Method and continuous casting line 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.

[ We claim:] [1.] Method for continuous casting, whereby solidification of a cast product is completed at a position downstream of an outlet of a mould, the method comprising:transferring the cast product from a curved continuous casting machine at a speed of at least 4 mts/min. into a horizontal segment with at least 12% of a section of the cast product having a liquid core without being sheared to size; completely solidifying the liquid core just before introducing the cast product into a temperature-maintaining and pre-heating system; then feeding the cast product to a temperature-equalisation and fast-heating system; then tempering the core of the cast product by propagation of its surface heat to make a temperature of the core and the surface of the cast product uniform and homogeneous; and then feeding the cast product to a rolling train without any discontinuity and/or interruptions of the process; wherein a preset casting speed is controlled to a speed at least greater than a critical speed of rollers of the rolling train.
