Looking for two pieces of equopemt, propane melt furnace and an atomizer.

I'm looking for a propane melt furnace that can take at least a #10 crucible up to #20. Just a generic propane crucible furnace, nothing fancy. I can wrestle about a size #20 crucible but nothing larger than that.

The other item I am attempting to locate is an atomizer. I will make one if I must, but I would prefer to find one instead, if possible.



Any help would be greatly appreciated.

Thank you

Scott

Hey Scott this is a well made product. HobbyMelter&#8482 Furnace kit - Lionel's Laboratory it will hold a # 10 with no problem. He makes them so he might make a custom one that is larger if you ask. The refractory is easy to procure at plumbing supply houses or if they don't carry it they know where to get it. But buy the cast able refractory don't make it. It is ten times better than homemade and will last a long time.

on the casting forum Lou(same Lou I believe if you read his profile its real close ) has a thread about his tilt furnace. Little tilting furnace

hope this helps.

As for the atomizer contact 4metals he will help. I think he has made them for clients so he might have some plans. or some one with equipment for sale.

Scott you can purchase cast-able refractory from any pottery and ceramic supplier it comes in bags like cement, get the highest temperature refractory used for making kilns.


Hers how I made my furnace, used an old bladder water tank, cut the top off then a hole near the bottom for the torch entry, mixed up a small batch of refractory then poured the floor first let this cure overnight. Next day inserted a plastic garbage can centred then filled it with sand before filling the outside perimeter of the garbage pail inserted a piece of 4 inch plastic into the torch hole.

Then poured in more refractory to fill the gap around the garbage pail, once the refractory had cured removed the sand, now the plastic pail was easily removed, to make the lid i cut a hole centre, then coming in from the sides a few more holes large enough to insert spikes. What i now had looked like an inverted ships wheel, anyhow the idea behind the spikes was to hold the refractory firmly in place inside the metal shell.

You may want to line the furnace with cerwool also known as kaowool before filling it with refractory, its amazing stuff. i can run my furnace for hours and still put a bare hand on the outer shell the cerwool does a good job of keeping the heat inside where it belongs.

Atomizer, not really sure what your looking for are you trying to make cornflakes or shot from your melt, there is already a good write up on this at the gold forum. You can find the article by searching these posts. Gold Refining Forum.com • Information

I ended up purchasing a melt furnace from Kendall for right under $1,500. I ended up building the atomizer myself.

I also just picked up a hydrogen furnace:





I need to alter it for my purposes, it's a beast and then some.

Also picked up a used propane tilt furnace, and in the next few weeks will also have a 40kw (small) arc furnace. I'm just about all furnaced out, unless someone has a line on a small induction furnace, cheap. Lol

Thanks
