Arc Furnace vs. Induction Furnace: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on February 11, 2024
Arc furnaces use electric arcs to melt materials, while induction furnaces use electromagnetic induction for melting.

Key Differences

An arc furnace melts materials using an electric arc generated between electrodes, suitable for large-scale steel production. Induction furnaces, conversely, melt materials using electromagnetic induction, a process ideal for precise control over the melting process.
Arc furnaces are known for their capacity to handle large batches, making them common in heavy industry. Induction furnaces are smaller and more efficient, preferred in industries requiring meticulous alloy compositions.
In terms of energy consumption, arc furnaces require a high amount of electrical energy to generate the necessary heat. Induction furnaces are more energy-efficient, using electromagnetic fields to heat materials directly.
The operational speed of an arc furnace is relatively faster due to the intense heat from the electric arc. Induction furnaces, while slower, offer a higher degree of temperature control and uniformity.
Environmentally, arc furnaces produce more emissions and noise, posing greater environmental and occupational challenges. Induction furnaces are cleaner and quieter, aligning better with environmental regulations.
