Shandong Sinorefractory New Materials Co.,Ltd manufactures a comprehensive range of high performance Zirconia Tundish Metering Nozzles,
used mainly in the continuous casting of steel billets.
Tundish Nozzles usually comprise a zirconia inner nozzle (often referred to as a "zirconia insert") with a lower grade outer body such as Alumina Bauxite, often be called Outer Alumina Carbon material.
TUNDISH NOZZLE used for the continuous casting of steel.
SNREF Products used in Tundish can be offered to you as follow:
Tundish metering nozzle
Non swirling tundish nozzle
Tundish upper nozzle
Tundish lower nozzle
Tundish slide plate
Quick-exchange tundish nozzle
Ladle shroud
Subentry nozzle/ submerged entry nozzle
Monoblock stopperThis product is suitable for continuous cast tundish open cast steel.
The zirconium insert is made of high-purity zirconia, which is formed by high-pressure molding and sintering at high temperature.
The outer is made of corundum and high-quality aluminum vanadium.
It is formed by high pressure molding and baked at low temperature.
The two are bonded with corundum mud, and the product's corrosion resistance and thermal shock stability have reached the domestic advanced level, which can fully meet the needs of various billet continuous casting.
