Question about a bad pour day at the plant in Toledo
Last Tuesday, our main induction furnace had a partial refractory failure during a 1600-degree bronze pour, causing a massive slag boil that ruined the entire batch and shut us down for 8 hours while we did emergency patching. Anyone else had a refractory issue creep up that fast?

We had a 12-inch thick lining in our arc furnace at the old Gary Works that looked solid on the weekly inspection. I used to think those things gave you plenty of warning. Then one Tuesday afternoon, it just let go during a heat, and we had a breakout that took out the water-cooled cables. That single shift changed my whole view on how fast a hot spot can turn into a full failure.

We ran a 3000 ton aluminum holding furnace at the old Kaiser plant that would eat through a lining in under six months. The real trick is checking the cold face temp with a laser gun every single shift, not just on inspection day. You get a spike of even 50 degrees on that shell, you know you've got maybe two heats left before it goes. Ever think about adding that to the operator checks?
