May 15, 2001 · Tank volume is based on flow, cooling requirements, and space constraints, with a starting point minimum of five times the flow capacity the pump. If one central tank is used to feed multiple mills, then a smaller catch tank with its own pumping mechanism must be maintained at each mill.
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
In summary, in most mills the primary surface to target is the work roll. Which side of the mill should one be cooling? The determination of which side of the mill to cool depends upon the overall mill design and cooling strategy. In the typical hot mill, cooling is generally done on both sides for several reasons.
Cooling Rolls. Roll Technology manufactures heat transfer rolls that provide temperature control by circulating cool fluid through coils under the outer shell of the roll. The fluid essentially cools the rolls to the desired temperature for the application. There are different designs and configurations of the spirals within the rolls that can be critical to optimizing the performance of the .
