The application of this products accomplish the quick exchange of SEN, extends service life of tundish and decreases production cost. The bore of tundish nozzle is sintered zirconia and wholely inlayed , which has better anti-corrosion and anti-erosion property, and extends working duration of tundish and have better cooperation with stoppers. Therefore it can meet different continuous casting levels.
1 .Alumina-graphite seat with perfect anti-thermal shock property.
2.The bore adopts sintered zirconia materials with perfect anti-corrosion and anti-erosion property
3.The end part adopts stablized zirconia product, has better anti-erosion property ,and also perfect for steel flow control.
