Making a 3000℃ electric arc furnace

- An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc.Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking. Arc furnaces used in research laboratories and by dentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can reach 1,800 °C (3,300 °F), while laboratory units can exceed 3,000 °C (5,400 °F).In electric arc furnaces, the charged material (the material entered into the furnace for heating, not to be confused with electric charge) is directly exposed to an electric arc, and the current from the electrode terminals passes through the charged material. Arc furnaces differ from induction furnaces, in which the charge is heated instead by eddy currents.

LOL.. I found directions to make a carbon-arc furnace in an old 1950s "science & engineering experiments for kids" book back in the late 80's.
It told you to get carbon rods from old dry-cell batteries, crimp them in lightweight curtain rods, and use a terra cotta flower pot as the crucible. And the best part? Just wire it directly to your house AC mains power with a cut extension cord, using a glass ash tray, salt water, and lead fishing line weights/sinkers for a rheostat. 😂
Of course, being the smart kid I was, and that nobody in the family smoked, I would just use a spare dimmer-knob light switch in the house workshop as that was a factory made rheostat. And would obviously be far superior to some janky thing made with an ash tray, lead sinkers & salt water.
I did actually strike an arc, for about 5 seconds. Then the dimmer switch melted. 😅
This is indeed an unforgettable experience, but I do not recommend using a sliding rheostat to control the power of the load. It can be used when the load power is small. The resistance will consume most of the power and cause serious heating. The use of a transformer solution is much more reasonable.
@@free_time_g Transformer must be used simply because of safety. The rest isn't even matter.
Pretty cool project! Nicely done with that high voltage arc start and height control!
Thank you for your encouragement, I will make more interesting videos in the future
Looks pretty cool, great job!
Thanks
Bravo.......carbon arc light........great job......cheers
Thanks for the encouragement, I will continue to do some interesting projects
Ciekawy projekt!
dziękuję za zachętę！
I would like to build one of these, do you have any schematics or videos of you making one? I wish I could just buy one somewhere, honestly
Hello sir, I am actually a science and technology content creator in China. This channel is only set up to take into account the global audience. My voice and technical details are removed from the content. If you are interested in the production details of this electric arc furnace and If you are interested in the principle, you can click this link to view the video of my other channel. The default voice of the video is Chinese, but this channel provides English subtitles. You can switch through the settings. In the future, I will use today's artificial intelligence technology to achieve multi-language Voice clone translation to create separate audio tracks!

@@free_time_g thanks man! I appreciate this!
A bit more code for the welding process
Ah, a hollow rod would be best, as then de-carbonization can be achieved and a nitride hard steel can be produced... also titanium can be added with an argon flow.
I assume you are using tungsten rod and this would be best for an add on to an existing electric furnace.. waiting for your upgrade.
Happy grinding of the casts.
Thank you for your encouragement. In fact, that rod that looks like metal is actually a rod of graphite, but with a layer of copper deposited on the surface!
больше распыляет металл , чём плавит . НО работа проделана " моё почтение"

是的呢,这个频道是无解说版本的,如果你是中文用户,看我另一个频道就行了,那个会注重原理讲解以及更全的的细节问题！

最近在制作新的项目，马上就能更新了，嘿嘿！
I work in a steel making company and Iwant to make a mini EAF like yours
Hello sir, are you planning to make an electric arc furnace like mine? I'm afraid this requires some electrical skills because it is dangerous.
Why there is so much static noise in the background 😩
Yes, that is the ambient sound. In theory, I can use audio processing software to reduce the noise, but based on my research, keeping appropriate white noise in the video can make people relax and calm down, because when people can hear white noise, they will psychologically feel that the whole environment is very quiet, and even feel immersive. This is why I would rather use white noise than add background music to create an atmosphere because that will make people feel bad. In recent years, this natural creative method has also been popular among CZcamsrs. And you noticed this detail. I think you are also engaged in the audio-related industry, right? Because photographers will take the picture details of each work seriously, while music or sound effects engineers will focus on the sound details of your content!
Gute Experimente. Besonderer Respekt gilt dem automatischen Lichtbogenzündsystem. Aber die Leistung reicht aus meiner Sicht nicht aus. Ich habe erfolgreich mit einem Industrieschweißgerät mit ca. 70 kW Leistung experimentiert. Carbonstäbe mit einem Durchmesser von 50 mm. Strom von 300 bis 1000 Ampere. Spannung von 30 bis 60 Volt. Dafür ist jedoch ein industrielles dreiphasiges Stromnetz mit ausreichender Leistung erforderlich.
Yes, mine is a household appliance, it is not powerful enough and can only melt some small pieces of metal!
попса! лазерная плавка покруче будет!
Если у меня будут достаточные средства в будущем, я планирую изготовить такое устройство. Спасибо за ваше мнение.
直流电弧炉，底阳极
是的
@@free_time_g 其实，实际生产还是三电极的交流炉更好
that poor welder is not designed to work at 100% duty cycle, it will give up soon if not given adequate cooling period
at full amperage yes, but at 25% it more than likely should be okay
If not, he looks like a guy who would be able to install water cooling for the welder.
The temperature of the carbon rod is very high and water is needed to cool it down, otherwise it will burn out my machine
Yes! This welding machine is very cheap, with a power of about 1500 watts. If it uses three-phase electricity to work, I can use it to smelt scrap iron, but considering the cost, I will not do it!
If it gets hot use two
