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.

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

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.

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

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.

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.

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

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 3 ай бұрын

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 3 ай бұрын

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 2 ай бұрын

@@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

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!

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.

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

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 Жыл бұрын

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 Жыл бұрын

Thanks for the tip btw!!!

@royalgaming7216 Жыл бұрын

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 kzfaq.info/get/bejne/idl1mq6m1Ky7kas.html

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.
