Heating and quenching unit inductors

Heating and hardening inductors. The widespread use of induction heating for various types of heat treatment of products requires difficult methods of designing special high-frequency equipment.

Such equipment, first of all, includes inductors used to concentrate an alternating electromagnetic field in heated zones.

LLC “PP” Termolit Plus “makes calculations, manufactures inductors for heating and hardening installations, as well as induction hardening installations themselves. Induction heating of the metal occurs in an inductor, which is one of the main elements of a high-frequency installation, which largely determines the efficiency of the installation and the shape of the hardened layer.

The form of inductors in the field of induction heating and melting is very diverse. They can be cylindrical, flat, rectangular, slot-like, looped, shaped and other very complex configuration.

We create equipment for casting, heating, hardening, heat treatment of metal, equipment cooling systems. We design equipment, manufacture, carry out erection supervision, commissioning of equipment, train personnel.
We design and manufacture non-standard solutions for thermoelectric metal processing. In the production of components and assemblies for induction melting furnaces, we use high quality materials and the latest equipment and machines.

Types of heating inductors and their application

Types of heating inductors and their application

Cylindrical inductors are used in melting furnaces, all other types of inductors are used in heating and quenching installations. The main part of the inductor is the inductive conductor. The design of the inductor largely determines the heating and quenching result.

Inductors are divided into two groups: inductors for hardening at medium frequencies up to 10 kHz and inductors for hardening at high frequencies from 10 to 440 kHz. The inductor is a coil of round or rectangular copper tubes. It is necessary that the wall thickness of the tube is greater than the depth of current penetration into copper. For an inductor cooled with water during the entire period of operation, the wall thickness is 1.5 … 2 mm.

During spray hardening, when water enters the tubes only at the moment of cooling, the thickness of the walls of the active part of the inductor is taken equal to 4 … 6 mm; the inductor in this case is made cast or welded from separate sheets. To avoid short-circuiting the turns of the inductor, they are insulated with glass tape or mikanite tape impregnated with liquid glass. The inductor itself is lined with special high-temperature concrete. When installing the part in the inductor, it is necessary to maintain a uniform gap. It is not allowed to touch the part and the inductor during heating.
