Just so as you know, dont leave a plug of metal, any kind of metal in your crucible to cool off. When you try to remelt it expands faster than your ceramic and you have a broken crucible.
I agree with your hypothesis on the cracking of the crucible!
Different vegetables oils have different BTU's and burn differently. If you want to make a really good test. Use several different kinds of vegetable oil's, Like olive(and it's different purities) , peanut, canola, corn, sunflower, cotton and liquid coconut oil.
love your testing man! You look at the numbers and instead of stating regurgitated stuff that gets passed around, you put it to the test.
Thanks brother appreciate the positive feedback makes up for all the kicks in the ass i get
Fella the term is "Sacrificial lamb", the stainless disk that is. The crucible cracked because it was made in C H I N A . My neighbor the chemist says that diesel fuel or vegetable oil are about ten percent difference in heat value. Also, when flames are coming out of the hole you are losing heat energy to the air. The silica was attacked by the chemicals in the metal. Just so you know, you would be surprised and the different chemicals put into metals when they are made in C H I N A. When they are machined you need either a fan blowing the fumes away or water cooling to keep funes at bay. That is just what is out there. What you are saying with oxygen is so true. I am amazed that more people do not know that.
I think that’s not the flame coming out of your foundry. It could be the hot air glowing red.
The melting of the white crucible was caused by the slag. The waste is what melts the crucible not the iron.
If you take a piece of cardboard and put it between the crucible and metal plate it will stop the crucible from sticking if that is a issue for you
You had a solid plug of metal that you got hot.. it likely expanded and broke the SiC.
I agree @ 8:52
I will never do that again
Good eye by the way
@@NOBOX7 a remembered lesson from art class ceramics and composite objects shattering when put back in the kiln for the glaze
@@RobertSzasz Great input about the composites , definitely gonna keep this stuff in mind .
Have you tried a ribbon burner with this system?
Got 2 uses out of this crucible before it broke
Your theory would be correct!As to why the crucible cracked!
You should ALWAYS use a reducing flame when smelting your purified metals OR your precision alloys!
Only when you are burning off impurities or balancing out your carbon level should you use an oxidizing flame.
I have 'politely suggested' until I'm blue in the face and thoroughly ignored, despite it being something any person who knows anything REAL about forging and metallurgy has to know as a matter of their daily business.
If you do not use a reducing flame, you ARE 'reducing' the total amount of metal you will get back!
Technically, fuel costs less than metal, especially when you get fuel at commercial prices, [not civilian consumer prices, but commerical prices] so you can afford to burn a little more fuel to save a lot more money.
If you show a business license to a fuel supplier and they see that you are in fact a real commercial business, most of them will refer you to either a special division of their company, or to 'another' company [which is really just a special division of their company] 'not related to them' because its something most of them want to keep secret.
I can purchase bulk fuel from a distributor in my area [found the source from another business, but a B2B directory can often help if you can get one, they are intentionally hard to come by and not readily advertised, so that the public does not know bout them, its actually a giant illegal price fixing trust racket but the government knowingly allows it to keep the status quo] and said bulk fuel distributor will not only sell me large lots of fuel for way cheaper than pumps, the more I buy at a time, the less i pay per unit, and in some cases they will literally drive a tanker to my site, and leave it there until the job is over.
A guy who bought a 310 acre tract of land near my farm put in some turkey houses and they came and dropped off a 5000 gallon tank for him to just use out of until the job was done and he saved a fortune in fuel costs.
Also, yes, you are right about the crucible failure: when you heat a slug of metal, long before it becomes a liquid, it is going to expand.
Sure, it cools from the outside in and does not break anything, but that is ONLY when cooling, NEVER when heating.
Same reason you must hyper-burn lost wax castings rather than slowly heating them.
Wax needs to instantly liquefy and flow away from the contact point of the mold shell, or else the expanding wax will burst the mold.
So all in all, 1, never heat a slug of metal in your crucible [unless its LARGER crucible than the one you first let it freeze in!], because it will break the crucible, and 2, you should always use a reducing flame with at least a 0.5% fuel surplus going out the exhaust of your crucible for control of your oxidization problems. Also, for those who rely heavily on flux to reduce their total slag losses, a speck more fuel is also a lot less costly than a ton of flux!
Delicious DeBlair wow thanks....I learnt so much from your 1 post...
Great input , i suddenly realized the hard way that a reducing flame is a must , i could see boiling slage that wouldn't melt down , now i know why . Thanks for confirming my fears about the crucible , i know nothing about being a black smith so i enjoy your input
@@NOBOX7 I've been at this since childhood, so for me its all old hat, my family has been working metal for 3 generations.
Delicious DeBlair hi
You said you have been working with metals for 3 generations. What do you do?
Have you ever done a foundry ?
Do you know how to make real Damascus Steal
An I am not talking about whacking a stack of different steal
@@tomharrell1954 No I have never worked Damascus steel, it was not something called upon of me.
I have forged blades from high carbon tool steel and from spring steel, but not Damascus steel.
Man I just want to build one of these and put a wok on top it.
Cooper ;)
Wow
