What is the power consumption of an induction melting furnace to melt 1 ton of aluminum?

The specific heat capacity of aluminum is 0.88×103 J/(kg·℃), the melting point: 660.37 The heat of fusion of aluminum is 3.98×105J/kg,

1 ton of aluminum is heated from (25°C) to 660°C, and then melted. There are two parts of heat absorption, one part is heat absorption by heating, and the other part is heat of phase change.

Heating endothermic Q1=880×1000×(660-25)J=558800KJ

Phase change heat Q2=1000×3.98×105=398000KJ

Total heat=558800+398000=956800KJ

The heat per kilowatt-hour is 3600KJ, and the heating efficiency is usually around 90%.

956800÷3600÷90%=295.31

Therefore, it takes about 295 kWh to melt 1 ton of aluminum, which may not be particularly accurate. I hope I can give you a reference.
