[Abstract]:Aiming at the problem of uneven temperature distribution in induction heating of single layer brazing superhard abrasive grinding wheel, the paper proposes to simplify the forming surface of grinding wheel to corresponding characteristic forming surface, and makes use of FLUX finite element simulation software. The influence of the structure size of coils and magnetic conductors on the temperature distribution during induction heating of concave and convex characteristic surfaces is emphatically analyzed, and the structure of the inductor for brazing is optimized by taking the single layer superhard abrasive grinding wheel with swallowtail groove as the object. The induction heating test was carried out on the swallowtail groove shaped grinding wheel with the optimized inductor structure, and the temperature distribution of the forming surface was measured by infrared thermal imager. The results show that the inductor structure obtained by this method can effectively improve the uniformity of the temperature distribution of ultra-high frequency induction heating on the forming surface, and the temperature difference between the different parts of the forming surface is less than 50 鈩，
