  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. Features: 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. Features: 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 acc...

This makes it to be an ideal choice to molten metals. It's effortless to be machined to custom design with precision and tight tolerance because of its machinability. Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100 °C. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from 1000 degree-furnace and cooling it within short minutes. It still won't break even repeat this test 100 times. Boron Nitride nozzle is often used in metal process for metal atomizing including various precious metal like gold, platinum, silver, etc Customized design of BN nozzle will be available for INNOVACERA
