THE LAB determined 10 kW, 50-150 kHz induction heating system with a four turn, two-over-two helical coil would be optimal for this induction shrink fitting application. The frequency for this application was 132 kHz.
Initial testing was conducted to optimize the power delivered to the part. System power was applied for 14 seconds to reach the target temperature of 1000 ºF (538 ºC). The carbon graphite rings was then inserted and the assembly was allowed to cool which created a strong joint between the two pieces. This achieved the client's time and quality objectives.
For this shrink fitting application, induction heating offered several advantages. It delivered rapid heating which saved power and time. It's also a clean source of heat. Induction delivers less heat into the work environment than a torch and takes up less space than an... less

The method uses an open ended graphite die which is surrounded by a copper jacket.
Through which is poured molten metal. The graphite mold is typically water cooled.
This allows the molten metal to solidify within the die, the custom solid metal form is then extracted from the mold and pulled/passed through rollers and water sprays.
This process removes the heat from the metal, and gradually solidifies it.
Graphite Ring is a widely used in continuous casting.
The die molds are generally produced out of graphite.
In these types of applications, the types of graphite used are ISO-Molded types.
Small porosities and good machinability are required properties, and ISO-molded graphite has those.
In rare instances, where large ingots are produced, extruded graphite is used.
There are two types of continuous casting processes, a vertical casting and a horizontal... less
