1. A method comprising:
defining a length section (Lx) of a metal product;
guiding a metal strip through a combined casting and rolling system; and
tracking the defined length section of the metal product during its guidance through the combined casting and rolling system;
predefining a threshold value for the performance of a severing or forming device;
calculating, with a neural network, an actual value pIst for an indicator p of the metal product in the defined length section, wherein the indicator p represents resistance of the metal product to severing or forming processes;
deciding, with the neural network, whether a severing device or a forming device of the combined casting and rolling system varies parameters in calculating the actual value pIst for the indicator p;
comparing the calculated actual value pIst of the indicator p to the predefined threshold value for the indicator p; and
severing or forming the metal product in the defined length section only when the actual value pIst of the indicator p is less than the threshold value.
