Conclusions

  1. 1.

    Sidelining failures can be controlled by sufficient cooling to form a layer of frozen bath over the side walls.

     
  2. 2.

    Transverse cracks do not by themselves cause tap-outs. With adequate side shell reinforcement, longitudinal cracks do not lead to tap-outs.

     
  3. 3.

    Cracks, growth, hydrodynamics, and magnetics are involved in pothole formation.
