Induction pre-heating

What is induction pre-heating?

Induction pre-heating is a process where materials or workpieces are heated by induction prior to further processing. The reasons for pre-heating vary. In the cable and wire industry, cable cores are pre-heated before insulation extrusion. Steels strips are pre-heated prior to pickling and zinc coating. Induction pre-heating also softens metals before bending, and prepares tubes and pipes for welding. Mobile pre-heating solutions facilitate onsite repairs of bearing assemblies.

What are the benefits?

SHAHAB Induction  systems are extremely efficient, resulting in major energy savings. When preheating steel strips and cable and wire, diode rectifiers ensure a constant power factor of 0.95, thus eliminating reactive power costs. Cycle times are short, too. And continuous automatic matching means a single coil can handle wide production ranges. Induction pre-heating systems are compact and easy to integrate into existing or planned production lines.

Where is it used?

Induction pre-heating is employed in the automotive, mechanical, aeronautical, electrotechnical, white goods and shipbuilding industries. A major area of use is preheating for welding. Our mobile  systems are used in the offshore sector for onsite weld pre-heating. Minac units are also frequently flown to oil platforms and airports to perform repairs and maintenance.

What equipment is available?

SHAHAB Induction designs and builds specialized systems for steel strip and wire and cable pre-heating. These systems typically feature our  equipment, and offer horizontal or vertical coil layout designs. Customized layouts are also available. Mobile and compact SHAHAB Induction units are used for onsite pre-heating.

No dust, no fumes, no noise. An SHAHAB Induction heater gets to grips with 170mm anode stubs.

Induction heating is used both domestic and commercial cooking, in several applications such as heat treating, soldering, preheating for welding, melting, shrink fitting in industry, sealing, brazing, curing, and in research and development.
