High Quality of tundish upper nozzle with alumina body and zirconia insert- working for over 30 hours

Products Features:

High Quality of tundish upper nozzle with alumina body and zirconia insert we 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 body, we take the high quality of the alumina powder and grain, with the special high quality of the production technology, produced the 2.5-2.6g/cm3 density 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 Metering Nozzle 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 30hours continuously, even higher.

Production Process

Our supplied the compisite nozzle with 5.1g/cm3 Metering Nozzle Insert and Al2O3 Body used in tundish 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.

Zhengzhou Fangming High Temperature Ceramic New Material Co., Ltd. Lies in Xinmi City, Henan, China. It covers over 20000 sm2.

Setup in Sep. 2015, Fangming NewM is one High-New Technology Enterprise, manufacturing the high-purity and ultra-high-temp. new type of composite nano-ceramic materials and products as the zirconia basic material, and the one of the urgently to be solved and breakthrough key technologies in the new materials category advocated and developed by the state in the 2025 planning catalogue, the one of the rare composite new materials of the super high-temp. structural ceramics, applied in the extreme environments. We has obtained the ISO 9001:2015 quality management, ISO 14001:2015 environmental management and OHSAS 18001:2007 occupational health and safety management system, the energy efficiency management system, etc. series qualifications, and has owned eight patents.

Since setup, our company is devoted to the R&D, creation of the new type of composite nano-ceramic materials and products. Fangming NewM mainly produce: 1). ZrO2 Nozzle, slide plate, ZrO2 Ring, Insert, applied as flow control function in metallurgy at high-temp. State, 2). ZrO2 atomizing nozzle in the amorphous alloy powders, 3).Rare-Earth Oxide Composite SS ceramic thermal field in artificial crystal (Sapphire, laser gem, etc.) grower, 4).Pre-sintered ZrO2 parison, base plate for metal sputtering target, 5). High density ZrO2 ceramic lip brick in ultra thin electronic glass , sintering gasket in electronic device. 6). Device in hot compression equipment of 3D glass, etc. The quality of products we are producing is the same, even better than the one produced by the other producers in the same industry from USA, European countries.

Taking the modernized automatic controlled equipment, persistently carry out the digitized, standardized production and management processes, the advanced ERP and IMES management system in our country, the product’s quality and overall performance has reached even exceeded to the level of the same industry in the world.
