Remote Cooling of Rolls in Hot Rolling; Applicability to Other Processes
Metals, 2021 A novel method of cooling rolls in hot rolling is proposed. This method uses a combination of solid jet nozzles and specially shaped deflecting vanes. The vanes transform the incoming cylindrical water jet into a flat fan.
