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. Induction heating makes use of the internal heat production on the heating material as for the Joule effect. This system is largely employed precisely when a heating in atmosphere is needed for steel white annealing, titanium pipe placement, cementification or nitriding of working tools, fusion in controlled atmosphere, etc. Furthermore the possibility to carry out a high power density allows to minimize possible bulks of the heating systems that need to be directly introduced in a production line. The long experience of Induction in the aforementioned fields permits to meet several production needs for high quality and reliability standards.
