[TheForge] Gun Burners (AKA fan blown)

[Chuck Robinson]

Hey Mikey,
I'm using 4 propane forges and a propane fired salt heat treating furnace.
#1 is a blown vertical birdcage forge that is used for knifemaking and 
forging Damascus.

#2 is a 30" x 16" blown horizontal pipe forge with a Mizou cast floor  and 
inswool shell lined with satenite. This is the forge with the ribbon burner.
It is used to weld large powder Damascus billets  and heat other large 
billets for making hammers etc.

#3 is a stainless horizontal forge with arched ceiling about 1/2 the size of 
#2.
It has 3 "T" Rex atmospheric burners and a castolite cast floor. I built it 
to test out and tweak atmospheric burners. Use it occasionally for  lower 
temp multiple forging ops.

#4 is  a S/S 1/2 beer keg sawed in half at the middle, and completely lined 
with castolite.
one end has a 6" square hole in it and the other end has a3' round hole in 
it for a "T" Rex foundry atmospheric burner.
It is used exclusively for heat treating the adjustable blade anvils I make 
for the blade makers.

I've been pretty disappointed with atmospheric burners for the higher heat 
ranges I often need. So I only use them for temperatures 2200F or cooler.
I still plan to try to coat my forges with the Zirconia solution you 
recommended.
How should I apply it over the satenite?
can it just be sprayed as a final coat?
I've been using an optical pyrometer to test the forges and still haven't 
gotten the atmospheric burners to exceed 2350F. I'll test them with the 
Zirconia coating to see the improvement.
