PN series of metering nozzles adopt mosaic pattern - the zirconia’s inner core and alumina sleeve including typical nozzle and fast-changeable nozzle. Both feature high refractoriness, low expansion superior resistance to erosion/corrosion and thermal cycling, etc.
|
|
PN nozzles with fast-change system could be replaced easily to ensure consistent steel flow. They have been widely used in long-life tundish system in many I&S works at home and abroad, demonstrating excellent application results.
