- Abstract
Induction heating is a particular process which uses electromagnetic fields for heating conductive materials (steel, copper, brass, aluminium). The main difference from a traditional heating process is the location of heat sources which are distributed inside the work-piece. For this reason the induction heating process is very fast and controllable. Depending on the frequency used the heating can be superficial (induction surface hardening) or deep in the piece (forging, heat treatment etc.). The main advantages of this technology are: high production rate due to the high specific power delivered to the work-piece, high automation of the process, precise repeatability of treated pieces, in-line installation, low floor space needed, controllability of temperature with high precision, avoiding of deformation of pieces especially in surface hardening, primary energy saving, safe and clean work ambient for employees. There are a lot of applications where induction heating is used in different industries: melting of metals, heat treatments (hardening, tempering, annealing) , forging, hot rolling, surface hardening, cold crucible melting, welding, pre-heating, dry-coating, special applications. All these applications get benefits from the suitable characteristics of this technology. In this paper is presented the determination of the technological parameters for superficial hardening of axel pieces type made from 41Cr4 and 34CrMo4 steel. This technological parameters is optimum heating temperature, heating time and adequate cooling method for obtains a higher hardness.
