron anymore. Without darkened safety goggles you only see a blindingly bright light. Nevertheless, the molten iron can be poured very well, since it is very runny.
I enjoy most casting videos. This one is no different. What I like about smaller youtubers is the lack of high end professional grade tools. Small details that just solidifies too me, that I as a hobbyist, dont need to spend 10k on just tools and another 5k on a furnace. Keep doing what you do. Got a new sub in me.
2:53 for a split second there, your brain told you "Just pick it up ;) ;) ;)"
Great video! Thank you for sharing.
I don't think people appreciate just how loud those furnaces can be (but it does sound kind of cool)! This video sure does give a good example though.
Pretty cool can you amagen flying over in a plan and seeing the light from the liquid metal
Its so beautiful color
Hallo! Very impresssive! I had the same problem with cold gas bottles. My solution was a shopmade 50mBar propane burner.
Great stuff now you can mould anything you like
هل يمكن ان تعلمني كيف صنعت الفرن وما نوع البوتقة لو سمحت
Scary! Amazing
Very enjoyable
Way to go.👍👍👌👌
this was amazing, first time i have seen a cast iron melt cheers man you fucking nailed it
Sir, what material have you used to make the furnace?
Based austrian guy. Greetings from Albania
Love the billa bucket
Hello sir, great job with 😁👍
I'm actually making a furnace for wootz making
What kind of crucible did you used please?
I have been thinking about forging some reasonably high purity iron, it is fairly difficult to find any that is in reasonabley sized chunks. I might end up melting some wrought iron with a little soda lime glass and borax to remove most of the slag so I can forge the resulting ingot into nearly pure iron bars.
Pure Irons No Good ! Anyway !
Can you use any chemical to melting iron?
I wanted to see it done
I want to melt iron to it well help me
Sir i forget 🤔how much Gas consumed the furnace for 1kg of cast iron and How much time to take melt please tell me 🤔
Have you ever done melting magnitite sand that you can extract from the beach
No, but making iron from magnetite might be a future video.
Из чего у тебя тигель?
All those pretty colours at 5:55 :O
Its uv light or infrared
@@LuigiCotocea Actually, its just a large amount of radiation in the visible spectrum caused by black body radiation, otherwise you wouldn't be able to see it. Inevitably, there is also radiation of higher energy (UV) and lower energy (Infrared), but this is not visible.
1)hello. How much silicon is there in the iron used for doors and windows?
2)Is it possible to melt iron and copper together?
1) I don´t know exactly how much Si is in them, but if it is cast iron it should be ~3-4%
2) Yes you can melt copper and iron together, it creats a brittle alloy that tends to rust very fast. I´ve actually filmed a video about such an alloy, but haven't had the time to edit it.
@@SomeAustrianGuy ok. my oven is electric and can reach a maximum of 1250 ° C 1300 ° C how to melt a small part of iron in copper? is there a way?
@@lelearmi6186 mix them together
Can you please tell me what is slag actually and how its formed?
Slag is mostly a mixture of metal oxides. Most metals react with oxygen when they are hot and the resulting oxides are lighter than the liquid metal, which is why the slag collects on top. The slag can also contain impurities from the crucible.
what is the mold itself that you poured iron in it is made out of?
probably graphite
See that purple glow that the furnace and crucible had? That's the camera picking up UV!
is it hard to make weights out of melted iron? idk im probably just crazy. my friends called me crazy when i told them my idea.
If you can melt iron, making weights isn´t too hard. It depends on how accurate you want the weight to be. You need to make a sand mold with casting sand made for iron casting (this sand contains coal dust). If you want to make very accurate weights, that might be a problem.
How long did the iron take to melt and how much gas did you use?
Around 40 min. I´m not sure about the gas, something like 3 kg
SomeAustrianGuy thanks for the info 👍
Is it technically possibile to make cast iron casts with green sand molds?
It should be possible, but I´ve heard you need to add a bit of coaldust
@@SomeAustrianGuy Nice, so seems it is possible at home to make something useful in cast iron :) . Good job. 👍
No, I work in a steel foundry, green sand is ok for it. For iron you need to use some adding material only if you want specific solidification and specific mechanical properties with known iron composition. If you just want to cast something, for the beginning try with simple green sand but be careful of water, it's really important.
Do you know what regulations there are for using furnaces? Where can I use them by law? Can I use them at an empty park/ empty baseball field, at home??? @SomeAustrianGuy
Sorry I can only tell you about the law in austria, here you can use them on your property.
What materials used for making furnace (foundry)? Clay? Ceramic fiber? And hole jet gas dismeter? Thanks
The furnace is made out of firebricks, you can get them for different temperatures. I used bricks rated for 1430°C. The bricks are coated with refractory mortar. The hole is 7,5 cm in diameter.
@@SomeAustrianGuy thanks you very much! Regards from Argentina!!
@@SomeAustrianGuy 7,5 cm? No wonder it roars! ;-)
Have you ever tried to blow oxygen through cast iron to make it into steel
How long does it takes to cool down?
3-4 hours
Man that thing is glowing.
I wonder if it’s radiating any uv .
It's definitely radiating UV, thats why I need to wear welding goggles. I´m planning to go even higher with the temperature, my next goal is to cast ferrotitanium.
Thanks for sharing.... -some American guy- lol
Rare explaination video
Did you need to use a flux?
I think that i've used a bit of glass from a beer bottle.
Iron? But what for?
So when you melted the Cast iron, did it stay cast iron? or did you inadvertently make steel?
Yes, it was still cast iron. I would need to blow some oxygen into the liquid cast iron to make steel.
@@SomeAustrianGuy how would you go about doing that?
Edit: thank you for responding!
@@silveraxeofvalkenheim5350 I´ve never tried it, but I would use a refractory tube made of alumina and connect that to an oxygen tank. You could then blow oxygen on the liquid iron and burn away some of the dissolved carbon. This process would be extremely dangerous, because the reaction of liquid iron with o2 is very violent. Molten iron would probably be thrown everywhere.
@@SomeAustrianGuy Ok, because I was thinking of buying home radiators and turning them into steel, i've never done anything with molten metal but if its that dangerous then I dont think I will try anything. Thank you for responding in such quick time!
@@silveraxeofvalkenheim5350 Why would you want to Turn home Radiators into ! Steel !?? For !
Hi, what is the material of your crucible ?
It's a clay graphite crucible
Thank you. Is a homemade crucible or not ?
Just a thing, please, use better protections ! Your gloves are to thin, your shoes don't protect anything and your apron is very light for iron.
The crucible isn´t homemade, I got it from eBay. You are right about my equipment, I´m currently looking into aluminized clothing.
@@SomeAustrianGuy Better is asbestos or similar one. And no jewelry and synthetic shirts
Can we use this type of furnace for nickel melting
Melting nickel should be possible. You may want to inject some pure oxygen into the burner to raise the flame temperature.
@@SomeAustrianGuy i am planning to make raney nickel (aluminium+nickel) any suggestions you wanna give !
Could use a liqoud torch might be better
How long did it take to melt iron this way?
30-40min
You give oxygen with fire tell me
I'm blowing air into the furnace, but I'm not using pure oxygen.
Just you use gas only to meld iron
tungsten Melting point 3200° iron melting point 1500 °
Why its emmiting uv tho? I know its got! But its because it is hot!
Hot objects emit electromagnetic radiation, the wavelength gets shorter with increasing temperature. At 1400°C you get some uv mixed into the spectrum. If you are interested, look up "Black-body radiation".
steel can be melted in this furnace???
it always depend on what steel, but most of them yeah, mainly high carbon steel. only takes more time and gas
@@caiodollis6159i saw this on this channel how steel melts. at first it uses pure propane with air and after 20 minutes it enriches with oxygen. ruclips.net/video/x19jmuJ6hys/видео.htmlsi=IXHCwpSfwBKuVw0x
Hi sir namaste 🙏
Sir i am making my own diy projects working At my home but here is the problem sir 😔
Sir i want some parts for my project works but it was very expensive for my budget 😔 so I want to desided to make own melting furnace for my require materials like Zink, aluminium, brass, bronze,and copper these are easy to melt but I want some cast iron parts also sir please give me any tips or suggestions to building a Gas furnace please....
Sir please don't forget my request 🤗
I am waiting for your support 🤝
My greeting from iraq
High temperature tungsten melting no malt tungsten
Good watch YouTub
It is not a pure iron.
I want to see.... you melt pure iron.
This video is so dark so do a bright video please comment me
MELT A COIN IF YOU CAN REACH 1,984 DEGREES
Cristian is real ☦️❤😊
Переведи на русский пожалуйста
Так с расплавленным металлом работать нельзя! Хотя бы надо элементарную оснастку иметь и средства защиты. 1500 градусов по Цельсию - это весьма опасно!
