still, for continuous casting of a stalstreng with essentially rektanguler tversektion

摘要

Surfaces are reinforced against loads applied to one side by subjecting the opposite side to intense and continuous cooling to establish thermal stresses. This technique is applied in the continuous casting of slabs and billets by giving the slab and billet an initial concavity or at least restraining same from initial convexity and then subjecting its outer surface to the action of continuous and intense coolant sprays.
