Claim 1:
2. The method as in claim 1, wherein said crystallizer (12) has a crystallizer length (LM), wherein said mold (11) comprises a plurality of guide rollers (25) disposed at an exit end of the crystallizer (12) and that extend for a guide length (LG) along a casting line (Z), and wherein said containing length (LC) is:
equal to zero if L<LM+LG
equal to L−(LM+LG) if L>LM+LG
where:
LM: is the length of the crystallizer (12);
LG: is the guide length covered by the guide rollers (25);
L is determined so as to satisfy the following equation:, L
