High Temperature Fused Silica Quartz Roller is our main product.Fused silica ceramic roller can be used as the key part of the floating glass or steel furnace to bear and transit the glass or steel plate.
Molding methods mainly are grouting and gel injection molding, dry pressing and cold isostatic pressing. We can produce big size of fused silica ceramic roller by these methods.
There are end caps and end shafts, usually made of metal, tightly connected at both ends of ceramic rolls.
Fused Silica Quartz Roller Usage
Fused silica ceramic roller is ideal substitute for graphite rolls and ceramic coating rolls, prevent oxidation and dross build-up, carrying and transmitting glass in glass horizontal tempering furnace and annealing kilns.
