  Study of the Clogging Phenomenon of Submerged Nozzles in Continuous Casting
  Author(s): Florian Huber*, Bruno Schachner, Jessica Zofia Gottsberger, Peter Benedikt and Andreas Florian Zierer
  
  The continuous casting nozzle, which guides and protects the flow of liquid steel, undergoes a progressive reduction in its internal diameter following the accumulation on the internal wall of non-metallic inclusions. This narrowing of the channel is due to a mechanical attachment (non-metallic inclusions) which results from the turbulent regime of the flow of the liquid steel. This phenomenon is very often associated with the casting of low carbon steels deoxidized exclusively with aluminum. Clogging generally leads to a slowing down of the casting speed and, in severe cases, to the total stoppage of the installation and consequently to the appearance in the slab of the defect called resumption of casting or belt. The aim of this work is to determine the nature of the deposit and the blocking mechanism of the pouring nozzles. For that, a chemical analysis as well as tests concerning .. View More»
