What is an Induction Furnace?
AMELT Induction Technology
An induction furnace is an advanced electrical furnace that applies heat through induction heating of metal. The capacities of induction furnaces vary widely, ranging from less than one kilogram to over one hundred tons. These furnaces are versatile, used to melt various metals, including iron, steel, copper, aluminum, and precious metals.
Advantages of Induction Furnaces
The primary advantage of an induction furnace is its clean, energy-efficient, and well-controlled melting process, making it superior to most other metal melting methods. Modern foundries predominantly use induction furnaces, with many iron foundries transitioning from cupola furnaces to induction furnaces. This shift is due to the induction furnace’s ability to significantly reduce dust and pollutant emissions compared to cupola furnaces.
Induction furnaces do not require an electric arc, like an electric arc furnace, or combustion, as seen in blast furnaces. This feature ensures that the temperature of the charge (the material introduced into the furnace for heating) is maintained at the optimal level necessary for melting. Consequently, this precise temperature control helps prevent the loss of valuable alloying elements during the melting process.
