An electric furnace refers to industrial and household electric furnaces that utilize the electrothermal effect for heating. Industrial electric furnaces are further divided into two types: resistance furnaces and induction furnaces. With the advancement of modern industrial technology, induction furnaces have become the most energy-efficient electric-to-heat conversion method among electric furnaces, widely used in fields such as households, medicine, chemicals, and metallurgy. Electric furnaces are characterized by rapid heating, easy temperature control, and high thermal efficiency.
