General information:


After hot rolling or between the rolling passes, the strip temperature and the material properties are adjusted by cooling sections. The task of these devices is to cool down the strip from Tin to Tout, eventually with additional requirements regarding cooling rate, and minimum surface temperatures or including self tempering of the strip.
Process models can be used to predict the cooling of the material.
Inverse process models can be used to predict set-values for the cooling section, minimum cost production parameters or demands to cooling technology for the realization of specific cooling rates and temperature guideways leading to specific material properties.

Cooling technologies:

Spray water cooling with a spatially varying water impact density VS [kg/(m2s)] implies a heat transfer coefficient h(VS,T), as shown below acting at the material surface.

Other technologies (e.g. direct quenching) can be described in a similar way.
