PPE for Skimming
Guys, in the Brass and Copper business, we do a lot of skimming of the induction furnaces. The operators wear Aluminized jackets. They find them heavy and cumbersome. Like to know what members are using in place of Aluminized jackets when exposed to liquid metal. Philippe Belanger
Chemistry Lab Management
How does your organization staff the management of your chemistry lab? Is this part of operations or another department? Who is specifically focused on accurate, repeatable, reliable chemistry results provided to the melt shop / caster (not the persons or positions running the tests)?
EBT End Block Spalling
We’ve been experiencing early head-stone failures at ~50 heats, 3 times this year so far. We normally get 120-150 heats between exchanges. After tapping crown removal, the heat affected refractory will readily chip and spall out chunks. Headstone is 70% MgO, 15% Graphite with Al+Si metallics for oxidation protection. Anyone seen this before? Any ideas??
casting / teeming powder analysis
Hi Friends. Is anyone doing in-house evaluation of casting/teeming powder rather than just relying on the vendor assay (and “typical” properties)? There is no real standard, but wondering about testing things like melting point, viscosity, etc. How do you know if something has changed other than to use the product and see that it performs […]
Brick Reclaim
Does anyone know of any companies that buy spent refractory for reclaiming?
Burner Blowout
On our furnace we are having issues with one of our burners failing. We are seeing oxygen and natural gas mix before it reaches the outside of the burner tube (jet) in the furnace. I am looking for some root causes of why this would occur? We have identified a few items: Low natural gas […]
Electrode shoe getting hot.
Has anyone ran into issues in the past with their copper shoe’s contact pads on their mast heads getting hot during operations? We’ve struggled with this the last couple years, and have had to change them out a lot. We have gotten a lot of debris build up at times, and we do inject lime/carbon […]
Pb pickup – CaSi treatment
Hi. Seeing some Pb pickup after CaSi wire injection recently. Tested the CaSi and the sheathing but not finding the Pb source. Has anyone seen this before? Brendan
Operation during high power prices
Does anyone change the EAF power program or the pace of the shop to run differently when electricity is very expensive from how you run during periods of normal/low pricing? What sorts of changes do you make? I’m specifically asking about situations where the furnace continues operations, not when/whether to shut down. Thanks!
Crane Magnet Lock Out
What lock out procedures does everyone use for locking out and disconnecting the crane magnet? Does anyone use a light system for when there is power or not to the magnet?
