Patent ID: 8899305

Claim:
A crystallizer for continuous casting, comprising: a monolithic structure defined by lateral walls in the thickness of which channels are made in which a cooling liquid flows, wherein the channels are geometrically sized so as to, in a zone astride a meniscus, increase a transit speed of a cooling liquid, wherein in at least some of the cooling channels the transit speed of the cooling liquid is greater in the zone astride the meniscus compared to a zone below the zone astride the meniscus, wherein the channels include: in the zone astride the meniscus, a plurality of first channels having a larger diameter, and a plurality of second channels having a smaller diameter, wherein the smaller diameter defining a reduced passage section of the cooling liquid with respect to a passage section defined by the larger diameter, and the second channels having the smaller diameter are disposed alternatingly between the first channels having the larger diameter, and in the zone below the zone astride the meniscus, there are only the first channels having the larger diameter.
