APPLICATIONS

Heat treatment systems for wires and braids.

PTo carry out inline (during production) actions of induction heating on wires and braids, ATE produces systems that heat the workpieces to be treated before hot galvanizing for example, or for drying after the bath, for polymerising paints or for brass coating wires.
These systems are designed for:

• Stabilization induction heat treatment of steel wires, braids and strands,
• Induction heating for drying, desiccation and surface plastic coating of wires, strands and profile strips,
• Induction heating for subsequent plastic coating of steel strands and cables,
• Annealing heat treatment to relieve stress in steel wires, strips and profiles,
• Induction heating for tempering surface martensite on steel wires,
• Hardening and tempering of steel wires, strips, profiles and steel wires for springs.

Multi-wire systems.

ATE has developed two induction heating systems for the treatment of parallel conductors: IMW is independent multi-wire heating, CMW is common-multi-wire heating.

These multi-wire induction heating systems do not pollute the environment, have compact dimensions compared to traditional resistance, gas, fluid bed furnaces or molten lead bath, guarantee high efficiency and upon request, can have closed-loop process control.

Bar and billet treatment systems.

Induction heating of bars and billets takes place in different industrial sectors, as in forging, in rolling mills for the hot production of steel and aluminium and in the subsequent hot rolling phase, as well as in the hardening and tempering of flat steel bars.

Induction heat systems for treating pipes.

ATE application for the continuous heating of pipes are intended for different treatment phases as drying, desiccation and painting, preheating, hot deformation machining, annealing, seam annealing of pipes, solubilisation of austenitic steels and hardening and tempering.

The induction heating procedure is chosen for its rapidity and precision in the various treatments.

Melting systems.

Using induction heating in melting systems is safer and more convenient compared to traditional methods. This is why ATE has chosen to develop this type of induction system for melting, which eliminates the flame and reduces accident risk, as well as ensuring high-quality processing.

Pan welding systems.

GDue to the induction heating technique, it is possible to weld small and large-sized mechanical parts of any shape and in different materials as steel, copper, brass, aluminium and more. The advantages of induction welding systems are the speed and the possibility to precisely localise the heat in the area to be welded, to minimise oxidation and deformation of the joints.

The company proposes braze-welding and press-welding systems.

Hot assembly systems.

The experience that ATE has acquired in the design and manufacturing of systems and equipment for the hot coupling of mechanical parts is the base of the continuous work of the company in always proposing customers new solutions with induction systems for heating:

• cage rotors for asynchronous motors,
• aluminium frames for asynchronous motors,
• rotors for synchronous alternators,
• motor bodies of special machines.

The hot assembly systems produced by ATE are also ideal for other applications as:

• hot insertion of the shaft of electric motor rotors,
• hot shrinking-on and shrinking-off of roll bearings,
• hot driving of shafts of gear pumps,
• assembly of planetary gear boxes.

Special heating systems.

For induction heating in non-standard contests, ATE proposes customized systems based on customers’ production requirements. Among these, the company proposes:

• Induction systems for the surface heating of cylinders on paper production lines,
• Induction heaters integrated in automated lines for the production of metal caps,
• Frequency converters for the heating of epitaxial reactors used in the semi-conductor production process,
• Induction heating system of “buffers” of a screen printing line for ceramic tiles,
• Two-stage modular station for the heating of aluminium alloy billets until the thixotropic status.

Induction generators.

ATE designs and manufactures standard induction generators and for customer applications. These solutions meet the technical characteristics and performance required by customers and are designed to adapt themselves to several production needs. ATE generators are designed to power the inductors that already exist on customers’ premises.
