Working Principle
Melting furnaces operate on the principle of generating and transferring sufficient heat to materials to reach and exceed their melting point, transforming them from solid to liquid states. The specific working principle varies depending on the type of furnace. For instance, induction melting furnaces utilize electromagnetic induction: a powerful alternating current flows through a coil, creating a rapidly reversing magnetic field that induces eddy currents within the metal charge. This resistance to the eddy currents generates intense heat directly within the metal, causing it to melt. Gas-fired and electric resistance furnaces, on the other hand, transfer heat primarily through convection and radiation from combustion or heating elements to the metal. Regardless of the heating method, the core objective is to achieve and maintain a homogeneous molten pool, often followed by pouring into molds for casting or further refining processes. Precise temperature control and efficient heat transfer are critical to ensure optimal melt quality and energy consumption.
