Free preheating ladle shroud
Free preheating ladle shroud is a effective protection channel for steel liquid from ladle to tundish. It has the function of stability steel liquid , anti oxidation of steel liquid and liquid splash . argon is blowing by seat position to reduce nitration suction of steel liquid .we made this free preheating ladle shroud has the strong points of no-cracking , steel liquid flashing resistance, and high erosion resistance.We developed special shape nozzle casting under the liquid level in order to avoid splashing and oxidation.
We make different types of ladle shrouds with customised argon sealing and bell designs to ensure complete protection of the steel stream from splashing and oxidation as it flows from the steel ladle to the tundish. As different steel products have different specifications, we have developed more than ten patterns to suit different designs of steel ladle and tundish required by our customers. For added durability and protection, we apply specialised materials at the seat which has a particularly high potential for oxidation. A special mixture of materials is put into the liner to prevent gouging. For added measure a mixture of zirconia or magnesia is used for the slagline to protect our ladle shrouds from chemical corrosion caused by tundish powder, ensuring the integrity of the steel flow.
Details:
Depending upon the concasting condition, we provide ladle shrouds of Alumina Graphite or Alumina Zirconia Graphite. The products have the following characteristics.
1) Prebaking unnecessary
With the functional gradient structure, our ladle shrouds are characterized by high thermal shock resistance and can be applied to the con-casting process directly from the ambient temperature, without preheating.
2) Long service life
Specially designed slag line composition for customer casting conditions guarantee our ladle shrouds with the properties of high erosion resistance long nozzle main specification item CLT-ACLT-Bchemical parameterAl2O3≥5045C+SiC≥2525C.C.S.Mpa≥2220M.O.R.Mpa≥65App.Porosity %≤1718g/cm3≥2.42.35Resistance to thermal shocktimes5
