development of Magnetic field on kiln shell while replacement
Dear Sir,
In our recent kiln shutdown we hav planned to replace part of shell ..When shell was cut and put new shell it was observed that there is magnetic field near new shell & old shell up to distance of 200 mm on both sides of joints .
could you tell me the reason of magnetic field developed and which is not allowing welding with rectifier .so, we put AC welding with . normal electrodes and could get succeed .
pl let me know the reason of such a high magnetic field up +20 to -20 gauss.

re development of Magnetic field on kiln shell while replacement
Hi
If your kiln is installed in north-south direction there is chance of kiln shell getting polarized on long run. Any iron piece kept in north-south direction for long time will get polarized and may develop magnetic properties.
