For a tempature that high you may have to change crucible types like graphite would work much better for that, because it will get extremely hot also I love the design of it, really well done and even gave me an idea for a similar style, but I'll probably use a leaf blower motor because it's the same one that I've been using. Beautifully designed amd I look forward to seeing what you do with it
Since the "cat got his tongue" there wasn't enough information here to know what went wrong...so what did we learn exactly? This should have been named..."how not to make a foundry"
Ton of thought, design and smarts went into this build. We all learn somehow and that shows here. More solid than any of my previous builds. Be safe and have fun!
So a couple of features I've seen on other kilns is one, a drain hole out the bottom. The kiln is placed over a bed of sand, that way if the crucible fails while the metal is in a liquid state it drains out the bottom and can be collected from the sand. Otherwise you need to get it out of the bottom of your furnace. The other was the barrel that makes the body, if you had done another cut and made a bottom the same way you have a top, then the centre section can be lifted off and the crucible picked up without having to reach down into a hot kiln.
gotta coat it with itc ceramic. more heat efficiency and metal wont stick to it. if liquid metals gets into your refractory cement it will seep into all the pores. then it's scrapped.
No need for a drain hole but you can if you want, if metal spills in the furnace it can be chipped away after it cools down and the refractory can be patched. Making a removable center section is bad news, trust me you’d rather have to reach down in to a hot furnace with your tongs than to blast your legs with 2000 degree heat. I ran a foundry for 20 years so I have some experience with this stuff 😉
@@chrishayes5755 furnace walls should be cast with a layer of refractory over insblock which is high temp insulating foam blocks. Spilled metal will stick to it but once cooled down can be chipped away, it’s by no means trashed.
Yes, even if a gas tank is empty and cleaned, gas will adhere to the surface of the metal and be released by the heat of cutting or welding. A well known cause of fatalities.
From old book they ran blower to direct flow around the circumference not directly at the crucible. Great video I enjoyed your build , looking FWD to watching you re-melt and pour those bearings .
I love how you show what can be done with an angle grinder and a cheap SMAW unit, and basic tools. You don’t need much to start and to build cool and useful equipment. So man people never start because they think they need thousands of dollars worth of tools and equipment. This is proof you don’t. You just need some skill and imagination. And the one thing you’re always in control of: Effort.
the crucible burst because the temperature went so high so fast? You're achieving a higher level of magic!!! Can't wait to see what legendary blades come out of that
Bad luck, a interesting and informative ,video, if you ever have to cast refractory concrete again, it's a good idea to vibrate it, as you cast it, I use a needle gun on the casing, it's amazing how much more goes in, thank you.
I like the valve on the fan to throttle air flow. My local mens shed is building a furnace, using charcoal, we need to modify the design to throttle airflow down a lot as the fan blows way too much air.
04:48 wait wait what sorcery is this? Where'd that smaller pipe thingy come from? Is that for a type K thermocouple? 05:20 Is that refractory cement or plaster? What was that you added to the mix? Graphite? Last but not least that was a crazy looking concoction you were trying to melt... Did you make another video melting it again?
I want to know what you use for your refractory cement if at all possible I made a forger few years ago it didn't last long the internal cement mixer I put in there melted and turned into like a glass lava rock substance
What kind of crucible are you using? I can't see them anywhere online. Also do you have a recipe for the powders you add into the mix of ball bearings?
Was that propane fired with a PID controlled valve and a pyrometer in the heating chamber? How hot do you think you needed it? What is the solution to your unmelted shot? A bigger burner? The burner was that small tube, yes? Thanks for posting! Did you post a successful, subsiquent run? I haven't looked for one yet. Thank you!
Remaining gas in the tank has to be washed out. Even after emptying it, some will remain inside, and a spark could set it off, causing injury or worse.
Hey man thats some good work👍 i just finished building mine but still need to insulate it what did you use for concrete? I see you used ceramic fiber insulation and chicken wire I think?
This was ages ago, still, he says in the description he used refractory mortar. I have some questions too, what's the little widget sticking out from the furnace? The one that looks like a little aluminum cube on a rod with a cable?

My God !!! Good thickness steel!!!
I do appreciate your honesty because you do not hide the image when the crucible bursted. Aside from this, you made a great job.
but the temp of 3002 deg is a bit deceptive
I commend you for showing the crucible failing rather than redoing it for the vid you taught us even more that way thankx for the awesome vid

Im sure its the liquid inside that got too hot for the crucible and bursted out

This isn't a kiln, but a foundry. "Exactly the same, but completely different" is this situation.

That with cutting the tank filled with water can save many lifes. Hope people notice such things. Very ,very good Video!
Respect!

Would have been better had he explained why he filled it with water. I had no idea until I read your comment.
From old book they ran blower to direct flow around the circumference not directly at the crucible. Great video I enjoyed your build , looking FWD to watching you re-melt and pour those bearings .
From an old foundry man I couldn't agree more, and also bringing the temperature up steadily is always worth doing
i wonder why this looks so satisfying ☠️

I kinda want to mail him some gouging rods. I mean he already has the SMAW, so he could make such clean cuts with the right rods.
Adding an air shutter to the incoming side of the blower will give you better control. I absolutely love this channel!!

Cool video!
The main thing is not to give up! 👍
We never give up)😁💪

That was a cool idea but this foundry would eat a lot of gas, I hope.
FZ how much gas did it took to melt this steel balls?
10 liters
Does it work with propane or butane only? I mean if you are using the oxygen or not.
hello, did you purchace the problem after this fail melt of miniballs ??
Thanks for sharing :)
I have a question:
Why do you fill it with water before cutting if you emptied it?
Remaining gas in the tank has to be washed out. Even after emptying it, some will remain inside, and a spark could set it off, causing injury or worse.
I'd like to know: Is that a temp probe? Do you have LPG fixed to a regulator at the other end?
Beautiful
