High-temperature, energy efficient ceramic coatings are being used in heat treating and forging furnaces around the globe to rein in the high cost of refractory maintenance, reduce fuel consumption, and improve furnace efficiencies as well as product quality. These coatings also protect metal from high-temperature oxidation and corrosion. This paper shows how specialized ceramic coatings can provide an energy savings of up to 20% in industrial furnaces while reducing heat-up and turn-around times and extending refractory service life.
