For the most part, induction furnaces contain a coil that creates a rapidly reversing magnetic field. The magnetic field penetrates the material inside the furnace which induces circular electric currents which creates heat to complete the graphite purification process. Silicon carbide precast induction rings are used to protect these induction coils from the extreme heat.
The Importance of Design
Due to the thermal and mechanical stresses created when graphitizing carbon, induction rings must be precisely manufactured to ensure maximum operational performance. Our technology allows us to create a sealed shiplap to ensure no air leaks. Most importantly, at Onex, we engineer custom solutions to meet your production requirements.
Our experienced team of specialists will create custom molds to meet your specific diameter and height needs. In addition, we manufacture molds that allow for precise, repeatable shapes. On multiple ring silos, this is especially important as it allows us to replace any worn rings quickly and efficiently. Not to mention, our molding technology allows us to create a sealed shiplap to ensure airflow is not leaking in or out of the structure.
If you are experiencing a precast induction ring failure, a finite element analysis (FEA) can be performed. The analysis would identify operational issues leading to the failures. Once we know the problem, we will work with you to provide a solution. The goal is to get you back up and running as quickly as possible.
In addition to fabricating your custom induction rings, we also provide ancillary products such as nitride bonded silicon carbide (NiSiC) exhaust tubes and viewing ports. Maybe you need MICA slip plane products, ceramic fiber moldable joint compounds or refractory castable for stack bases. If your application requires, we are also able to manufacture custom precast bases and furnace lids.
