The use of induction furnaces for heating material that must undergo subsequent deformation by hot pressing, is now a consolidated practice that offers great advantages with respect to traditional heating systems such as gas furnaces, resistance or radiant panels furnaces, etc.
The great advantage in the pressing sector, where the heating process for work material is required continuously, is the total absence of pre and post operation downtimes. Other advantages include rapid reaction times to any temperature variation, rigorous reproducibility of operation parameters, easy automation of the entire line, easy adaptability to the different production needs of presses, hammers, forging machines, etc.
The electrical power required by the induction system depends on production needs, on the temperature, and on the cross-section and the type of material being heated. With regards to this last aspect, we would like to emphasize that furnaces can be built for any metallic material ( ferrous or non ferrous ) and of any cross-section ( circular, squared, tubular, flat, etc. ).

Heat Treatment
The use of induction heating for material treating is a consolidate procedure, both for the superficial hardening of metal parts or pipes, as well as for superficial treatments according to specific characteristics such as brassing, nitriding etc.
The possibility of obtaining high values of power density in the heating area makes induction heating fit even for continuous treating of wires or bars, as well as for pipes of large dimensions with great thicknesses.
Continuous induction hardening systems are often coupled with induction furnaces for material tempering on compact and extremely flexible lines.
Induction Hardening
Induction heating can also be applied for the thermal stabilization of the metallurgical structure of metals with different profiles, as well as for semi-finished products.
Continuous induction annealing is particularly appropriate for thermal condition stability of the material during the process, and for its repetitiveness over time using apposite thermo-regulation software.
Reduced dimensions of the plant layout with respect to conventional heating systems, high efficiency, accurate control of process parameters, and low system and operation costs, allow induction heating to be used even for the normalization of shaped mechanical parts when eliminating internal tensional states due to machining
Vacuum, Controlled Atmosphere
Heating systems with non-combustion heat sources are used when there is the necessity to remove any surface oxidation or whether heating cycle performances in controlled atmosphere are needed.

The introduction of induction heating systems in rolling processes is common among the most qualified producers of hot rolled steel sections. The main advantage linked to the use of an induction furnace, in the different parts of the roll train, is temperature control for different materials and different dimensions.
In fact, thanks to the absence of the thermal transistors of the application, and to the high value of specific power density per unit of volume, rapid responses in time of delivered power are possible, allowing to obtain the heating profile desired.
Generally, in the sector of hot rolling, bars are usually heated through intermittent passages. This increases the average temperature before intermediate forging or final machining, and allows to compensate the irregular head – tail temperature, making it possible to increase the system’s productivity by reducing gas consumption, as well as wear of the main furnace’s refractory material. Furthermore, it’s possible to carry out rapid changes in production while maintaining temperature control within common industrial standards, and reduce the number of defects due to temperature irregularity.
Induction is also present on the market with static heating operations for bars subject to subsequent hot rolling, allowing flexibility in production changes even with small lots of material, along with other advantages such as reduction of superficial decarburization even with atmospheric heating, elimination of ordinary maintenance costs of the gas furnace, and elimination of localized overheating in the combustion area.
