    摘要： Method for the continuous casting advantageously, but not only, of long products such as billets or blooms, whereby the solidification of the cast product (16) is completed at a position downstream of the outlet of the mould (13) and whereby the cast product (16) leaving a continuous casting machine (11) curving at a speed of at least 4 mts/min. is transferred into the horizontal segment with at least 12% of the section constituted by the liquid core without being sheared to size, the liquid core being solidified just before the cast product (16) is fed to a temperature-maintaining and pre-heating system and is then fed to a temperature-equalisation and fast-heating system and is fed lastly to a rolling train without any discontinuity and/or interruptions of the process, the preset casting speed bring at least higher than the critical speed of the rollers of the rolling train (18), and there being at least a stage, between the temperature-equalisation and fast heating system, where the core of the cast product (16) is tempered by the propagation of the surface heat, the temperature of the core and the surface of the cast product (16) being made uniform and homogeneous.
    Continuous casting line which is advantageously, but not only, for the casting of long products such as billets or blooms and which comprises at least a continuous casting machine (11), temperature-maintaining and possible pre-heating means (22a, 22b), temperature-equalisation and fast-heating means (19) and a rolling train (18), the components (11, 22a, 22b, 19, 18) being arranged in sequence in line, the cast product (16) extending without a break of continuity from the casting machine (11) to the rolling train (18).
