A complex approach for secondary cooling improvements using sophisticated spray nozzle analyses in various arcelormittal USA Casters

Popis výsledku v původním jazyce

ArcelorMittal USA operates various continuous casters which produce a wide spectrum of steel grades. These casters were built in the 1980's or earlier when the knowledge of the effects of specific nozzle designs on the resulting slab surface temperature in the secondary cooling zone were not as sophisticated as today. Today procedures such as offline nozzle testing using an impact pressure measurement for spray footprint analysis, heat transfer coefficient (HTC) measurement with realistic casting conditions, offline and online slab surface temperatures calculations with implementation of directly measured HTC's are the most important steps in the process of analyzing the effect of nozzles used for secondary cooling in ArcelorMittal USA. The results of these types of analyses achieved by close cooperation within R&D, Operations, Quality and Operation Technology departments produces slabs with improved surface quality. This type of analysis can determine which sprays are performing poorly and lead to significant improvements in slab quality. Examples of this complex approach for Indiana Harbor and Burns Harbor casters will be discussed to show improvements in secondary cooling efficiency and slab quality. © 2017 by AIST.
