Description

TYPE WDB THREE PHASE SiC elements in float glass production, are comprised of high purity, high density, silicon carbide grains, self bonded through recrystallization at elevated temperatures. Sintering at temperatures in excess of ***0ºC provides a structural density of 2.*0 grams per cubiccentimeter. Such high structural density results in SiC elements of maximum strength and minimum porosity, with an extremely slow aging characteristic.Strength of the SiC elements is further enhanced by insertion of hot zones into oversized cold ends. Enlarged cold ends measure *8mm(1.*0”) in diameter, accommodating hot zones of *9mm (0.*5”) in diameter. Close tolerance sizing helps assure SiC elements fit to conventional roof construction. Leg to leg oncenter spacing is *2mm(2.*5”). Overall element length is **7mm (*5.*7”). Length of hot zone is **5mm (*0.*3”). Height of bridge is *2mm (1.*6”). Cold end length is **0mm (*3.*8”). The support 5.6mm (0.*2”) hole is *4mm (1.*3”) from the top of the cold end.
