The design is wonderful. I learned a few new materials. Great use of electricity; I was going to run 240v but I think 2x 120v is smarter.
Please consider using proper tools and avoid setting crucibles on concrete; it could explode! I like your design the most from what I've seen and will emulate it with a much larger build!
Thank you!
I learned a lot from watching this. Thank you for the video.
Thank you!!
What a pleasure to watch. Love that your son came in to help. Mine use to help all the time but now video games rule his free time lol. Going to make one like yours. Thanks a bunch for sharing.
Thanks for the comment!
My son also went to play video games right after this. I guess all kids are the same...
I would love to see the can crusher you built!
A very tidy, high-quality job.
Thank you!!
That brick will damage your lungs if you dont wear a mask that can filter it, especially when cutting it on a power saw.
Thank you!
Agree about the bricks and the fire wool also. They contains silicates which once inside the lung, cannot escape leading to a lung condition called silicosis. ALWAYS wear a respirator when working with silicates. Fantastic build! 👍
@@7chome_seisakusyo is it a distribution strip
Beautiful job! Thank you! But be careful when taking the crucible out of furnace whilst it's plugged - you may be electrocuted from the spiral through the tongs
Oh! I thought I had turned it off. Thank you!
Very nice and to the point build. Thought it was soso till you placed blanket around the brick❤.
The last blanket could be regular house insalation to save money. Really nice job!!
Thank you!!
If I am not mistaken, the hand mixed heat resistant cement is called refractory. Great build! I thought when you hand made the lid / top and matching plug, it had to be initially fired (no metal to melt), then it was ready for use with metal. Did you make the crucible too? Thank you 🤓
Thanks for the comment!
The cement I used is fireproof. Quenching is not necessary, but I did it just in case.
I didn't add reinforcing steel bars to the lid I made in the video, so it cracked after a few uses.
So I rebuilt it after this with reinforcing steel bars.
The crucible was bought from amazon.
Please check out my other videos!
@@7chome_seisakusyo very welcome! Thank you for all the great answers! Domo arigato
Please can you explain the wiring. I understand the coppet electrodes, kathaline wire, but not the rest of the connections
Thank you very. I was so amazed to watch your video. Are you connecting to a power outlet or to generator
Thanks for the comment!
I just have two 600W kanthal wires connected directly to the outlet in parallel.
thank you for your video
Thank you !!!
شكراً لك على هذه الطريقة وعلى المهنة سؤال هل بي الإمكان صنع فرن للفضة أو الذهب قوة شريط الكهرباء كم و فيما إذا كانت الألواح الشمسية تشغله بدون كهرباء ممكن شكراً لكم من دمشق تحياتي لكم ❤❤
Thanks for the comment.
The power supply is 1500W.
I don't know about other questions, sorry.
I finally got bit by the metal melt bug and want to get into this new hobbie. Im looking it maybe a DIY version but which is better or cost saving, as far as spening money on gas vs electric? Also which melts faster gas or electric? Thanks for any advice and info keep up AMAZING vids!!!
Hello! Thanks for watching!
Welcome to the world of homemade metal melting!
I live in a small residential area, so using a gas or other fire is a bit difficult, so I built an electric furnace.
If your place is large and gas is easily available, I would prefer to make it with gas.
I would also build a gas furnace if I could.
I wish you success and enjoyment!
Hola, buen trabajo con el horno electrico, por favor permitame darle una recomendación, no use ningun tipo de madera cerca del horno, se maneja alta temperaturas y resulta un peligro, cualquier pequeño escape de aluminio fundido provocaría un incendio.
Un Saludo.
Thank you.
É show muito legal mesmo, profissional
Thank you!
how did you find the billet density.? I've heard that vacuum assisted casting, even billet will make for a more uniform/dense result. Great build!
Thanks for the comment!
I did not measure the density of the billet, but the porosity was less than I expected.
hello, to melt aluminum faster, can i use a steel crucible and with the wires more closer or attached to the crucible? which transmits temperature better, a sand crucible or a metal crucible?
Thanks for the comment!
My crucible is made of graphite.
Both iron and graphite are conductors, so it is dangerous to put the wire too close to the crucible.
If you want to melt faster, you may want to increase the power or improve the heat retention.
Is you use distribution strip ?
Yes.
Very nice. It's a well-thought-out, clean build and seems to function as intended. Do you have an idea what the inner volume of the oven is? I am wondering if your stones are 4.5 - 9 - 2.5.
Thank you for comment!
The internal volume is about 1 liter.
The size of the refractory brick is 230 mm x 110 mm x 65 mm.
@@7chome_seisakusyo Thank you, that is helpful to know.
note to myself for future: someday i will try to make this furnace.
Good luck!
Always preheat your molds, u'd get a better results! :)
Thank you,Of course I do preheat.
How much faster did it take to warm up compared to a small 2-3kg furnace?
Thanks for your comment!
I don't know how fast a small furnace weighing 2-3 kg is, but my electric furnace takes about 1.5 hours to reach the temperature at which the aluminum melts.
how about amperage? 20a ?
This coil is 600W and 100V, so two coils are flowing 12A in parallel.
I would like to make 3 coils in parallel, but 18A would exceed the outlet rating of 15A.
I certainly need more power...
hello,question: if place the aluminum oxide at temperatures reaching 1200 Célsios, l con modify its structure, thus obtaining mono crystalline alpha alumina ?
Sorry, I am not familiar with it.
Nice job. 👍 How long it takes to melt aluminum
About 30min.
Thank you!
Why not add another element coil in parallel or cut that one into smaller ones? Was that the limit for the wire gauge and the breaker in the circuit you are plugging it into?

12:00 heatgun for this step does the job for me.
Thank you!!
Mad building , those screws can catch on fire outside that contraption. Know what doesn’t hold onto fire bricks, you don’t drive a hole init for anything molten hot beyond 2090 Celsius
The temperature will not be that high.
And can we adjuste the heat adding any control ?

Please refer to this page.
However, this thermocouple has a heat resistance temperature of 1300°C.

I am very interested in copper melting and it is one of my dreams to try it!
❣️
❣
Ceramic tube is best option for insulation i think
Thank you!!
how many volts and how many amps how many watts ?
100V x 6A = 600W x 2coil = Total 1200W
Can u please tell me. I want to get heat up to 1800c is it possible to get that using this?
Thanks for your comment!
How many degrees you can reach depends on the amount of heat generated by the coils and the heat retention of the furnace.
To reach 1800°C in a less powerful electric furnace, I think you would need to increase the thickness of the firebrick walls by about 3 times.
I would also like to build a larger furnace to melt copper!
@@7chome_seisakusyo Assuming they are using nichrome resistance wire, which is what most furnaces use and what you appear to be using, you can't get to 1800C because nichrome melts at about 1400C. I'm not aware of any electrical resistance heating wire that can withstand 1800C. If I am in error please correct me as I would like to be wrong. It would be much better if the wire could get that hot. To get to those temperatures the options I know are: gas furnace, arc furnace and coal. Arc furnace is cleanest and easiest to build at home, but shock hazards must be accounted for.
Oh, I had completely forgotten about that. You are right.
Nichrome wire melts at 1400C.
If you want to do it with electricity, maybe use an electromagnetic induction coil?
@@7chome_seisakusyo That's a good idea, I'll look into building one. I forgot those existed. Thank you very much for the suggestion,
But the problem is i need this furnace to heat minaral stones . Is it possible to use electric magnatic furnace for that purpose ?
Zašto uopće topiš aluminij?Koja je svrha?
I make mechanical parts from molten aluminum.

Yes, I understand it is cheaper to buy them. Simply because it is fun.
Please la resistance utilisé combien d empere
It is a 100v / 600W resistor, so about 16.67 ohms.

kako??
@@7chome_seisakusyo copper desu
Yes, I would like to melt copper someday!
