A Complex Approach for Secondary Cooling Improvements Using Sophisticated Spray Nozzle Analyses in Various ArcelorMittal USA Casters

Original language description

ArcelorMittal USA operates various continuous casters that produce a wide spectrum of steel grades. These casters were built in the 1980s or earlier when the knowledge of the effects of specific nozzle designs on the resulting slab surface temperature in the secondary cooling zone was not as sophisticated as today. Today, procedures such as off-line nozzle testing using an impact pressure measurement for spray footprint analysis, heat transfer coefficient (HTC) measurement with realistic casting conditions, and off-line and on-line slab surface temperatures calculations with implementation of directly measured HTCs are the most important steps in the process of analyzing the effect of nozzles used for secondary cooling at ArcelorMittal USA. The results of these types of analyses achieved by close cooperation within R&D, Operations, Quality and Operation Technology departments produce 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.
