Technical article on "Tweels in sodium silicate glass chemistry"

Even if float technology has been developed and explored in details, the requirement of new and more aggressive glasses is incremental to the expected length of float sequences. The extension of the furnace life through dedicated chemistries and long casting sequences is pushing the working environment to more extreme service conditions. Glass flow control remains a strong demand for quality solution, and should be considered with attention in the global scope of the refractory selection. Tweels as flat arches and joints have to be determined in the light of the glassmaker experience and glass requirement...Read more
