Sparking between electrode contact clamp & pressure ring in carbide furnace elec

so high power!

you mean there is a sparking between joints? its may caused by corrosion of water you said.

Try to clean rust carefully. I think. and tight the screw.

just an idea from principle, I hvnt met such high power equipment.

who supplied and who designed and who installed this furnace? Somwehere in there is a person who knows how to sole this problem. A 30 MW electric furnace with 'sparking' can soon become a large problem.

Suggest you get in touch with that the above people in that order. These can also fill the air with carbon monoxide. I hope you have detectors?? or you may need pallbearers

Q1 30 MVA-Closed top Ferroalloy Furnace?

Q2 There is a supplier/Designer-operation-experience consultant? What does he do/say?

Q3 There is monitoring of temp. on upper zones?

Q4 Is it the nominal 400ºC as should be -or shooting up to 800>900?

If it is that hot, you need to solve feed distribution problem. Thre surely are dead zones"Holes".One thing will lead to another.

You should not ignore these telltale signs.

That is what Instrumentation is all about.
