What is metal induction melting


Induction metal melting is a process that uses electromagnetic induction to melt metal.

What is metal induction melting

Types of induction cookers
There are two types of induction cooktops, each with specific requirements:

Core induction furnace
In a trough induction furnace, alternating current flows through a primary coil surrounding an iron core.Channel furnaces meet the needs of high-volume, high-volume operations requiring small alloy changes, as well as continuous casting projects.

Coreless induction cooker
The primary coil is a water-cooled copper coil surrounding a crucible or refractory lining containing the metal charge. The primary coil therefore induces current directly into the metal charge.

In addition, frequent alloy replacement and repeated cooling and heating operations will also shorten the life of the refractory lining. However, coreless refractory liners are also significantly cheaper and faster to replace.

Induction furnace refractory lining

Furnace lining refractory materials play a vital role in the smooth operation of induction furnaces. Stable refractory lining for optimal metallurgical performance. As a consumable pad

These eddy currents generate heat due to the material's electrical resistance, causing the material to heat up rapidly and eventually melt.

It has the advantages of high heating efficiency, precise temperature control, and the ability to melt metal quickly and evenly.

Additionally, it can be used in both small and large metal smelting operations. How does an induction cooker work?

An induction furnace is an energy-efficient, clean furnace used for melting all types of metals, including steel, iron, copper, zinc and aluminum.

Additionally, these types of ovens produce minimal waste and pollutants, helping to reduce your overall carbon footprint.

The principle of induction furnace:

Faraday's law describes how a magnetic field interacts with a circuit to produce an electromotive force, a phenomenon called electromagnetic induction.

Therefore, once a piece of conductive material (such as the charge in a furnace or a load) is placed in a changing magnetic field, an electric current is produced. When electricity flows, it encounters resistance and dissipates energy in the form of heat through the Joule effect.
