This clip from a 2023 iron pour at the University of Southern Mississippi shows what happens when a large furnace develops a leak at the bottom slagger.
With that much molten iron inside, the back pressure makes it nearly impossible to stop the leak by adding more bot — it will eventually break through.
The solution is to act fast. The crew taps the furnace early, releases the pressure, and regains control. After that, the furnace bottom slagger securely bolted and well of iron brought back up to continue the pour.
A great example of quick thinking and experienced teamwork.
