Rouleaux céramiques pour fours à base d'oxydes renforcés par un élément de renforcement à haut module d'élasticité à chaud.

摘要

The invention relates to a composite roller for a roller oven comprising an external hollow roller (1) made of refractory material based on oxide and a reinforcement element (2) made of refractory material having a high hot elasticity modulus and arranged inside the external roller, the larger dimension of the cross-section of the reinforcement element being slightly smaller than the inside diameter of the external roller. Utilisation particularly in ovens for baking ceramic tiles.
