The work for PJSC "Severstal" – "Processing facility. Casting & rolling mill-2. Overall modernization assessment of interstand cooling and roll cooling system" successfully completed by SE "UkrRTC "Energostal".
The existing system does not provide an optimal operating temperature for the rolls during thin stripes (1.5-2 mm) rolling & does not permit to take full advantage of speed capabilities of finishing stands group during heavy stripes (more than 6 mm) rolling. It was found during roll cooling system and interstand cooling system of finishing stands survey of rolling mill 2000 at PJSC “Severstal”.
Several upgrading options of interstand cooling (IC) & rolls cooling system (SCR), including the “anti-slabbing” system application in the first stands of finishing mill group developed by SE "UkrRTC "Energostal" specialists during the work progress. Technical features of the cooling manifolds of rolls and finishing stands as well as approximate workload of IC & SCR systems reconstruction are also specified.
The technical solutions implementation developed by SE "UkrRTC "Energostal" will permit PJSC "Severstal" to advance the cooling system efficiency, improve the mill's performance, reduce the rolls consumption and expand the brand range of products as well.
