Reducing Radiation Heat from Induction Furnace on Lifting Magnet

In summary, the conversation is discussing ways to decrease the amount of heat transfer by radiation to a Lifting Electromagnet used for melting ferrous scrap in an induction furnace. The suggestion of using an inert gas "door/portal" for charging is not feasible due to welding cracks in extreme conditions. The use of a double bottom plate with a minimum space of 50 mm is being considered to reduce convection heat transfer, but it is not believed to be effective in decreasing radiation heat. The main goal is to prolong the lifespan of the electrical insulation for the lifting magnet.

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

Related to Reducing Radiation Heat from Induction Furnace on Lifting Magnet

1. How does induction furnace radiation heat affect lifting magnet performance?

Induction furnaces can produce high levels of radiation heat which can impact the performance of lifting magnets. This is because radiation heat can cause excessive heating and damage to the magnet's components, leading to reduced lifting capacity and potentially dangerous situations.

2. What are some methods for reducing radiation heat from induction furnaces on lifting magnets?

There are several methods that can be used to reduce radiation heat from induction furnaces on lifting magnets. These include using heat-resistant materials for the magnet's components, implementing cooling systems, and positioning the magnet further away from the furnace.

3. How can the use of heat-resistant materials help to reduce radiation heat?

Heat-resistant materials, such as ceramic or refractory materials, can withstand high temperatures and protect the magnet's components from excessive heat. This can help to prevent damage and maintain the magnet's lifting capacity even when exposed to radiation heat from the furnace.

4. What are the benefits of implementing a cooling system for lifting magnets near induction furnaces?

A cooling system can help to dissipate the heat generated by the induction furnace, preventing it from affecting the lifting magnet. This can help to maintain the magnet's performance and prevent damage to its components, leading to increased safety and efficiency in the workplace.

5. Can the positioning of a lifting magnet near an induction furnace affect its performance?

Yes, the positioning of the lifting magnet is important when it comes to reducing radiation heat from an induction furnace. Placing the magnet further away from the furnace can help to minimize its exposure to heat and reduce the potential for damage. Additionally, positioning the magnet at an angle can also help to deflect the radiation heat away from the magnet's components.
