The first stage of any reline: breaking out the old lining with jackhammers, remote demolition machines or ladle wrecking rigs, and hauling out the rubble. Tear-out is hot, dusty, noisy work, often started before the vessel is fully cool, and it is where crews inspect anchors, shell condition and the safety lining. Spent magnesia-chrome brick and used ceramic fiber carry special handling and disposal rules.
Tear-out on the kiln starts at six, demolition machine first, then hand cleanup at the tires.
