Tungsten Iridium Nozzle, W-Ir Nozzle, tungsten nozzle for RCF ceramic fiber outflowing production

Tungsten Iridium(W-Ir) Nozzle is important part for thermal insulation ceramics wool and fiber(RCF)blanket outflowing production

Tungsten Iridium(W-Ir) Nozzle is an very important key part for thermal insulation ceramics wool and fiber(RCF)blanket outflowing production

Tungsten-Iridium nozzle and Mo plate or Rod electrode are going with wide application in Refractory thermal insulation Ceramic or Glass, fiber and Wool products manufacturing.

 

Tungsten Iridium Nozzle——for RCF outflowing manufacturing

W-Ir Nozzle for thermal insulation ceramics wool and Refractory ceramic fiber (RCF) outflowing production

Tungsten-Iridium nozzle( W-Ir nozzle) and Mo plate or Rod electrode are going with wide application in Refractory thermal insulation Ceramic or Glass, fiber and Wool products manufacturing.    

W-Ir Nozzle is very important key parts inside two kinds of processing ways which are always used in application for your high quality refractory ceramics fiber production.

 

RCFs are either blown or spun from molten clay (kaolin), or, molten alumina and silica mixtures (roughly 50% each). The diameters of fibers produced are usually between 1-3 microns(µm).

We have best manufacturing technology to provide the precious metal Iridium insert which ensure best anti-erosion property and accurate outflow ability to protect high temperature outflowing flushing out. the Ir insert perfectly fixed into the nozzle body made of tungsten, the tungsten nozzle with Ir insert protects the ceramics melting furnaces undergoing for a longer life time in high melting temperature above 20000C.
