The interaction between aluminum liquid and the environment in the melting process, the transfer of heat during the melting process (thermodynamic process) The energy required for the solid metal to be heated and melted in the furnace is supplied by the heat source of the melting furnace.

Due to the different use of energy, its heating method is not the same, the basic furnace type is still the flame furnace.

Although the melting point of aluminum is low (660℃), due to the latent heat of melting (1.1 Interaction between aluminum liquid and the environment during melting process 1.1.1 Transfer of heat during melting process (thermodynamic process) The energy required for the solid metal to be heated and melted in the furnace is supplied by the heat source of the melting furnace.

Due to the different use of energy, its heating method is not the same, the basic furnace type is still the flame furnace. Although aluminum has a low melting point (660 ° C), due to the latent heat of melting (393.56KJ/kg) and the large specific heat (1.138kJ/(Kg·K) in solid state and 1.046kJ/(kg·K) in liquid state), the heat required to melt 1kg is much greater than that of copper.
