Module 3: Ladle Metallurgy
  Lecture 26: Degassing Practice

Degassing processes


There are 3 methods of degassing which are in practice

  1. Ladle degassing
  2. Stream degassing
  3. Circulation degassing

All these processes are carried out in ladles.


Ladle degassing

Ladle containing molten steel is placed in a chamber which is then evacuated. After a determined time ladle is removed from the chamber and is teemed for casting. Figure 26.1 shows ladle degassing unit.
