Using Induction Heating Systems To Harden Metals
Induction hardening is a kind of heat treatment which involves using induction heating to heat the metal that is then quenched. Throughout the quenching process, the metal undergoes change that hardens it, growing the brittleness too. The induction heating systems are utilized to harden selected regions of the part or set up, without having affected the whole part or even the qualities. Induction heating uses the key of electromagnetic induction that is a non contact heating process. It creates heat within the inside layer from the work piece. Earlier, traditional induction sealers were cooled by water, and also the turbine was once in the floor level. This was once attached to the sealing mind, mounted over the conveyor, by combined electrical and cooling cables. Modern sealing machines are air-cooled. This gives for any smaller sized machine. And also the entire unit could be mounted over the conveyor. ( induction heating machine ) Whenever a conductive materials are put into a powerful magnetic field, electrical current can flow within the steel creating heat. The present that's generated flows mainly within the surface layer. The depth from the layer is dependent upon surface power density, frequency of alternating field, the fabric thickness and permeability and also the heat time. By quenching the layer in oil, water or any other quenching agent, the top layer changes and becomes more difficult. The induction hardening process is generally employed for surface hardening of steel. An alternating magnetic field can be used to heat the constituents to temperatures which are above or
