    Abstract: A computer determines a subsequent state of a steel volume, based on an instantaneous initial state of said steel volume and at least one volumetric surface, the temporary influence quantities acting on said steel volume, by resolution of an equation of thermal condition and phase change. The states include for at least one volumetric element of the steel volume, a local distribution in concentration of a alloy element mobile in the steel, the local proportions of the modeled phases of the steel and a quantity describing a local energy content of the steel. The phases include austenite and another phase, generally, ferrite or cementite. In the context of the change equation, the concentration levels of the mobile alloy element, which are located on either side of the phase boundary, between the austenite and the other phase are determined by resolution of a Stephan problem.

    Abstract: The invention relates to a method for rolling a metal strip (6) in a reverse rolling mill (1) with a coiler located upstream and a coiler located downstream (4,5). The metal strip is wound off the upstream coiler (4) with a strip thickness (d) and at a strip temperature (T) above a set temperature (T*). It is then passed through the reverse rolling mill (1) with a first draught of at most 5% and at a speed (v) before being wound up by the downstream coiler (5). The speed (v) at which the strip is passed through the rolling mill is selected with the aim of ensuring that the strip has reached the set temperature (T*) by the time it is wound up. The strip is then wound off the downstream coiler (5), passed through the reverse rolling mill (1) with a second draught of at least 10% and wound up by the upstream coiler (4).
