Ajax TOCCO Induction Services...The Difference is Apparent

Heat Treating Coils

We have developed the special expertise to design, build and repair any size, shape or form of coils used for hardening, annealing, tempering and other heat treating and selective heating processes. necessary machine tools, materials and skilled craftsmen (yes, "craftsmen!") have been refined over the 21 years in the induction coil business. Coils and tooling for all types of induction heat treating applications are processed regularly. Quick disconnect coil adapters and water cooled bus can be supplied to suit your existing equipment. Coil laminations and other flux concentrator materials can be designed and fabricated for your specific application. Quench Chambers, rings and blocks are repaired and/or replaced if necessary.

Heating Coils

Put our experience to work for you. We can provide reduced overall costs compared to "in-house" coil repairs. Bar and billet heating coils that last longer save you money and reduce downtime. In-line heating coils for tube, wire, coating, annealing, etc., are rebuilt using a variety of construction methods. All types and manufacturer's coils can be repaired, rebuilt or modified including European coils. All styles of coils including cast refractory block type, 60 Hz tie-rod type, replaceable cast liners and open winding type with aluminum framework are regularly rebuilt. Our extensive experience and research in insulation coatings and refractories allow us to quickly rebuild and/or recommend improvements for increased efficiency or service life.

Melting Furnaces

A complete furnace rebuild or a coil repair, we are prepared to server you needs. Our facilities can handle a small lift/swing furnace or 35-ton furnaces and larger. We utilize our 80+ years of experience starting with the first induction melting furnaces.
We offer the latest advances in technology and materials. Our experienced craftsmen have access to extensive engineering and testing capability. We can provide the quality expected to ensure the repair or rebuild works properly when reinstalled and performs as anticipated.

Coreless Melting Coils

Coreless melting coils of all sizes and manufacturers, including European manufactured coils, and box furnaces up to 10,000 lbs. or more are rebuilt or repaired. High temperature graphite and other susceptor heating coils (4000° F and higher) and vacuum melting coils are within our capabilities. Cast refractory tops and bottoms are provided for box furnaces and complete furnace rebuilding is also available.
