Conclusions

  1. 1.

    An oil-cooled electromagnetic plate is a simple and reliable mechanism for quenching flat parts.

  2. 2.

    Quenching on an electromagnetic plate, ensuring compression of the part at the beginning of the martensitic transformation, makes it possible to achieve relatively small distortions and satisfactory accuracy of the dimensions of disk-shaped parts.

  3. 3.

    It is fairly simple to change the quenching conditions (the attracting force, period of application, and other parameters) by changing the electrical parameters.

  4. 4.

    The cooling capacity of the apparatus connected to the electromagnetic plate is somewhat lower than that of an oil bath, but ensures through hardenability of parts 4–6 mm thick of steels 30KhGSA and 65G.

  5. 5.

    To reduce warping during quenching on an electromagnetic plate the distortion of the parts must be as small as possible (0.5 to 1.0 mm) and the surface must be free of scale.
