Refractory orifice rings, tubes, spouts, plungers for glass furnace gob feeder machines

Zircon 333 Material provides the excellent corrosion resistance to glass melts and have been proved to be safe to be installed in glass feeder channels and as expendable shapes like tubes,spouts, plungers,etc..

Besides Zircon 333, we could also supply other options for glass feeder solutions according to different glass compositions and furnace condtions, such as sillimanite, fused silica, 93% Al2O3 corundum, and also fused cast AZS materials,etc...
