The roll cooling system is designed to decrease the temperature of the table of work rolls coming from the mil. The rolls are loaded onto the stands in pairs as they are extracted from the mil and properly sized nozzles guarantee the required flow of coolant water on the roll barrel to reach the desired temperature.
Details
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.
