The major roles of the Ladle Gate Refractories and Ladle Gate Systems are:
- To adjust the steel flow from ladle to tundish
- To minimize the risk of steel re-oxidation
These roles must be achieved at a minimum overall cost for the producer.
Vesuvius teams combine their respective skills and experience in material selection, refractory design and system inventiveness to offer a wide range of Ladle Slide Gate Refractories and Systems that can answer steel producers needs.
These gate solutions can be combined into a more global solution with Ladle Shroud and Gaskets, Automatic Flow Control, Gas Inerting or Robotic Solutions, all possibly supplied by Vesuvius.
