What is it?
Slivers are segments of steel that have been torn from the steel and rolled onto the surface of the metal. This defect is most common in low strength steel which can easily tear due to incorrect or high speed rolling processes. Slivers can also start from defects that were not previously removed by conditioning. They are commonly mistaken for shearing and laps. They can also be random, pulled up areas of the steel also referred to as pull slivers or lamination. This can be caused by a locked-up segment roll at the continuous caster that creates a random gouge in the slab.
