Multi-shank element (3 or more)
performers in float glass production type W three phase silicon carbide heating elements are comprised of high-purity, high-density, silicon carbide grains that are self bonded through recrystallization at elevated temperatures. Sintering at temperatures in excess of provides a structural density of 2.50 grams per cubic centimeter. Such high structural density results in of maximum strength and minimum porosity, with an extremely slow aging characteristic. For maximum temperature is up to 1500 deg C.
Silicon carbide heating elements designed to be utilized in float baths for the manufacture of soda-lime flat glass for architectural, automotive and solar-glass applications. float glass heating elements have recorded campaign lengths up to 18 years.
3-phase heating elements are available in special glazed quality, to minimize attack by volatiles present in the tin bath. Special grades are available for the production of display glass as well as borosilicate glasses and other special glass formulations
