Mathematical Modelling Of Roll Cooling And Roll …

the influence of the cooling system on roll performance, a good understanding of the thermal aspects of roll cooling is essential. In hot rolling, wear of the work roll takes place mainly because of: (i) abrasion of the roll surface due to contact with the strip, and in a four high mill, due to contact with the back-up roll also

Mill Coolant System Design

A simple system like this requires specification of coolant flow to provide proper flushing and cooling of each production process, with the total flow requirement being equal to the sum of the individual requirements (see Figure 1). This calculation is important because the components used in coolant purification all are flow rate-specified.
