Refractory Metering Zirconia Lower Nozzle Tundish Ladle Brick
Products Features:
Zirconia Lower nozzle is widely used in the tundish we are producing has the high purity and high density, strong the chemical stability at high temp. state, high strength, excellent crushing resistance, erosion of the steel liquid and slag resistance, strong thermal shock stabilities, super low speed of the diameter enlargement of the nozzle, extremely increased the working life of the nozzle.
Production Process
Zirconia Lower nozzle used in the tundish we produced is taking the world's advance automatic production equipment and technology, and taking the high quality of the zirconia grain and powder, adding other additives, through the mixing, drying, inspecting, pressing, inspecting,drying, sintering,inspecting, etc. standard andsystem process, then produce the exact size, high quality,longer-working life of the zirconia lower nozzle in tundish.
Chemical composition and Physical Properties
| Model | Chemical Composition | Physical Properties |
| ZrO2+HfO2 (%) | Al2O3 (%) | SiO2 (%) | MgO (%) | Bulk Density (g/cm3) | Apparent Porosity (%) |
| FMXC-N02 | ≥95 | ≤0.2 | ≤0.4 | ≤2.9 | 5.40-5.50 | ≤9.0 |
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.
Size Tolerance:
Middle Hole Diamter:+-0.2mm, other sizes: +-0.5mm.
Packing:
66pcs/carton, 30cartons/wooden box with fumigation treatment.
Exported Countries
India, Pakistan, Iran, Thailand, Turkey, Peru, USA, etc.
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.
