The aim of this project is to design, build and test, in the normal operating conditions of the hot strip mill, a new short cooling equipment placed between the roughing and the finishing mill, in order to cool, in a very fast and controllable way, the bar coming out of the roughing mill. As far as the products are concerned, the effect of the bar cooling strategy will be assessed for different steel grades. Laboratory trials will be conducted in parallel to the industrial trials. With regard to the process, the following aspects will be analysed, among others: cooling rate, homogeneity, possibility of reduction of though thickness heterogeneity, efficiency of the descaler after bar cooling.
