Method for casting a cast strip in a continuous casting plant, which is equipped with a process computer, with at least one casting machine, wherein the process computer comprises at least one first software which computes in real time and regulates the casting process, wherein the process computer comprises second, additional software which computes more rapidly than in real time so that the computing speed for the second software is thereby greater than for the first software, wherein the second software on the one hand in association with a determined casting length (K; L; M) and on the other hand in dependence on currently obtained process parameters computes from the continuing casting process particularly in the area of the mould and/or from at least one process parameter stored in a databank, which position for an end of the liquid phase of the cast strip in accordance with the determined casting length (K; L; M) along a supporting strip guide of the continuous casting plant was currently present, wherein the second software compares this calculated position of the end of the liquid phase with a target position or a target region for the end of the liquid phase and on the basis thereof continuously computes a casting speed correction value, characterised in that the casting speed correction value calculated by the second software is transferred to the first software, wherein the first software regulates the position of the liquid phase in real time with the help of the casting speed and in that case takes into account the casting speed correction value, which is calculated by the second software, in association with the determined casting length only with a delay which is derived from a spacing on the target position or target region for the end of the liquid phase and the last casting speed set in real time so that a position of the end of the liquid phase of the cast strip in the continuing casting process is constantly present within a predetermined or selected region along the supporting strip guide or the end of the liquid phase of the cast strip is kept in this predetermined or selected region, and the computation of the casting speed correction value is carried out by means of the second software on the basis that the instantaneous target speed is averaged from all positions (K; L; M) along the casting length up to the position of the end of the liquid phase. wherein the second software on the one hand in association with a determined casting length (K; L; M) and on the other hand in dependence on currently obtained process parameters computes from the continuing casting process particularly in the area of the mould and/or from at least one process parameter stored in a databank, which position for an end of the liquid phase of the cast strip in accordance with the determined casting length (K; L; M) along a supporting strip guide of the continuous casting plant was currently present, wherein the second software compares this calculated position of the end of the liquid phase with a target position or a target region for the end of the liquid phase and on the basis thereof continuously computes a casting speed correction value, characterised in that the casting speed correction value calculated by the second software is transferred to the first software, wherein the first software regulates the position of the liquid phase in real time with the help of the casting speed and in that case takes into account the casting speed correction value, which is calculated by the second software, in association with the determined casting length only with a delay which is derived from a spacing on the target position or target region for the end of the liquid phase and the last casting speed set in real time so that a position of the end of the liquid phase of the cast strip in the continuing casting process is constantly present within a predetermined or selected region along the supporting strip guide or the end of the liquid phase of the cast strip is kept in this predetermined or selected region, and the computation of the casting speed correction value is carried out by means of the second software on the basis that the instantaneous target speed is averaged from all positions (K; L; M) along the casting length up to the position of the end of the liquid phase.
