for aluminum alloy melting, heat must be input to the aluminum alloy through one of three ways, namely conduction, convection and radiation. In comparison, radiative heat transfer has a relatively high efficiency, and different metals have different absorption effects for electromagnetic waves of different wavelengths. For aluminum alloys, the absorption wavelength is optimized due to the aluminum alloy (aluminum-copper, aluminum-silicon alloy, Al)2O3The absorption wavelength of the aluminum alloy is 0.95-2 microns, 4.2-12 microns and 1-15 microns) and is just in the infrared wavelength region (0.76-100 microns), so that the infrared radiation wave and the aluminum alloy just have a matching absorption effect, and the infrared radiation heating is an optimal mode. Meanwhile, by arranging the anti-radiation material in the smelting furnace, most of radiation energy can be concentrated in the aluminum alloy, so that the aims of high efficiency, low energy consumption, environmental protection and no pollution are fulfilled.
At present, a successful direct irradiation heating type aluminum alloy smelting furnace does not appear on the world, and in conclusion, the development of a set of economic, efficient and clean aluminum alloy smelting equipment based on an infrared radiation heating technology has important practical value and market prospect.
