materials for very high temp.

[PaoloColombani]

What if it's in graphite? ? ?

It would burn. always that there is no way to cover it with a layer of material resistant to such temperatures and able to isolate it from oxygen (but here I fear you enter the field of experimentation). In fact, although graphite has a very high melting point, it also has a relatively low combustion tempering. burns very slowly, but burns. try to believe! for sure of what I write I just tried. Since lavoisier times it is known that even the diamond can be burnt (other allotropic form of carbon). I take this for real so, without trying to verify it.

use for years to melt steel
reach the 1700°
It's eating.
but not burning
and I guarantee that you will shoot in the oven also 5-6000 m3/h oxygen. . .

for me the roads are either the use of refractory stainless steels by providing a proper cooling circuit or the use of nickel-based super alloys (with exorbitant costs).

from the description it would seem part of a reactor of a pirogation system, for correctness to my client and for short-term constraints I can not tell you how they solved, but I can tell you that the agitator is not a particular that desta worries, obviously have diametrically opposite solutions to yours.. .

Yeah, sure. graphite is a great material to produce the electric arc, in fact it is a great refractory and is conductive, unfortunately it is also a fuel. This is why any graphite electrode (the link is no exception) is to be considered a consumable.

as I said the reaction of oxide reduction is slow and is not spontaneous (it is also deducted from the balance of the entalpies in play in the reaction) but slow, makes graphite not suitable for mechanical applications within a combustion chamber.

but do you really see a graphite tree with blades spinning charcoal?

I did not remember the application :redface:

In fact it is considered "consumer" material, if it evaluates its consumption, it tries to reduce it etc. . .

If you have to keep everything the same, and if the steel can't do it, the only thing is to go on the alloys for high temperatures like the iconel.


Otherwise the most natural solution is to turn or shake the oven from the outside without having to put pieces of metal in the middle of the burning charcoal

Uhm, ho un problemaone. ...

but at the end what solution did you decide?

 

[ipotemusa]

but at the end what solution did you decide?

decided to maintain the 310s, modifying shape and above all points of crawling of the tree
in pennies, before it was a simple ke tree crawling on a bushing on another counter-rotating tree, now I am a hollow tree and the other inside.
Sperem... .
Thank you all.
