Inclusions in continuous casting of steel

WebIn continuous casting, it is common to close single or multiple submerged nozzles of multi-strands tundish to adapt to production rhythm due to insufficient liquid steel or equipment failure. However, the closure of the nozzle will change the flow field in the tundish and further affect the removal efficiency of inclusions in the tundish. For this reason, based on … http://ccc.illinois.edu/PDF%20Files/Publications/2024_Papers/20_TMS_CHO-SM%20Multiphase-Flow-Related%20Defects%20reprint%20post.pdf
