We provide products and services to help optimize your roll cooling process. Spray pattern and header placement analysis in roll stand and around rolls helps optimize cooling effectiveness. Roll cooling headers ensure uniform cooling of entire roll. Nozzles provide efficient cooling and proper alignment.
roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the
Transfer bar cooling system installed at the hot strip mill of Tata Steel´s Port Talbot [2]. Whereas transfer bar cooling is installed on HSM’s [1,2], induction heating is more frequently used for mini mills, that is, combined casting hot rolling lines [3, 4]. Transfer bar cooling is installed just after the roughening mill.
That ensures excellent strip surface quality and longerlasting work rolls under the required roughness conditions. The brushes oscillate across the work roll barrel and guarantee uniform cleaning of the roll surface. Due to a special lowvibration design, our work roll brushes achieve an excellent cleaning effect.

The selective roll cooling systems are extremely lowmaintenance and have proven themselves for decades under the toughest conditions in the world market. operated valves operate virtually maintenancefree over millions of switching cycles thanks to their sealfree design. Cooling systems for new rolling mills are developed together with
Strippers and Wipers for Hot Strip Mills. Work Roll cooling is a vital aspect of steel coil production within the Hot Strip Mill. Large volumes of water and coolant are sprayed onto the rolls so that they do not overheat, crack, and deform due to the extreme temperatures involved in the process. While water is an absolute necessity in order to

Flat Rolling Simulation and Reduction of Local Buckles in Cold Rolling1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 7.17 Reduction of Local Buckles. Even though the cold mill itself may cause local buckles, the majority of the local buckles are caused by the feed stock from the hot mill (Melfo et al., 2006). Therefore, proper
