Abstract Electromagnetic induction heating technology has effectively saved steel manufacturing costs and actively promoted green manufacturing in the steel industry. Optimal design in the sprocket electromagnetic induction heating process is an important branch of producing high-quality sprocket. In the heat treatment of the sprocket,it is difficult to achieve uniform heating of the tooth profile of the ordinary circular coil at a single current frequency,which is easy to lead to uneven distribution of the hardness of the quenching layer,resulting in cracking of the sprocket. The profile coil has a better heating effect than the ordinary circular coil. Considering the actual processing cost and production demand,this paper proposes a kind of induction heating coil with a V-shaped angle at the top of the tooth,and the coil of the heater has a gap whose tooth tip is unequal to that of the tooth root. The electric-magnetic-thermal coupling temperature field model was established for the double sprocket,and experimental verification was conducted. It is found that this kind of coil with a V-shaped angle can improve the magnetic flux distribution in space compared with the circular coil,strengthen the proximity effect between the coil and the tooth root,weaken the proximity effect between the coil and the tooth tip,and improve the temperature uniformity of the sprocket along the tooth profile. A quantitative analysis was conducted to ascertain the effect of different electromagnetic parameters(current frequency and current density)and coil structural parameters(V-shaped angle and distance from the coil to the gear)on the heating rate and temperature uniformity. The V-shape angle structure of the coil is beneficial to improve the quality of electromagnetic heating of gear,which has important production value for promoting practical processing and application and improving the enterprise benefit,and it is conducive to promoting the production of the fine steel.
