Continuous casting of steel is the process where molten steel is solidified into a semi-finished billet, bloom, or slab for subsequent rolling in the finishing mills. Effective water cooling of continuous casting rolls is critical.

In addition, deposits on roll surfaces cause picking or sheet marking.
