Repairing Material
Various materials are available for the repair of a furnace inner lining, runner, tap hole, and ladle of a
blast furnace. They can exhibit a stable workability and durability throughout the room to hot temperature
condition. Those are used as easy repair materials.

The “HOTTCAST” series are new repair materials developed for the repair in the hot atmosphere. They
are superior repair materials that have easy installation, short repair, high erosion resistance, and high
adhesiveness. Those can be achieved by the self work process of softening, flowing, filling, hardening,
and carbonizing.
