Refractory For Glass ProductsFeeder Expendables System
Fused Silica refractories have excellent thermal shock resistance and are being used for hot repair of silica roof. Silica patching mass provides complete sealing of silica roof by developing ceramic bond. The sealing of roof prevents further soda deposition and corrosion of refractories by preventing escape of hot gases from the roof.

Molding and Production Details for Silica Refractory
Use silica ore to make silica refractory bricks.There is more SiO2 content contained in the silica ore that results the higher refractoriness. The most harmful impurities are Al2O3 K2O Na2O and so on which reduce the refractoriness of refractory products badly. Silica bricks are manufactured with silica ore that contains more than 96 SiO2 content as the raw material by adding mineralizer

Proper practices for optimizing silica refractory campaign
Jul 01 1998 · The recommended width of a sidewall ramming foot is 66-75 of the sidewall thickness. A ramming foot that is too wide won t fit easily between the form and sidewall. Thus the potential exists to destroy the slip plane material while ramming due to the tight fit between the form and slip plane.
