This research studies the position of the solidification front in a continu
ous casting process of copper tubes to prevent the main failures derived fr
om a lack of control on this front. Specifically, the point is to prevent t
he leaking of liquid copper in the exit zone of the mould, to prevent mandr
el failures or casting detention due to its thermal contraction, and finall
y, to prevent failures in the granular structure of the tubes. (C) 1999 Els
