Reducing Radiation Heat from Induction Furnace on Lifting Magnet

AI Thread Summary
The discussion centers on methods to reduce radiation heat affecting lifting electromagnets used in induction furnaces. The original poster inquires about the effectiveness of using aluminum or silver spray to reflect radiation heat or materials that absorb it, aiming to extend the insulation life of the electromagnet. Participants note that the high melting temperatures of ferrous scrap make reflection and absorption problematic, suggesting alternative solutions like inert gas barriers, though these are deemed impractical due to welding issues. The use of a double bottom plate design is mentioned as a potential method to reduce convection heat transfer, though its effectiveness against radiation heat is questioned. The overall goal remains to enhance the durability of the electromagnet's insulation under extreme conditions.

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/absorbtion" 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

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
