Refractory Coatings

Ravi Thermal Engineers offers Refractory Coatings, Enecoat. This is a high emissivity refractory coating for furnaces and kilns to increase production, reduce maintenance cost and improve quality. This is a high emissivity coating based on silicon carbide which, when applied and annealed correctly has a long life at temperatures up to 1350°C. This works by raising the surface emissivity of the walls and roof in practically all types of furnace or kiln. Heat is more readily absorbed by a high emissivity surface. The result is an increase in wall temperature for the same furnace radiation (control) temperature. Having achieved a higher temperature, the Enecoat surface is then better able to re-radiate the thermal energy than an uncoated surface. This coating also provides a strong, hard, protective surface for the furnace lining which is especially beneficial for ceramic fibre. It may fill in small cracks and fissures and in many cases, can lengthen the life of the refractory behind it.
