the monolithic stopper rod, the ladle shroud, and the submerged entry nozzle—are essential refractory materials used in continuous steel casting. They primarily serve to protect the casting process (ladle shroud and submerged entry nozzle) and control the flow of molten steel (stopper rod).
Operators often see cracks and damage in ladle shrouds, long nozzles, and refractory parts. This happens because of a few main reasons: Knowing these reasons helps teams stop corrosion, breaks across the part, and chemical damage. This helps ladle shrouds last longer. Key Takeaways 1. Thermal Shock Temperature Changes When the temperature changes quickly, it puts stress
When you choose ladle shroud from a China factory, there are both risks and opportunities. Some suppliers may not always provide good quality or reliable service.
Introduction A ladle shroud, long nozzle, shrouding pipe, or pouring tube is a highly critical refractory component in continuous steel casting. It is a hermetically closed tube between the tundish and ladle so that molten steel will pass unbroken but be shielded from atmospheric contamination. Steel quality would otherwise be severely degraded by oxidation, turbulence,
In June 2022, the aluminum carbon FZ slagline ladle shroud used on site has a normal service life of 4h, extreme erosion (breakage) of 5h, and steel grades Q235 and Q235B Later, the steel company wanted to use a longer-life aluminum carbon slag line long nozzle, so it experimented with slag lines GZ
