  • Ladle for enhanced steel vacuum decarburization
    Patent number: 6461404
    Abstract: A ladle is equipped with properly positioned side and bottom injectors for enhanced steel decarburization in a vacuum tank degasser. To facilitate the circulation of liquid steel in the tank the bottom injectors are positioned in a common segment in order to create a single loop of liquid flow. To enlarge the surface area exposed to vacuum, and to increase the active surface area, supplementary gas flow is provided by side injectors located at the upper sidewall. The active surface area is enhanced by breaking bubbles released from side injectors.
