Fused Silica Ceramic Rollers
Made from a material composition that is 99,8% SiO2, our Fused Silica rollers are the right choice for use in a variety of furnaces.
Featuring very low thermal expansion and excellent thermal shock resistance, our rollers made from this material can be used continuously at temperatures up to 1000 °C.
Due to their excellent mechanical properties and their special surface quality, our fused silica rollers are mainly used in a variety of annealing kilns and glass tempering furnaces.
Among other things, these kilns produce safety glass for architectural or automotive use. As an alternative, we also offer our Fused Silica rollers with metal cap in a variety of designs. Special fabrications are also possible at any time.
Hollow rollers, solid rollers, metal caps, grooved rollers and other special varieties.
Our Fused Silica material is also featured in a range of other products such as crucibles for high-frequency melting and those that need to withstand high thermal shock as well as riser tubes for continuous casting.
