At least you're OK. Is it dangerous when that happens?
This is not my Caster, it's at another mill.
Usually, a breakout looks like right around 3 minutes on this video.
When this happens, the ladle gate is shut, stopping steel from coming out of the lade.
In this example, the ladle gate "froze". And metal continued to pour.
