  • What is the lifetime of refractory materials?

    Refractory materials will fill their lifespan even if they are not subject to an accident. Once this happens, removal of the refractory material and recycling becomes mandatory. Eradication of wasted materials is possible, although recycling process will prevent harm to the environment and help reduce the cost of reconstruction.
