Glass tempering furnace roller bricks

Ceramic fibre roller insulation bricks are widely used in glass tempering furnaces for their excellent thermal insulation properties. These bricks are designed to be installed on the roller conveyor system which transports the glass through the furnace. By using these bricks, the furnace can maintain a consistent temperature throughout the process, ensuring that the glass is tempered evenly.
