Magnesium Stabilized Zirconia (MgO-ZrO2) Ceramic Nozzles

1. MgO-ZrO2 Ceramic Metering Nozzles (lnserts)

They are mainly used in steel making continuous casting ladles, converter tundishes, and converter taphole slag retaining mechanisms.

Magnesium Stabilized Zirconia Ceramic Nozzles


  • Good erosion resistance, corrosion resistance
  • Thermal shock stability
  • The service time is generally 50 hours, which solves problems such as clogging, cracking and diameter expansion.

Related general products:

  • Continuous casting tundish upper nozzle
  • Tundish quick change nozzle
  • Fixed diameter nozzle for continuous casting.

2. MgO-ZrO2 Ceramic Atomizing Nozzles

They are mainly used in the powder metallurgy industry, the smelting of ferrous and non-ferrous metal powders, such as nickel-based alloy powders, copper powders, stainless steel powders, iron powders and other super alloy powders.


  • Higher density,
  • Excellent resistance to high temperature corrosion,
  • Resistance to erosion by metallic liquids
  • Thermal shock performance.

Different stabilizer materials and particle sizes are used according to different requirements. The nozzles of various types and sizes can be customized individually according to different using condition and requirements.
