Any recopies for 5000 degree refractory in steel making?

[J. Bennett]

Just wondering.
I have quite a few that can stand that heat, but not many that can take molten iron/steel, and that won't impart gunk into the molten metal.

Also, if you know how to bond MgO, please speak up. Thanks, Jerry

5000 F?

what alloy are you melting that high?
Most steel will melt at 2500F (1370C)

these guys have everything
Refractories-west, Inc.
they are the former AP Green Pueblo Refractory Plant purchased by the employees when it was slated for closure
(there is quite a lot of history there the initial plant being brought online in 1890)

Um, well..
First, thanks for that awesome link. I really can use that. The MgO bricks are great! *kid in candy store*
As far as the temp requirements, well thats sort of my plane, so to speak. BTW, "Ice Czar" . Now that's ironic.
Thanks again Ice, for the resource! Jerry

ex operations manager in charge of ice for the Great American Beer Festival (13 years) been my online nic since I started

not too strange since Im a thermodynamics geek, happy to help

hmmm... 5000F, browns gas?
tungsten takes 6170F

[J. Bennett]

Well then.
Thermodynamics eh?
Ice and fire. Nice.
here is an mpg of my early steel making. A 10 pound charge of thermite..
It was too wide, and thus made a too large of a thermal mass. Melted clean through my 5000 furnace lining.

I have since learned how to tame the dragon. but try not to get cocky.

BTW, 6170 ain't no thang.. Back atcha

[Ice Czar]

not to mention all the practice your getting if you forget the combination to your safe

you get an A+ for safety gear

[J. Bennett]

Distance is the best safety gear
EDIT: Around 5% of my runs, that is iron, gets boiled off.

what are you casting? or are you?

[R Funk]

High Carbon Steel Melts at Approximately 2600F and low carbon steel melts at 2800F Often cast steel is poured at a few hundred degrees hotter for adequate fluidity. This is why high carbon steel burns easier when forging than lower carbon steels.

I suggest going out on the web to learn of available refractories.

Low alloy refractory steel. Stuff that does not exists in the text books....yet

Ive been able to alloy a rhenium alloy, and other transition metals, with other refractory elements, via exothermic reaction.
I'm being coy because I have patent pending.
EDIT: R Funk, ther is no carbon in this steel. It makes for a higher playground..
