ABSTRACT:
Method to shear a strip during the casting step, wherein the casting speed is increased, with respect to a speed of a stationary regime, maintaining the thickness of said cast strip constant to the value corresponding to the speed of a stationary regime, in order to determine the formation of a |liquid core which determines the re-melting of the adjacent skin and the breakage of the strip due to the weight of the part of the strip located under the liquid core.
