Vacuum Degassing of Steel
The height the molten steel drops (i.e. the pouring height) is one of the most important variables impacting the effectiveness of the stream degassing process. In addition to ladle-to-mold degassing, there is another variation referred to as ladle-to ladle-degassing, in which a second ladle is loed inside the vacuum chaer, in place of the mold.
