    The main function of an electric furnace for melting aluminum is to quickly melt aluminum raw materials, and its power depends on the specifications and design of the furnace.


    The following aspects can explore the efficacy and power of electric furnaces for melting aluminum (the power of electric melting aluminum furnaces of different specifications varies greatly, the following is for reference only):


    Efficiency Thermal efficiency: The thermal efficiency of an electric furnace refers to the ratio of the input electrical energy to the heat energy required to melt aluminum.


    Generally speaking, the thermal efficiency of an electric furnace can reach about 80% to 90%.


    Compared with traditional gas furnaces and oil furnaces, electric furnaces have higher thermal efficiency because electric heating elements can more accurately control and concentrate heat.


    Production efficiency: Production efficiency refers to the amount of aluminum that can be melted in a certain period of time.


    The production efficiency of an electric furnace is affected by many factors, including the design of the electric furnace, its capacity, the initial temperature of the aluminum, and the operating conditions. Generally speaking, the production efficiency of a small electric furnace may be from a few hundred kilograms to a few tons of aluminum per hour, while a large industrial electric furnace can reach tens of tons of aluminum per hour.

    Power is a key factor in the speed and production efficiency of melting aluminum in an electric furnace.


    It is usually expressed in kilowatts (kW) or megawatts (MW). Electric furnaces of different sizes have different power ranges: laboratory and small production electric furnaces are usually between 10 kW and 100 kW,


    medium-sized industrial electric furnaces are between 100 kW and 1 MW, and large industrial electric furnaces are usually more than 1 MW, and can even reach more than 10 MW.
