I have made a number of these furnaces both in workshops and for friends.
Ceramic fiber bronze furnace.
High density ceramic fiber board ceramic fiber furnace chamber.
Our story why allied we re dedicated to being there for you.
In all furnaces placing ceramic fiber between the crucible and its base or wedging ceramic fiber against the top edge of the crucible also will cause oxidation and cracking in those.
The lining on my furnace should take 2700 degrees.
Ceramic fiber is a kind of high temperature insulation materials with low thermal conductivity nowadays they are widely used in all kinds of industrial furnace systems which has changed most furnace lining design as a efficient energy saving and high temperature resistance material.
2300 f ceramic blanket can be used but expect a shorter life.
This propane melting furnace and it s accessories is made from mild steel and it s burner nozzle is made from ss 304 material.
Its heating zone is fully insulated with 1 inch thick refractory ceramic fiber and it s cover insulated with 2 3 inch refractory ceramic fiber which can resist temperature up to 2600 f 1425 c.
You cannot use plain concrete or substitutes this can be dangerous.
Brother ceramic fiberboard is made of high purity alumina fibrous and alumina powder to be formed and fired in special equipment with the advanced patent process can withstand temperature up to 1800 celsius.
This propane melting furnace and it s accessories is made from mild steel and it s burner nozzle is made from ss 304 material.
Like my original furnace the helium tank furnace has a castable refractory floor and lid and is lined with ceramic fiber blanket.
In a fuel fired furnace operating the burner with excess air and direct flame impingement on the crucible surface will produce damaging oxidation of the crucible.
Allied offers a variety of engineered ceramic solutions that can be supported globally by our sales and service networks.
This propane melting furnace and it s accessories is made from mild steel and it s burner nozzle is made from ss 304 material.
Of bronze or 10 lb.
Its heating zone is fully insulated with 1 inch thick 4 layers of refractory ceramic fiber and it s cover insulated with 4 5 inch refractory ceramic fiber which can resist temperature up to 2600 f 1425 c.
It just holds a 10 crucible and so it will melt 30 lb.
Bronze is poured at around 2100 degrees f but the furnace lining especially where the flame is hitting it gets much hotter.
They have proven to be reliable and efficient.
Generally speaking there are two types for bulk ceramic fiber manufacturing one.
Advanced ceramic custom solutions allied mineral products is a global manufacturer of monolithic and precast refractory ceramics.
