Torch Cutoff
Top view of a torch cutting station of a two-strand slab caster.

The oxy-acetalyne torch cuts across the strand to make slabs of the desired length.

Side View of slab resting on support rolls, as it exits the torch cutoff process (note that sparks from the torch penetrate through the slab bottom)
While it is cutting, the torch cutter must move with the strand; in this case along treads.
