알루미늄 1톤을 녹이기 위한 유도 용해로의 소비 전력은 얼마입니까?

알루미늄의 비열용량은 0.88×103 J/(kg·℃), 융점: 660.37 알루미늄의 융해열은 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

총 열=558800+398000=956800KJ

킬로와트시당 열량은 3600KJ이며 난방효율은 보통 90% 정도이다.

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.
