چکیده انگلیسی
In order to improve heating performance of spot inductor and realize the hardening or cladding of complicated curve surface workpiece, two novel spot inductors were designed and their models coupled electromagnetic and temperature fields were built in ANSYS. Experimental validation was also carried out for these two inductors. The experimental temperature result was in good agreement with the simulation on workpiece surface. It indicated that the heating performance (including heating temperature and rate) of vertically aligned spot inductor was the highest among those spot inductors and its temperature value reached to 1660 °C in case of heating at 20s with the input power of 50 kW. With the same input power value, the heating performance of horizontally aligned spot inductor was better than that of the ordinary spot inductor. Moreover, the final temperature uniformity of horizontally aligned spot inductor was better than that of vertically aligned spot inductor, whose values are about 92.5% and 89.5% respectively. The local high temperature generated by vertically aligned spot inductor would melt many kinds of metal powder, and can be used for cladding and hardening of complicated curve surface workpiece.
