Bi-Ceramic Tundish nozzle with the zirconia insert and alumina/corundum together-fangming ceramics

Products Features:

Bi-Ceramic Tundish nozzle with the zirconia insert and alumina/corundum together-fangming ceramics are supplying, the zirconia insert has the high purity and high density, the excellent 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, the alumina bonding with the refractory motar, and corundum material casting body, we take the high quality of the alumina/conrundum powder and grain, with the special high quality of the bonding material, produced the 2.5-2.6g/cm3 density (alumina), 3.1-3.2g/cm3 (corundum body) of the composite nozzle, and increase the whole working life of the complete nozzle.

Working life of the Zirconia Metering Nozzle Insert

For the working life of compiste nozzle embedded Zirconia Nozzle insert into it, used in the tundish, based on the different smelting steel types in tundish, different casting times of the furnace, the working lifes are different. Fangming NewM can produce the requested the zirconia metering nozzles according to the clients' demand for the shape and sized, the normal working life can reached over 40hours continuously, even higher.

Production Process

Bi-Ceramic Tundish nozzle with the zirconia insert and alumina/corundum together-fangming ceramics 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.
