Hot Refractory Maintenance Services

Cetek offers a range of Refractory Maintenance Services for furnaces used in steelmaking. These services can be performed at operating temperature, minimizing the need for down time and production losses.

Ceramic Welding: Cetek’s Ceramic Welding repair and maintenance program allows steel producers to repair furnace linings to the original integrity of the refractory located in high wear areas without shutdown. Refractory restoration can be achieved at operating temperature, in areas such as Reheat furnaces and Ladles. Any castable refractory type can be matched with a compatible Ceramic Welding material. The properties of the weld repair are typically equal to the original refractory.

Gunning: Cetek supplies a range of gunning materials for numerous steel applications. The materials are super-duty mullite-based which use a hydraulic cement bonding mechanism to provide strong, durable gunned repairs. The material is applied with consistency by trained technicians utilizing proven techniques resulting in a dense, smooth repair with documented longevity and durability. The process achieves superior mixing of water and materials prior to the point of contact with the base refractory.
