| titleOfInvention | Zirconia water gap and manufacturing method thereof |
| abstract | The invention discloses a zirconia water gap, which comprises a zirconia inner core, wherein a meltable anti-scouring composite material coating is arranged on the inner surface of the inner core. Also disclosed is a method of manufacturing a zirconia nozzle comprising: manufacturing a zirconium oxide inner core; preparing an anti-scouring composite material coating; adding the coating into the zirconia inner core, sealing two ends of the inner core, putting the inner core into a high-speed centrifuge, and performing centrifugal molding; heating to 300 ℃ after molding and drying. The composite material coating is added on the inner surface of the inner core of the high-density zirconia water feeding port, so that the molten steel is prevented from directly contacting the inner surface of the zirconia water feeding port, the composite coating can slowly disappear in 5-10 minutes under the scouring of the molten steel, the preheating time of 5 minutes is strived for the zirconia water feeding port, the occurrence of microcracks is avoided, the high-density zirconia water feeding port without microcracks is very good in anti-corrosion performance, and the service life can be greatly prolonged by 30-50%. |
