Remote Cooling of Rolls in Hot Rolling; Applicability to Other Processes

A novel method of cooling rolls in hot rolling is proposed. This uses a combination solid jet nozzles and specially shaped deflecting vanes. The vanes transform the incoming cylindrical water into flat fan. Thereby, coolant can be directed hardly accessible locations whilst maintaining optimal angle impingement. allow for effectively roll surface near gap, which otherwise not possible with classical fan nozzles. impact tangential due to limited room nozzle mounts or supply. developed was laboratory tested. similar efficiency found between vane nozzle. latter however mounted position impossible plant. potential proposed is, therefore, eminent. Apart from rolling, it could exploited other technological processes such as high pressure die casting, machining, turning, stamping, etc.
