Vacuum Degasser

Depending on the steel grades to be produced, various after treatment methods and process combinations can now-a-days be applied to modern steel making shops. For some grades of steel vacuum treatment has to be given to the steel to achieve strict quality parameters. Various processes have been developed using vacuum.
VACUUM DEGASSING PROCESSES :
Vacuum degassing is practiced in the steel industry for several purposes. They are : -
to remove hydrogen
to improve cleanliness by removing part of the oxygen
to produce steel of low carbon content (
to produce steels to close chemical composition ranges (including deoxidizers), and
to control pouring temperatures, especially for continuous casting operations.
