Primary forming

  Elongation of inclusions during hot rolling     5 of 6
 
Inclusions can be divided into 2 broad classes:
  1. Non-deformable inclusions - such inclusions are hard at rolling temperatures and maintain their original shape as the steel is deformed.
  2. Deformable inclusions - such species are soft at steel rolling temperatures and deform and elongate as the steel is rolled.

Have a go!The following animation shows how MnS inclusions in a steel are elongated during hot rolling of plate. Start the animation to see how the inclusions change shape during rolling:
