The alumina carbon ladle shroud consists of two parts: the body and the slag line. The main components of the body are Al2O3 and C+SiC. The main components of slag line are ZrO2+C or MgO+C. The alumina carbon ladle shroud has the characteristics of purifying molten steel, resisting corrosion from molten steel, and preventing oxidation of molten steel.
The alumina carbon ladle shroud is divided into two parts: the main body and the slag line.
The main raw materials used for the body are corundum, graphite, and silicon carbide.
The main raw materials used in the slag line are zirconia sand, graphite, and silicon carbide, with resin as the binder. After various raw materials are mixed and granulated, they are formed on the static press machine. After drying, it is fired in a non oxidizing kiln. After processing and non-destructive testing, the finished product is obtained by spraying an anti-oxidation coating.
The alumina carbon ladle shroud is installed between the continuous casting intermediate ladle and the crystallizer to prevent oxidation and splashing of molten steel, adjust the injection rate of molten steel in the crystallizer, and prevent the mixing of casting powder and non-metallic inclusions into the casting billet.
The alumina carbon ladle shroud has strong adaptability to different types of steel, especially suitable for casting steel with high manganese content. It has good resistance to steel and slag erosion.
It can purify molten steel, resist molten steel erosion, resist oxidation, and has a long service life.
Main features of the alumina carbon ladle shroud
1) Purification of molten steel to prevent impurities from entering during the casting process.
2) Resistant to molten steel scouring and high temperature.
3) Antioxidant and resistant to molten steel erosion.
4) Suitable for casting multiple molten steels.
Main application
The alumina carbon ladle shroud is mainly used for casting various types of molten steel in the continuous casting process.
