Refractory 5.4g/Cm3 95% ZrO2 Upper Nozzle For Steel Continuous Casting
Working hours of the Upper Nozzle
For the working hours of our zirconia insert used in the tundish upper nozzle, based on the different steel types filled in tundish, different casting times of the tundish, different qualities of the tundish nozzle, the working times of the tundish nozzle are different. Fangming NewM are producing the requested the zirconia upper nozzle, lower nozzle, quick-changable nozzle, metering nozzles according to the clients' demand for the shape and sized, the working times has reached 20-30 hours continuously.
Production Process
Our zirconia insert for the tundish upper nozzle is taking the world's advance automatic production equipment and technology, and take the high quality of the zirconia grain and powder, adding other additives, through the mixing, drying, inspecting, pressing, inspecting,drying, sintering,inspecting, etc. standard and system process, then produce the exact size, high quality, longer-working times of the zirconia insert for tundish upper nozzle.
Upper Nozzle Chemical composition and Physical Properties
| Model | Chemical Composition | Physical Properties | ||||
| ZrO2+HfO2 (%) | Al2O3 (%) | SiO2 (%) | MgO (%) | Bulk Density (g/cm3) | Apparent Porosity (%) | |
| FMXC-N03 | ≥95 | ≤0.2 | ≤0.4 | ≤2.9 | ≥5.40 | ≤8.0 |
Bonded Style
Our zirconia lower nozzle is usually embedded in the alumina or corundum and graphite body with the refratcory motar. Also export to oversea countries, and the buyer press the zirconia insert into the body directly.

Company Introduction
Setup in Sep.,2015,Fangming NewM. is one high-new technology producing enterprise of the high purity and the ultra-high temperature new type of thecomposite nano-ceramic materials and products based on the raw material of the zirconia, and the one manufacturer of urgently much needed to breakthrough key technologies in the new materials category advocated and developed by the state in the 2025 planning catalogue, of the rare oxide composite new materials of the super high temperature structural ceramics, which are applied in the extreme environments.
Up to now, we have gained the ISO9001:2015 Quality Management System Certificate, ISO14001:2015 Environment Management System Certificate, OHSAS18001:2007 occupational Health&Safety Management System ,ISO50001:2011 Energy Management System Certificate, etc. Certificates.Meantime, we have owned the 8 related invention patents and utility model patents.
Large size, super special shaped super high temp. zirconia ceramics, we will offer the comprehensive and integrated super high temperature, strong crushing resistance, strong erosion resistance application condition solutions.
Other series Products
For the long working life, high efficiency products what we produce are tundish zirconia nozzle insert,EAF,ladle and converter slag-stopping embedded the zirconia slide gate, zirconia ring, super-long-working-life of zirconia atomizing nozzle, artificial crystal (Sapphire, laser sapphire, etc.) growing equipment rare-earth composite oxide SS ceramic thermal field, etc.series products. The product's quality is equal to, even higher than the ones made in EU, USA, and favorable price, obviously working effects.
