Internal Cooling Hot Design Work Roll Mill

  • GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD …

    °C The optimum average work roll temperature should be in the range of approximately 50 – 70 °C In addition, it is recommended to cool down the surface of the strip just after the exit of the previous stand This so-called “skin cooling” our “anti-peeling spray” will further help to reduce work roll peeling
