Plant trials conducted at ArcelorMittal Dofasco Inc. revealed that the slab cooling cycle at
the caster exit and slabyard, and reheating inside the hot mill furnace, had a strong influence on sliver formation on some hot rolled coils. Laboratory experiments were conducted to understand the influence of slab microstructure evolution on defect formation. A mechanism for sliver formation is proposed.
