Hello everyone, @SJWCasting here!👋🏻
#metals #copper #devilforge #metalcasting #melting #casting #bigingots #scrapping #brass #aluminum #nordicgold #vevor #scrap
This week I put the two furnaces I have to the test!! Vevor vs. Devil Forge.
The results surprised me a little bit.
I known that the Devil Forge would be faster, but I didn’t thought the Vevor furnace would be so close to the Devil Forge.
Devil Forge: under 18min
Vevor Furnace: just over 18 min
The Vevor Furnace was cheaper to run, it didn’t need so much gas as the Devil Forge.

By selling merch, I can earn a little bit money (not that much..) and put more in the channel.
Also, I can save more of my own money so we can move to a bigger place.
With a bigger workplace because it’s getting claustrophobic in the garage,
with other projects I’m starting soon, I’ll need more space, much more space!!!
Everything you see is created by yours truly 😁. I spend much time on this. Ordered a bunch of stuff to test and adjust. Now it’s all ready!! I will release more merch in the summer, limited edition!! And more after, but I need some inspiration first😉.

Bing Copilot says: "The three approaches you've mentioned are indeed common methods to reduce or eliminate voids in copper pours during smelting: 1. **Temperature Control**: Precise control of the temperature can help ensure that the copper melts uniformly, reducing the likelihood of gas entrapment and void formation. Overheating can cause excessive gas absorption, while underheating can lead to incomplete melting and poor flow, both of which can create voids. 2. **Vibration Table / Pad**: Using a vibration table or pad can help to agitate the molten copper, allowing trapped gases to escape to the surface before the metal solidifies. This method is often used in conjunction with other techniques to enhance their effectiveness. 3. **Use of Additives (e.g., Copper Phosphorus)**: Additives like copper phosphorus can act as degassing agents. They help by combining with the oxygen to form stable oxides, which can then rise to the surface of the melt. This process reduces the oxygen content in the molten copper, thereby minimizing the potential for voids caused by gas entrapment. In addition to these methods, you might also consider: - **Fluxing**: Using a flux like borax can help remove impurities and oxides from the surface of the molten metal, which can also contribute to void formation. The flux can absorb these impurities and facilitate their removal as slag⁵. - **Protective Atmosphere**: Introducing an inert or reducing atmosphere during the melting process can prevent oxidation and reduce the formation of voids due to gas entrapment. - **Pouring Technique**: The way the molten copper is poured into the mold can influence the formation of voids. A steady, controlled pour that minimizes turbulence can help prevent air entrapment. Each method has its own set of considerations and may be more or less effective depending on the specific circumstances of the smelting process. It might be beneficial to experiment with a combination of these techniques to determine the most effective approach for your particular setup. Remember to always prioritize safety when working with molten metals and high temperatures."

@jaredjones6570 6 дней назад

I had prompted it with: "I'm trying to come up with ways to remove voids from copper pours during smelting. So far, the Internet has recommended three approaches: 1) Temperature Control, 2) Make a vibration table / pad and set a stack of fire bricks on it and put the smelting furnace on that, 3) use additives such as copper phosphorus to degas the copper in the crucible before the pour"

@SJWCASTING 6 дней назад

I’m gonna try controlling the temperature a bit better and use copper phosphorus when I remelt those “bad” ingots. And pour more calmly also could help 🤔

@jaredjones6570 4 дня назад

@@SJWCASTING Another thing I noticed while comparing your video to some others' videos is that you poured the copper into the center of the graphite mold. Maybe it would be less turbulent if you poured from the side of the mold. I'm just getting into smelting, myself. So I've been watching a lot of videos on the topic lately and it seems to me that the people that poured on the side experienced less bubbling on the surface compared to other methods of pouring. But again, I'm no expert. Haha. Good luck with your pours! I appreciated this video

Add borax detergent and it will fix it👌 borax may ruin the graphite crucible after extended use, try sprinkle some borax on the molten copper after it’s in the mold. Preheat the molds also

@markbrinton6815 Месяц назад

when I was taking casting classes, we would put the ingot molds on top of the furnace to heat them. Als, the molds were made of Angle with end plates. Really easy to remove.

@SJWCASTING 15 дней назад

I do that too 😉. I’ve used and abused these molds for a while now so it’s a bit harder to remove ingots 😅

@curtwarkentin2887 8 месяцев назад

Im kinda guessing the Devil Forge and Vevor are equal for performance. But the difference is in the accessories. DF i believe has more and better options available as a kit. But you also pay a premium for those extras. With DF you are paying for the experience of the builder to give you a more refined so to speak kit so the crucible and things will last longer. Vevor seems like a box store kinda thing where they want cheap and big numbers. Product doesn't have the expertise behind its kit like the round tongs for picking up the crucible from the furnace as compared to pincers to pull it up out of the vevor. Correct me if im wrong but your results kinda show they are very similar in performance but longevity id have to bet on DF. The round tongs will be easier on the crucible I've read in other video comments.

@SJWCASTING 8 месяцев назад

I couldn’t have said it better myself 😉. I agree with you. They both get the job done but DF is more premium.

@terrydowning6365 2 месяца назад

Are you pre-heating your molds? I've seen other RU-vidrs do that, it might help. 😀✌❤

@mattyal9347 10 месяцев назад

I paused as soon as you asked we viewers whick forge is better. Three factors come to mind. The placement of the fuel tube in which they both seem to create a vortex, the quality of the kaowool which we have no way of knowing and the thickness of the kaowool. So my moneys on the devil forge

@SJWCASTING 10 месяцев назад

I didn’t think about the thickness of the kaowool 😅.

@pointeisabel Месяц назад

Those bubbles are usually formed due to impurities in your metals, melting soldered copper pipes or any kind of waste metal will cause these porosities

@SJWCASTING 15 дней назад

Strange because these are from cables, clean cables 😅

@1docg 5 месяцев назад

When melting copper, borax can be used as flux. Borax can help with the following: Improving flow: Borax can improve the flow of molten metal when added during melting. Preventing oxidation: Borax can help prevent oxidation. Drawing out gasses and oxides : Borax can draw gasses and oxides out of molten metal. Coating the crucible: Borax can prime the crucible so that metals don't stick to the inside during cooling. Removing impurities : Borax can float to the surface of molten metal, bringing up impurities that can be scooped off.

I normally use it for brass melts..

@SJWCASTING 4 месяца назад

But I think I’ll use it to “clean” my copper

@Mystic-Mountain-Morphs Месяц назад

I have only done probably 100 copper bars my self and just recently started doing videos on my snake channel here but i have never seen this issue. I use a cutting torch to heat my molds and so far only have used vevors electric furnace / Smelter. So maybe your copper is to hot? Idk it could be a lot of different reasons. I am fairly new buti have never used flux i think useing the cutting torch to heat molds has really made my bars smoother. Who knows like i said i am still very new to this i know the electric vevors only get to 1150c so temp may be an issue who knows awesome video buddy keep it up

@SJWCASTING 15 дней назад

Yeah I think I got the copper a bit tot hot. Usually I only use flux with brass. I don’t like using the electric furnace, it takes to long and could damage it doing long, hot melts. Thank u!!

@SJWCASTING 10 месяцев назад

Cool down the copper before pouring? I’m not sure how I’m gonna make a vibrating pad 😅.

@justanothermeltingchannel 10 месяцев назад

Interesting video. I wonder how the vevor furnace would compare if you were able to regulate the propane pressure better so it would be on equal terms as the Devil-Forge.

@SJWCASTING 10 месяцев назад

Thank you! Hmm, that’s a good point🤔. I’ll take a look at regulators and do an other comparison 😁.

@mattyal9347 10 месяцев назад

Might be asbestos from the wire coating causing the bubbling over. I don't think your forges will get hot enough to disintegrate it if thats what it is. I think it takes 2000 to 2500 degrees farenheit... and lots of ventilation!

@mattyal9347 10 месяцев назад

I have an idea that the contamination is floating to the top,cooling and causing it to seal. Not good for molten copper. So make a long narrow tube shape in tightly packed sand. Then remelt the problem copper and let it cool. I suspect if you cut 1in ch off the top the contaminated copper will be removed

@SJWCASTING 10 месяцев назад

I sure hope not! I have a bunch more of those cables. The devil forge should go up to 2640°F, so the devil forge should burn everything off 🤔

@SJWCASTING 10 месяцев назад

Thank you, I’ll try that!

@royalgaming7216 10 месяцев назад

What's funny is I actually commented on skullers original video where he was having this problem and I'll tell you the same thing I told him looks like you need a degassing agent which for copper is phosphorus and you can buy something called phosphor copper which has phosphorus added to it which will react with the probably hydrogen that is absorbed into the metal but the downside is the one good place to get high quality phosphor copper is Belmont metals (that i know of) and you have to buy at least a certain amount so it's a little pricey or you can go to the poor man's method and you can buy some phosphor copper brazing rods now they're not pure copper they have a bit of silver and some other stuff in them and I actually bought them because they reduce porosity in the metal which is great for sand casting which is what I do but I think that's what you need

@SJWCASTING 10 месяцев назад

Yeah I know he had the same issues 😅. Oh ok, so how many copper phosphorus rods do I need? Is there an indication of some sort to know if it’s enough?😉. Found 5 rods for €4 ($4.38).

@SJWCASTING 10 месяцев назад

Thanks for the tip btw!!!

@royalgaming7216 10 месяцев назад

Sorry for the late response, I didn't get a notification. But the amount that you need should be very very small from what I was reading it's about 1.5 Oz of phosphor copper per 100 lb of metal. What I was always told was to cut a grain of rice-sized piece and put two for every pound since the amount of phosphorus is only 7%, in the high-grade stuff is about double that so you would use only one grain of rice size piece per pound. but I was watching a video from an old guy that was in the Navy and worked in a Foundry he said it's also important to dunk and stir so what I would do is take copper foil put the pellets inside attach that to a graphite stir rod with some copper wire and then dunk and stir it, don't forget to preheat it. though that may not be necessary I don't actually know it may just work if you just put it in and stir. found the video here it is where he is talking about how they would use phosphor copper ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SsEgKuoFWaw.html

@royalgaming7216 10 месяцев назад

And one more thing I'm just going to mention again I've never had this problem with the bubbling over like that but from my research this is what you would do. And I would definitely recommend doing some of your own research on this. like I said I just do it to reduce porosity in sand castings. good luck though😁👍

@SJWCASTING 10 месяцев назад

@jamescueva305 6 дней назад

Could it be the lack of borax causing the holes? Did you heat the molds before pouring?

@SJWCASTING 6 дней назад

With clean copper I didn’t use borax. I never used borax with copper but I think I get the copper to hot. Yes, I always preheat the molds 😉.

@MrBacchus-cz4kk 10 месяцев назад

You can stir the copper in the crucible with a stick and the wood will help the degassing and you just scrape the ash off the surface.

@SJWCASTING 10 месяцев назад

Just a stick? Now that’s something I just need to try out!

@jimcatanzaro7808 7 месяцев назад

@lodebleux7241 5 месяцев назад

looked like the mold you emptied and refilled did not have that problem. That mold was warmer and the last copper you poored was a bit less hot. So could be something with to do with to hot copper to start with or to much cooled down molds.

@SJWCASTING 5 месяцев назад

It could be the copper was a bit too hot, I didn’t check the temperature when I melted the copper😅.

@brandt-heiss 10 месяцев назад

I saw that bubbling copper the first time now. Have you measuring the temperature of your molten copper? Maybe its a little bit to hot... Your copper reminds me on boiling water... I mean the devilforge brings the metal easily on 1400 degrees Celsius. But thats just an idea. Greetings from Bavaria.

@SJWCASTING 10 месяцев назад

No I don’t measure the temperature of copper, when it’s molten, I pour it 😅.

@Truck_Company_84 4 месяца назад

So as a beginner, which do y’all recommend? I myself am leaning towards Devil Forge, but the Vevor seems to be a good price as well.

@SJWCASTING 4 месяца назад

It all about how much you want to spend on it. If you don’t want to spend a lot of money just to try it, go for the vevor melting furnace. It’s as good as the devil forge in my opinion, just choose the right size 😉. Devil forge is a bit more expensive but I’ve used it for 2years every weekend and it still works like new (it sure doesn’t look so😅).

@wvcruffler123 3 месяца назад

Why do you quench the ingots rather than let them cool on their own? Is there a benefit to hardening them?

@SJWCASTING 3 месяца назад

That way I could clean them faster, didn’t had the time to let them cool off and then clean everything up 😅

@alexbeebe2652 3 месяца назад

You may need to melt it all down, flux with borax or whatever is recommended for copper, and skim the surface of all dross before pouring. Also try preheating your molds really well before pouring they need to dry and off gas.

@SJWCASTING 3 месяца назад

Yeah i found a flux for copper but I forgot how it’s called. I always preheat my molds pretty good 😉.

@1988Mauritz 10 месяцев назад

maybe you could try "whisking" it a few times when its melting if you need to refill to crucibel or do it a min before the pour to maybe let some gas out. thats just a thought i never tryeded it myself

@SJWCASTING 10 месяцев назад

Whisking doesn’t help that much sadly. I tried it in other video’s 😉.

@1docg 4 месяца назад

Are you accumulating all that copper to sell? Is there a premium price for copper ingots compared to raw un-smelted scrap? Does it pay to create the ingots over just cleaning the copper? Or do you do something special with the ingots? I'm thinking about the global copper shortage here.

@SJWCASTING 4 месяца назад

Yes, I do but not now. I’m waiting for the day that copper skyrockets 😁. Oh yeah, scrapyards pay scrap prices. If you sell them online, you could ask up to €30/kg at this moment. The cleaner the ingot, the more you could ask for it. I’ve seen copper ingots (0,400kg or 1 pound) for €20-€25..
