Induction coil services — The Coil Works

Primary coil types — forging and mass heating

Built for the heat, not just for the fit

Open style ID cast solenoidal coil — finished coil — Finished coil

Solenoidal or RCS “Open Style ID Cast”

Best in class

OEM designs serviced: HIS, AIH, Interpower, Westinghouse

Only the ID is cast in refractory — the cast can be thicker or trowelled, giving the most robust refractory section available.
Hardwood board supports force the winding into alignment without the added cost of support studs.
Exposed insulated winding gives a visual means to inspect for shorting or overheating.
Reusable covers offered to reduce atmospheric contamination.
Alignment pins in the base and bottom board locate the coil to the heating line effortlessly.

Angle or molded frame “Fully Cast”

OEM designs serviced: Inductoheat, Beaver, IPE, Thermatool, CEFI

Older but more durable than a solid cast brick design.
Entire assembly cast in refractory — heavier and more expensive to repair long term.
End plates must be isolated from the aluminum frame; a failure point over time.
Coil is suspended while cast, so refractory thickness can fluctuate with vibration during the pour.
Reusable pouring forms help save repair cost over the fiber housing design.

Fiber housing “Fully Cast”

OEM designs serviced: ABP, Newelco, Pillar

European OEM-influenced design, very similar to the angle or molded frame coil.
Pressed laminate structural boards are typically rated slightly over 300 °F — forging heat burns out the binder.
Complete board frames are more expensive to repair when boards must be replaced.
We install corner-tapped brass blocks in place of heli-coil anchoring in the frame boards.
Structural boards act as the pouring forms for rebuilding.

Primary coil types — end heating and upsetting

High-volume indexing and tight floor space

Channel type coil — isometric drawing — Isometric drawing — select to view full screen

Channel type coil — finished coil — Finished coil

Channel type “Cast or Plate Lined”

OEM designs serviced: All manufacturers

Primarily for end heating and upsetting.
Used where high volume is required and a solenoidal pigeonhole coil cannot index cycle quickly enough.
Heating efficiency averages between the mid-40s and lower 60s.
Heated length is fixed with some versatility, typically at the expense of longitudinal uniformity.

Oval type coil — finished coil — Finished coil

Oval type “Fully Cast”

OEM designs serviced: All manufacturers

Used when planning around space constraints — bar end heating, plates and axle blanks for forming.
Limited adjustability of the heated length.
Upper ceiling refractory is the weakest point, due to the chimney effect of rising heat.
Replaceable high-temperature plates upgrade the roof life; rails and non-water-cooled wear strips can be embedded in the refractory floor for simple pusher indexing.
