roll cooling nozzles on the spray header is essential for optimal roll cooling. Flat jets are the preferred spray pattern for roll cooling, therefore only a self aligning nozzle design provides the operation safety required in a modern rolling mill. All flat jet nozzles of the Lechler series 6E4 and 6E5 come with an automatic self aligning

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.

For large applications, dimpled jackets provide a higher pressure drop at a lower price point than conventional jacket designs. Dimpled jackets allow for large heating and cooling transfer areas at lower pressures (up to 300 psi). These jackets feature a layer of thingauge metal that is plug or spot welded to the vessel shell in a regular pattern.
