Sanlong-carborundumsilicon series

uses

　　The Sanlong-carborundumsilicon series refractory materials, as hi-grade products, are manufactured by Professor Jiang Mingxue of our company, who has supported by the key technology surmounting projects of State Eighth-Five-Plans and the Ninth-Five-Plans and after through almost 11 years of scientific technical development and practical applying as well as sustained innovation and perfection. Especially, the Sanlong corundum-zirconium sliding water gap has passed the state-level appraisal and been awarded many items of state or province or ministry-grade scientific technology achievements prizes.

　　 The products have been exported far into many countries and regions of East Europe, North America and Russia etc. The Sanlong corundum abrasion-resistant material used in power plant and ore dressing plant may substitute for hard alloy and will surpass 6 folds of use time than that of hard alloy, being confirmed by users. The Sanlong silicon carbide series ceramic kiln is of excellent properties of hi-intensity and anti-heat-shocking; as a kind of hi-temperature bearing kiln, its service time approaches advanced world level.
