CRYSTALLISER

摘要

A crystalliser for continuous casting of blooms and billets, provided on the external surface with grooves or channels, made for example by milling and in which cooling water flows, said grooves being appropriately dimensioned and being distributed so as to obtain an optimal cooling of the internal wall of the crystalliser thus making its temperature nearly uniform. Advantageously, said crystalliser presents a considerable stiffness despite of being not very thick.
