GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD …
Hot mills generally need more cooling and it is an advantage to have exit sprays as well as entry sprays. However, the exit sprays have more effect because the roll surface temperature is higher on the exit side. As a rule of thumb, the exit side cooling flow rate should be in the range of 2/3 of the total mill flow rate –figure 5.
