Ceramic Welding

Ceramic welding is an advanced hot-repair method used for the refurbishment and reinforcement of superstructure refractories in industrial furnaces. In this technique, a specially formulated refractory powder mixture is projected onto the damaged surface together with an oxygen flow. The exothermic reaction at the point of impact melts the powder, which then vitrifies and creates a durable bond with the original refractory. As a result, worn-out areas are rebuilt, the surface is protected, and tightness is restored.

In-Furnace Applications

In-furnace ceramic welding operations are carried out using water-cooled lances, ensuring safe and controlled application. This method allows direct intervention in targeted areas even under high operating temperatures, while maintaining workplace safety and supporting continuous production during the repair process.

Advantages for Operators

Extended furnace lifetime: Ceramic welding quickly and effectively repairs damaged superstructure areas, significantly prolonging the operating life of the furnace.

• Continuous production: By reducing the risk of unplanned furnace shutdown, it supports uninterrupted manufacturing.
• Cost optimization: Delays the need for early shutdowns or major overhauls, generating substantial cost savings.
• Reliability: The weld integrates with the original refractory, providing high durability and long-term protection.
