Reducing Radiation Heat from Induction Furnace on Lifting Magnet

[dormo715]

http://lookpic.com/O/i2/73/DYktKEGg.jpeg Hello Dear Friends

We produce Lifting Electromagnet for Steel Scrap charging of Induction furnace, bottom plate of

electromagnet is made of Stainless steel .

my question :

Can We use AL OR SILVER Spray for Spraying bottom plate that Radiation heat is reflected ?
Is this method useful ?

OR Can We use material that absorb radiation heat ?

Our purpose : We need a way that radiation heat , reflect or absorb

by this way , amount of heat transfer by radiation to Lifting Electromagnet is decrease

and Life of Lifting Electromagnet insulation increased.

Thank Youhttp://lookpic.com/O/i2/943/LJEUNM4z.jpeg

Ferrous scrap melting temperature is high enough that "reflection/absorption" of radiant energy is "problematic;" can you sell your customers an inert gas "door/portal" through which to charge? There are such things limiting escape/exchange of "heated/cooled" air at entrances to high foot traffic buildings. The object of the exercise is to lengthen the lifetime of electrical insulation for the magnet?

Thank You Dear for your opinion , unfortunately we can't use inert gas , because for Extreme conditions of lifting magnet , welding of bottom plate was cracking .(impacts in high temperature , weight of lifting magnet approximately : 3 to 4 ton) , when crack : inert gas was exited .

For reduce convection heat transfer , We use double bottom plate(similar to Double glazed window) . minimum space between plates is 50 mm . Is it useful for decrease radiation heat ? (I guess is not useful :( )

Yes The object is to lengthen the lifetime of electrical insulation for Lifting magnet
