Thermal conductivity of sand casting axle housing ZG 40Mn

Generally, the thermal conductivity of metal is related to the temperature and chemical composition of molten steel, which is generally regarded as a constant or a linear function related to temperature. The thermal conductivity of low carbon steel at 0 ~ 1100 ℃.

In ProCAST simulation software, two calculation algorithms are provided for thermal conductivity calculation, one is lever algorithm (blue curve); the other is Scheil algorithm (green curve), and red curve is zg40mn thermal conductivity theoretical curve.

As shown in the figure, the calculation results by computer software show that the lever algorithm (blue curve) is close to the theoretical thermal conductivity curve by inputting the chemical composition of zg40mn, so the lever thermal conductivity curve calculated by software can be used.
