With the increasing demand for steel strips in the market, its performance is required to be higher and higher. The laminar cooling process (LCP) is an important procedure in hot steel strip rolling, which is used to cool the steel strip from an initial temperature of roughly 800950 ° C down to a coiling temperature (CT) of roughly 550700 ° C [1,2].

The hot rolling strip production line shown in Fig. 2 that produced the experimental data consists of six 4high stand finishing rolling mills. For the 4high mill shown in Fig. 3, specifically a HCW mill, the rolls are called backup rolls, which are the rolls at the top controlled by a hydraulic cylinder and the work roll, which is the roll in touch with the steel strip.

In the cold rolling of flat steel strips, electric energy consumption is one of the highest expenses. The tandem cold rolling mill (TCM) studied in this paper, composed of four stands, has a total installed electrical power of MW. Such highpower requirements rest in the fact that steel presents a high resistance to plastic deformation.

Fig 3 Rolling of thick plate in a plate mill. Prediction of stresses and rollseparating force Once the spread (the boundary of the deformation zone) has been calculated, this information can be used to predict the stresses and the rollseparating force. The computerized procedure used here is in principle the same as the method described for predicting the stresses in strip rolling.
