Container Glass Feeders: Recent Developments In The Choice Of Refractory Materials (In French)

Feeders play a crucial role in the quality of glass. Any defects generated in the feeder zones could well be found in the finished product, since the glass at this stage works at relatively low temperatures and has a low capacity to absorb any flaws. In addition, market demands for quality are constantly on the increase. Defects and flaws which were acceptable in the past are now often the cause for rejecting the glass. Regardless of the design used to channel the glass from the distributor to the machines, and to condition it thermally for forming, the choice of refractories both in glass contact and in the superstructure is increasingly important. This article looks at various types of refractories.
