The ratio of the emitted radiant flux per unit area of a sample to that of a black body radiator at the same temperature and under the same conditions. For application in low temperature steel, cast iron and aluminium alloys, it is made of aluminium. Real objects do not radiate as much heat as a perfect black body. Emissivity Table for Metals In the table below, please use the 8-14 micron column if you have an MT, ST, or MX. Emissivity Measurements of Molten Metals with an Electrostatic Levitator 340305-6 C p Atomic of liquid refractory metals has been measured mainly by two methods, levitation calorimetry and pulse heating. Thereafter, steel, which is refined from molten iron, is supplied to various types of product lines. For this problem, consider steady-state conditions and the surface numbering shown in the following schematic diagram (i.e. Continuous Temperature Measurement of Liquid Iron and Slag Tapped from ... . The laboratory emissivity of the material poured was 0.5; we measured the values shown on line. Compositional Dependence of Normal Spectral Emissivity of Molten Cu-Fe ...
