Application of high emissivity coating in foundry aluminium melting furnaces

Energy efficiency of foundry furnaces for aluminium melting is much lower than in most other furnace aggregates, especially because of low emissivity of conventional refractory at operating furnace temperatures as well as low aluminium emissivity and low heat conductivity of molten aluminium. In this paper the application of high emissivity coating in foundry aluminium melting furnaces in order to intensify the heat transfer by radiation and increase the furnace energy efficiency was analyzed. The objective is to find out effectiveness of the high emissivity coatings on the fuel consumption.
