Unique high temperature, energy efficient ceramic coatings are being used in heat treating and forging furnaces around the globe to reduce the high cost of refractory maintenance, reduce fuel consumption and improve furnace efficiencies as well as product quality. In addition, these coatings also protect metal from oxidation when used at elevated temperatures as well as corrosion in caustic environments. We will show how these specialized ceramic coatings can provide energy savings depending on the fuel being used, the furnace operation, furnace configuration, and production schedule of at least up to 20%. Additionally, we will show that furnace heat up and turn-around times are decreased and how the service life of ceramically coated refractories are extended.
