Induction Carbide Heating

How does carbide heating with induction work?

Improve your carbide heating process without a flame. Make the process of tipping and brazing carbide inserts efficient and safe with induction heating.

Induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpieces and filler to be brazed.

Benefits of Induction for Carbide Heating

Carbide tipping is a process for brazing a harder tip material to the body of a steel cutting blade, resulting in a tool that can last much longer and cut faster than steel alone.

Induction heating is ideal for this process since it focuses the energy on the carbide and the braze area in a flameless process without heating the entire tool.

Can Silicon Carbide be Heated by Induction?

Yes, silicon carbide can be heated by induction. Induction heating is a process that uses a rapidly changing magnetic field to induce an electric current in a conductive material. This current then generates heat, which can be used to heat the material. Silicon carbide is a semiconductor, which means that it has some conductivity. This makes it possible to heat silicon carbide by induction.

Induction Coil Silicon Carbide or Graphite?

The choice of material for an induction coil crucible depends on the type of metal being melted and the desired melting temperature. Silicon carbide (SiC) and graphite are the two most common materials used for induction coil crucibles.

SiC crucibles are more expensive than graphite crucibles, but they are also more durable and have a higher melting point. SiC crucibles are also less likely to contaminate the metal being melted. However, SiC crucibles can be brittle and can shatter if they are not handled carefully.

Can Carbide Heating be used for Boron?

Yes, carbide heating can be used for boron. Boron carbide is a very hard material that is used in a variety of applications, including cutting tools, armor, and abrasives. It is made by reacting boron oxide with carbon at high temperatures. Carbide heating can be used to heat boron carbide to the high temperatures required for these applications.
