Elimination or Minimization of Oscillation Marks: A Path To Improved Cast Surface Quality

Elimination or Minimization of Oscillation Marks: A Path To Improved Cast Surface Quality

Date: December 17, 2007
Creator: Cramb, Dr. Alan W.
Description: Oscillation marks are the most recognizable feature of continuous casting and can be related to the subsurface defects that can be found on product rolled from continuous cast slabs. The purpose of this work was to develop strategies that can be used on industrial continuous casters to reduce oscillation mark depth and, in particular, to minimize the formation of hook type defects that are prevalent on ultra low carbon grades. The major focus of the work was on developing a technique to allow heat transfer in the meniscus region of the continuous caster to be measured and the effect of mold slag chemistry and chrystallization to be documented. A new experimental technique was developed that allowed the effect of mold flux chemistry and chrystallization on the radiation heat transfer rate to be measured dynamically.
