induction heating service,induction heater,induction heating equipment and induction heating system are supplied by DaWei Induction Heating Machine Co.,Ltd
Induction heating is a form of non-contact heating for conductive materials, when alternating current flows in the induced coil, varying electromagnetic field is set up around the coil, circulating current(induced, current, eddy current) is generated in the workpiece(conductive material), heat is produced as the eddy current flows against the resitivity of the material.
Induction heating is a rapid ,clean, non-polluting heating form which can be used to heat metals or change the conductive material’s properties. The coil itself does not get hot and the heating effect is under controlled. The solid state transistor technology has made induction heating much easier,cost-effective heating for applications including soldering and induction brazing ,induction heat treating, induction melting,induction forging etc.<
DaWei induction annealing provides many advantages over other heating methods and is commonly used for annealing applications. Heating through induction provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time. Solid state systems are capable of heating very small areas within precise production tolerances, without disturbing individual metallurgical characteristics. Induction can be used for either surface or through heating; case annealing is possible depending on time, temperature and the material's characteristics.
Induction Annealing is a metal heat treatment in which a metal material is exposed to an elevated temperature for an extended time and then slowly cooled. Induction Annealing heat treatment is largely characterized by induced micro-structural changes which are ultimately responsible for altering the material's mechanical properties. The ultimate goal of this process is to reduce the hardness of the metal and improve its ductility.
