Continuous castingWikipedia
Continuous casting also called strand casting is the process whereby molten metal is solidified into a "semifinished" billet bloom or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s steel was poured into stationary molds to form ingots.Since then "continuous casting" has evolved to achieve improved yield quality
