Lunch

1 p.m.

Sources Reoxiation and Why To Avoid
Sunday Abraham, SSAB Iowa Inc.
To produce high-quality cast products, steel must be protected from reoxidation. Reoxidation can occur in the ladle, at secondary ladle metallurgy operation, and also in the transfer operations from ladle to tundish and tundish to the mold. Various techniques will be described that can be used to minimize reoxidation.

Caster Secondary Cooling and Water Treatment and Spray Nozzles for the Steel Industry
Ian Deeks, Nucor Steel–Arkansas
The surface and internal quality of continuously cast slabs and billets is intimately linked to the caster design and to the operating and maintenance practices employed in the continuous casting process. Common causes for five classes of continuous casting defects (longitudinal cracking, transverse cracking, slivers and lamination defects, internal cracking, and segregation defects) will be reviewed and linked to these design and practice influences.
